List of Custom Bearing Manufacturers: Our Top 10 Picks

Finding reliable custom bearing manufacturers has never been more critical — or more complex. As supply chains diversify and engineering tolerances tighten across aerospace, robotics, automotive, and industrial sectors, the gap between a manufacturer that truly understands your application and one that simply fills an order has never been wider.

This guide cuts through the noise. Whether you're dealing with a non-standard bore size, a harsh operating environment, or a regulated industry requirement that eliminates most suppliers outright, the manufacturers listed here represent a vetted cross-section of what the global custom bearing market actually offers in 2024 — from AS9100-certified US precision shops to engineering-driven Chinese manufacturers supplying OEMs worldwide. This guide is built for:

• Procurement managers sourcing non-standard or specialty bearings for the first time
• Design engineers evaluating suppliers for a specific application or material requirement
• OEM buyers comparing domestic and international manufacturing options
• Maintenance teams looking to replace obsolete or discontinued bearing designs

The ten manufacturers reviewed below span three countries, five bearing categories, and a wide range of customization approaches — read on to find the right fit for your application.

 

What Makes a Great Custom Bearing Manufacturer?

Not every supplier that offers "custom options" is a true custom manufacturer. Three things separate the real ones from the rest.

1. They start with engineering, not a catalog. A real custom bearing manufacturer asks about your load, speed, temperature, and environment before quoting. A distributor asks for a part number.

2. They control the full process in-house. Machining, grinding, heat treatment, assembly — manufacturers who own every stage hold tighter tolerances and catch problems before they reach you.

3. They can go from 5 prototypes to 50,000 production pieces. Custom capability means nothing if quality breaks down at scale. Ask for references from customers who've made that transition.

2. Waukesha Bearings

Overview:

Founded in 1946 and now part of Dover Precision Components, Waukesha Bearings operates in a category most bearing manufacturers don't touch: every product they make is custom-engineered. There are no catalog items, no standard sizes pulled off a shelf. Each bearing is designed around a specific rotating equipment application — compressors, turbines, pumps, generators, or gearboxes — drawing on 80 years of rotordynamic expertise to solve problems that conventional rolling element bearings simply cannot.

Establishment: 1946

Headquarters: Pewaukee, Wisconsin, USA

Core Products:

• Hydrodynamic fluid film journal bearings & thrust bearings
• Active magnetic bearing (AMB) systems with integrated controllers
• Tilt pad bearings for high-speed rotating equipment
• Integral squeeze film dampers for vibration control
• Brush seals for gas turbines & compressors
• Rotordynamic analysis & bearing diagnostic services

Why Engineers Specify Waukesha for Critical Rotating Equipment:

Waukesha's strength isn't product breadth — it's depth of engineering on individual applications. Their team conducts full rotordynamic modeling before a bearing is ever manufactured, analyzing shaft dynamics, load conditions, and operating speeds to arrive at a geometry that performs reliably over the equipment's service life. This is particularly relevant in oil & gas, power generation, and marine industries, where bearing failure means unplanned downtime measured in days, not hours. If your application involves high shaft speeds, variable loads, or environments where contact bearings would fail, Waukesha is one of the few manufacturers structured to take it on from analysis through to production.

4. Franke GmbH

Overview:

Franke didn't just manufacture bearings — they invented an entirely different category of bearing. In 1934, founder Erich Franke developed the wire race bearing while searching for a more compact solution for optical instruments at Carl Zeiss. Nearly 90 years later, Franke GmbH remains headquartered in Aalen, Germany, with 340 employees and a product line where 95% of all bearings shipped are custom solutions. The wire race principle — where rolling elements run on precision wire races rather than solid ring raceways — allows the surrounding structure itself to become part of the bearing, enabling designs that are dramatically lighter and more compact than conventional alternatives.

Establishment: 1936

Headquarters: Aalen, Germany

Core Products:

• Wire race bearings, 40mm to 2,000mm diameter, infinitely variable sizing
• Slewing rings and rotary joints in steel, aluminium, plastic, and non-ferrous metals
• Lightweight bearing solutions for robotics, CT scanners & surgical equipment
• Bearings with integrated gear, direct drive, or torque motor
• Aluminium linear guidance systems and positioning tables
• Clean room specified and grease-free bearing variants

The Case for Franke When Standard Bearings Won't Fit:

Franke's 4-point contact principle gives designers a level of geometric and material freedom that solid-ring bearings cannot match. The housing material — steel, aluminium, plastic, carbon fibre — becomes a design variable rather than a constraint, and drive systems can often be made smaller as a result, with documented energy savings of up to 30%. This makes Franke a particularly strong fit for robotics joints, medical imaging equipment, and aerospace applications where envelope size, weight, and cleanliness requirements all pull in the same direction. With representatives in 28 countries and a direct engineering collaboration model, Franke works at the concept stage rather than being handed a finished drawing to quote.

7. THB Bearings

Overview:

THB Bearings is a China-based manufacturer that operates under its proprietary RORKS brand, positioning itself as an application engineering partner rather than a volume supplier. Their approach centers on analyzing the customer's specific operating conditions — load direction, speed, environment, service life requirements — before proposing a bearing solution, which may be a modified standard design, a fully bespoke bearing, or a complete bearing system including adjacent components.

