CW Bearing is a global manufacturer of precision bearings and motion components supporting a wide range of high-performance, mission-critical applications across automation, robotics, medical, aerospace, automotive, and precision equipment markets. With an annual production capacity exceeding 300 million bearings, CW Bearing delivers both standard and custom-engineered solutions where accuracy, reliability, efficiency, and long service life are essential.

CW Bearing’s product portfolio includes deep groove and angular contact ball bearings, roller bearings, ball screws, and worm shafts, engineered for rotating and linear motion in compact, high-load, and high-speed environments. Bearing sizes range from 7 mm to 90 mm OD (0.276? to 3.543?), supporting everything from miniature precision instruments to larger motion assemblies.

Our components are used in applications such as:

Robotics & Automation: robot joints, actuators, encoders, gearboxes, brushless motors, conveyors, and automated production equipment

Medical, Surgical & Dental: surgical robotics, imaging systems, dental handpieces, diagnostic equipment, and precision motion devices requiring low noise and high cleanliness

Aerospace & Space Systems: flight-control mechanisms, electromechanical actuators, and LEO/NEO satellite subsystems where reliability, material control, and consistency are critical

Automotive & Off-Road: electric and hybrid drivetrains, steering systems, braking systems, transmissions, and auxiliary motors for on- and off-highway vehicles

Precision Tools & Equipment: power tools, machine tools, instrumentation, and high-accuracy motion assemblies

CW Bearing offers multiple material and design options, including chrome steel, stainless steel, and hybrid ceramic configurations, along with optimized retainers, seals, and lubrication systems. Oil and grease lubrication options are selected based on speed, temperature, torque, noise, and service-life requirements. Worm shafts and motion components are produced to application-specific tolerances, with surface finish, pitch accuracy, and performance characteristics tailored to customer requirements.

Manufacturing is supported by ISO/TS 16949 and ISO 14001–certified facilities, ensuring rigorous quality control from incoming material inspection through final assembly. CW Bearing operates globally with manufacturing capabilities in China and Mexico, supported by U.S.-based engineering and technical sales teams to enable close collaboration during design, validation, and production ramp-up.

CW Bearing partners with OEMs, Tier suppliers, system integrators, and design engineers to deliver cost-effective, scalable motion solutions—from early concept and prototyping through high-volume production. Our combination of engineering depth, global capacity, and flexibility allows us to support evolving technologies across multiple industries.
