ball bearings

It’s been half a century since we developed the first plastic bearing in the industry. We are pleased to say that our bearings have been used by customers from a wide range of industries. To meet various demands, we provide various bearing materials, including POM (Polyacetal), PE(Polyethylene), PEEK (PolyEtherEther-Ketone), PVDF(Polyvinylidene fluoride), SUS(Stainless), and Ceramic for the following applications: Refrigerators, cabinets, copying machines, cash machines, registers, arcade machines, machine tools, etc.

With TOK’s over 75 years of expertise and proprietary experience in radial ball bearings, we can guarantee that your specific application will be fully met with our products. TOK can provide the outer races of the bearings in numerous configurations, and use both standard and custom-designed bearings to meet your requirements. We would be happy to take your concept and specifications to design and manufacture a customized bearing for your needs.

Featuring steel inserted inner races, this family of ball bearings was designed to carry medium loads. Typical applications include heavy-duty filing cabinets, professional office equipment, tool cabinets, and any storage equipment where heavy drawers are subject to intense usage.


This TOK Steel bearing has a screw function, featuring SUJ2, STKM, and/or SWCH materials.


Our smoothest bearings are made with a steel inner race, and POM outer race. These are used for any cabinet type drawers, and support office equipment machines up to 80kg (176lbs)

Special Needs Bearing

We are completely equipped with bearing that can be used in special enviromments
・Chemical resistant: C series, PE series, & PK series
・Heat resistant: C series & PK series
・Corrosion resistant: S series
・Anti-Static: E series


Using the D-series as a foundation, the K-series was developed as a more precision focused version of the D-series. The K-series offers closer tolerances and better accuracy. The outer races can be custom designed for your application. The assembly can include timing pulleys, sprockets, and gears that may be required in sophisticated appliances such as copy machines, printers, and vending machines.
