Plastic Pillow Block Bearings

Plastic pillow block bearings are designed to replace cast and stainless steel pillow block bearings in applications that are extremely abrasive or are required to conform to USDA and FDA requirements. Our high-quality plastic pillow block bearings are manufactured from premium virgin UHMW and have a molecular weight of at least 4.2 million for extended wear life and performance. Standard bore sizes range from 1/2" up to 3" inside diameter; these bearings are manufactured to standard bearing dimensions (bolt holes, hole spacing, base height, etc.) so they can directly interchange with common brands, eliminating equipment adjustments and modifications. The standard operating temperature for these bearings is 200°F; however, for high-temp applications, we also produce these bearings in an acetal material capable of operating up to 600°F. Additionally, UHMW plastic pillow block bearings are self-lubricating due to the properties of the plastic material. For information on new applications, refer to our plastic bearing insert page and scroll down to the required data. For pricing and availability or additional information, contact our customer support team, and we will be happy to assist you!
