The SEALMASTER ER series insert bearing is a ball bearing with an extended inner ring that mounts into split or solid housings. It suits equipment with a rotating shaft that needs compact, straightforward support, such as conveyors, fans or mixers. MR Industrial Accessories LLC supplies this line to industrial plants across the United States and in several Latin American countries.

The part number follows a simple pattern: the letters ER, then a number, then the letter R. That number gives the bore diameter in inches or its metric equivalent, and the trailing R indicates the extended inner ring with a groove for the locking system. So ER-20R and ER-32R are two different shaft sizes. If you need a size you do not see listed, send the complete part number and we will take it from there.

Typical applications include belt conveyors, bucket elevators, centrifugal fans, mixers and process equipment. In food, cement, paper and aggregate processing plants, a sealed bearing that handles dusty or humid conditions is often required. You will also find these inserts in agricultural machinery and packaging lines.

When selecting an insert, consider shaft diameter, load type and the environment. Labyrinth or contact sealing keeps contaminants out, and it is worth confirming that the housing is compatible with the ER series. During mounting, check alignment between housing and shaft, then lubricate according to the operating conditions. The shaft is secured with the set screws on the inner ring.

Insert bearings from different brands are frequently interchangeable when the main dimensions and the locking system match. Even so, verify tolerances and sealing type before replacing. Our team can point you to the compatible alternative for your equipment and quote the ER series you need.

If you are sourcing an insert bearing for your application, send the part number or shaft dimensions by WhatsApp or email. We reply promptly and help you choose the right option, including checking interchangeability with other brands and series.
