Plastic Bearings
Metric and inch series to fit shaft sizes from 6mm up to 25mm
Acetal resin with stainless steel or glass balls

Plastic bearings are manufactured with plastic (acetal resin) rings & balls and 316 grade stainless (316 suffix) or glass balls (GL suffix) for use as corrosion resistant bearings or non magnetic bearings. We can supply to order plastic bearings with polyethylene rings and glass balls for more corrosive environments. All plastic bearings are only suitable for low loads and low speeds and should not be used in temperatures greater than 90C. We normally stock these open but they may also be supplied as ZRS with one acetal shield and one rubber seal. Plastic bearings are not made to the same tolerances as steel bearings. Normal inner and outer ring tolerances on these bearings are +/- 0.05mm. Other sizes of plastic bearings are available but may be subject to minimum order quantities.
