Plastic bearings with stainless steel or glass balls to fit shaft sizes from 0.125” up to 0.75” diameter.
SMB plastic ball bearings are available from stock in the UK with acetal resin (POM-
As the material is softer, plastic bearings are intended for light loads and low speeds. The maximum temperature for acetal bearings with a nylon cage is 100°C. PEEK can be used up to 250°C. These bearings can often be supplied with plastic shields on request. Plastic bearings are not precision grade. Inner and outer ring tolerances on these bearings are much wider than tolerances for precision steel bearings.