Headquarters: China

Core Products:

• Track rollers and cam followers for industrial automation
• Crossed roller bearings for precision positioning applications
• Slewing rings for cranes, wind turbines & rotating platforms
• Tapered, cylindrical, spherical & needle roller bearings
• Deep groove ball bearings in standard and engineered configurations
• Bearing solutions developed against customer application data

Application Engineering as the Starting Point:

What distinguishes THB from many Chinese bearing manufacturers is the emphasis on failure analysis and application review before a bearing is specified. Their team works to understand why an existing bearing is failing — or why a standard bearing won't work — and builds the solution around that root cause. This makes THB a more practical choice for buyers who have a problem to solve rather than a part number to replace, and their RORKS brand reflects a deliberate effort to build a consistent quality identity separate from OEM supply.

10. BOM Bearing

Overview:

Founded in 2005 and headquartered in Shaoxing, Zhejiang, BOM Bearing is an engineering-driven manufacturer specializing in non-standard and integrated bearing solutions for automation, robotics, and industrial machinery. Where most bearing manufacturers modify existing designs, BOM develops patented integrated bearing products that combine multiple components — bearing rings, gears, cams, flanges — into a single precision-machined unit, eliminating the assembly tolerances and concentricity errors that arise when separate components are press-fitted together.

Establishment: 2005

Headquarters: Shaoxing, Zhejiang, China

Core Products:

• Flange integrated bearings combining outer ring and flange in a single component
• Cam-slider combination bearings (patented) for embroidery and packaging machinery
• Gear integrated bearings with internal or external teeth machined from the same ring blank
• Slim and super-slim crossed roller bearings for collaborative robots and medical robotics
• Telescopic forks for AS/RS automated storage systems
• Bearing solutions for robotics, automated warehousing, agriculture & e-bikes

Why BOM's Integrated Bearing Approach Matters for Automation Applications:

BOM's core argument is straightforward: integrating the bearing and its adjacent components into one machined part removes the tolerance stack-up that separate assemblies introduce, delivers better concentricity, and simplifies installation. Their gear integrated bearing, for example, machines the gear teeth and bearing raceway from the same ring blank in a single clamping setup — achieving transmission accuracy that a press-fitted gear ring cannot match, while also providing 30% higher load capacity within the same envelope. With 550+ employees, a 150,000m² facility, and over 20 years of production experience, BOM has the manufacturing scale to support both prototype development and series production for OEM customers worldwide.

Frequently Asked Questions About Custom Bearings

A few questions that come up consistently when buyers are sourcing custom bearings for the first time.

What information do I need to provide to get a custom bearing quote?

At minimum: bore diameter, outer diameter, width, load type and magnitude, operating speed, and the environment the bearing will run in. Material preferences and required tolerances help too. If you don't have all of this, a manufacturer with application engineers can help you work through it.

What's the typical lead time for custom bearings?

For prototypes, expect 4–8 weeks depending on complexity and material availability. Production runs vary widely — simple non-standard sizes may be ready in 3–4 weeks; complex aerospace-certified designs can take 3–6 months. Always confirm lead time before placing an order.

Is there a minimum order quantity for custom bearings?

It depends on the manufacturer. Shops like ZMS Bearing and BOM Bearing are set up for small-batch and prototype work with low or no minimum. Large manufacturers like Schaeffler typically require higher volumes to justify custom tooling costs.

Can I get custom bearings made to replace an obsolete part?

Yes. Reverse engineering from a physical sample or old drawing is a standard service at manufacturers like BDS Bearing and BMC Bearing. Provide the original bearing or key dimensions, and they can produce a functional equivalent — often with material or tolerance improvements.

What's the difference between a custom bearing and a modified standard bearing?

A modified standard bearing starts from an existing design — changing a seal, adding a groove, or adjusting the clearance. A true custom bearing is engineered from scratch to fit a specific application. Modified bearings are faster and cheaper; custom designs offer better optimization when no standard bearing comes close to the requirement.

Do Chinese custom bearing manufacturers meet international quality standards?

Many do. ISO 9001 certification is common across the Chinese manufacturers in this guide. For high-precision applications, manufacturers like E-FIND Bearing and BOM Bearing produce to P2/P4 accuracy grades that match European standards. That said, certification level and actual quality control vary by factory — requesting inspection reports and sample testing before committing to a production order is always worth the time.

Can custom bearings be made in plastic or ceramic?

Yes. Plastic bearings (PEEK, PTFE, nylon) are used in food processing, medical equipment, and corrosive environments where metal would fail or contaminate. Ceramic bearings handle extreme temperatures, electrical insulation requirements, and very high speeds. ZMS Bearing and Lily Bearing both offer these material options with custom sizing.

 

Ready to Source Custom Bearings?

The ten manufacturers in this guide cover the full spectrum — from NADCAP-certified US aerospace shops to flexible Chinese non-standard bearing producers. No single supplier is right for every application.

If you already have a drawing and defined specifications, you're ready to reach out. If you're still working through the application, start with a manufacturer that offers application engineering — they'll help you define the spec before they price it.

If your application involves non-standard sizes, integrated bearing designs, or automation-focused solutions, BOM Bearing is worth a close look — their engineering team works directly with OEMs from concept through to series production.
