High Performance Custom Bearings

Schatz design and manufactures custom versions of any of our standard products. We can also supply you with custom bearings if you’re starting from scratch and have a brand-new concept. 

Find out how we can design and manufacture custom ball bearings for your specific application, or keep reading to learn more about Schatz’s design and manufacturing capabilities. 

You’ll also find information about applications, and products by industry and type.

Custom Bearing Design

Schatz designs custom bearings and can prototype, analyze for performance, and provide full production allotment – even for small lots. We’ll test your custom products extensively using industry-leading analytical tools. Our world class-design team analyzes bearing performance using key metrics, including load and speed requirements, along with environmental factors that affect performance.

Plus, our Application Engineers can work with you to modify standard bearing characteristics based on your specific requirements. This includes considerations such as materials of construction, surface treatments, size and number of rolling elements, ring sections, clearance/preload, cage and seal design, anti-rotation devices, and lubrication holes.

Custom Bearing Applications

Schatz can design and manufacturer custom products for any application, including challenging operating environments with heavy loads or shock loads, torque sensitive mechanisms, requirements for high precision and accuracy, and contaminated or corrosive environments. Our custom bearings can also incorporate features such as special internal components.

Custom Bearings by Industry

Aerospace Bearings

Schatz designs and manufacturers the following types of custom aerospace bearings.

    • Airframe control bearings are used in flight control systems and drive system for aircraft.
    • Aircraft bearings are used in airframe applications, flight control systems for fly-by-wire, and in conventional flight controls
    • Space bearings are designed for mission-critical applications and, with satellites and spacecraft, vacuum conditions.
    • eVTOL bearings are used in electrical vertical take-off and landing (eVTOL) aircraft, typically in electric motors, generators, and gear boxes.

Bearings for Military and Defense

Schatz also designs and manufacturers custom bearings for military and defense-related applications. The advantages of working with us include:

    • DFARS compliant options for most custom bearing designs
    • ITAR registered and NIST 800-171 cybersecurity compliant manufacturer 

Medical Bearings

Custom medical bearings can be used in pumps, centrifuges, respirators, ventilators, X-ray, scanning, robotic surgical equipment and other applications.

Semiconductor Bearings

The custom semiconductor bearings that Schatz designs and manufactures are used in wafer processing, photolithography, robotics, polishers, dryers and other chip manufacturing applications. They include custom thin section bearings with a high degree of precision.  

Custom Bearings by Type

Precision Bearings

Custom versions of standard precision bearings can have ABEC 1, 3, 5, or 7 tolerances. They are available for light, extra light, and extremely light duty with medium, metric, or inch-based precision.

Thin Section Bearings

Custom thin section bearings are designed for use in tight spaces and hard-to-reach places. They appear thinner than standard ball bearings because their cross-section doesn’t become larger as bore diameter increases. 

Angular Contact Bearings

Custom versions of Schatz’s angular contact bearings are designed to support both radial and axial loads. They work by axially displacing the inner and outer ring raceways relative to each other, which causes the balls to contact the raceways at an angle. 

Unground and Semi-Ground Bearings

These custom products are single row radial bearings with precision levels less than ABEC 1. Typically, unground bearings have tolerances 10 times greater than those of precision-ground bearings.

Additive Manufacturing Bearings

Custom products can be produced with 3D printing (additive manufacturing) instead of traditional bearing manufacturing processes. Additive manufactured bearings are available in a choice of materials and are often used in difficult applications. Single-piece assemblies with mating components help to reduce complexity.
