SRG manufactures plastic race ball bearing types in single and double row radial, 3- piece thrust, four point contact, thin section, skatewheel ball bearing, insert ball bearing with plastic mounted blocks in either flange or pillow type. 

SRG plastic ball bearings made from the A500 material are temperature resistant up to 302° F, while those made from the B180 material are designed for temperatures up to 176° F.

We use top grade materials such as: Acetal, Nylon, Polypropylene, Polyethylene, KYNAR, PETP, PBT, PEEK, Ceramic and Stainless Steel in different combinations to meet specific needs. Jilson’s housings for plastic bearings are made of high-grade, solid PBT thermoplastic polyester. plastic nsk bearings are ideal for: food and beverage industries, photo processing facilities, major appliance or furniture industries, many marine applications, chemical and electroplating industries, paint and dye manufacturers, textile industries, automotive manufacturing or service, water treatment plants, pharmaceutical industries, outdoor applications and more. 

Plastics absorb shock loads better than metal due to their elastic nature. Many conventional radial ball bearings fail due to brinelling of the raceway, ie: balls denting the raceway. There are three reasons steel bearings require lubrication; to reduce friction, dissipate heat and resist corrosion. Plastic, by nature, does not corrode. Due to the design of plastic nachi bearings, there is no metal to metal contact, resulting in less friction; therefore dissipating heat becomes less critical.

plastic ball bearings run freer and naturally have low inertia due to the low coefficient of friction between plastic and stainless. Two other factors contributing to low inertia are the ability to run without grease and being lighter in weight.
