Plastic Metric Bearings

Plastic ball bearings are most commonly stocked with acetal resin (POM) rings and nylon (PA66) cages. The balls are normally 316 grade stainless. These plastic bearings are generally used as corrosion resistant bearings, non magnetic bearings or non-conductive bearings. We can also supply corrosion resistant and chemical resistant plastic bearings made from materials such as polypropylene or PEEK.Plastic bearings can only support low loads and low speeds and should not be used in temperatures greater than 90°C. PEEK can be used up to 260°C. Our plastic bearings are normally open but they may also be supplied with shields or seals on request. Plastic bearings are not precision grade. Normal inner and outer ring tolerances on these bearings are +/- 0.1mm. Larger sizes can be supplied to order.
