Basic information Plastic bearings are corrosion resistant bearings made of variuos materials. Our standard plastic corrosion resistant bearings have acetal resin (POM) rings, nylon (PA66) cages and balls made from 316 stainless steel or glass (GL).
We also offer corrosion resistant bearings made of other materials, like PTFE or PEEK. They are used for highly corrosive environments and high temperatures. We normally offer standard plastic bearings 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.
Standard plastic bearings are only suitable for low loads and low speeds and should not be used in temperatures greater than 90C. PEEK and PTFE can be used up to 260C.
Plastic bearings are dedicated for shafts of diameter from 3 to 30 mm (in metric sizes) or from 0.125" to 1.0" (inch sizes).
Special orders: Other sizes of plastic bearings are available but may be subject to minimum order quantities.
