A LINK-BELT ER series insert bearing is a ball bearing built with an extended inner ring. It seats inside a split plummer block or pillow block housing to create a complete bearing unit that carries a rotating shaft. Typical duty covers power transmission, conveying and process equipment where space is tight and mounting needs to stay simple.

Reading the code helps you order the right piece. The letters ER mark the extended-inner-ring insert family, and the digits after them give the shaft diameter in inches or the matching metric size. A trailing S points to a particular sealing or locking arrangement inside the series. So a reference such as ER20S means an insert for a 20 mm shaft, or its equivalent, in the S version. The safest way to order is to copy the full number printed on the equipment or the housing.

You will find these inserts on belt conveyors, bucket elevators, mixers, mills, packaging lines and other process equipment in food, chemical, cement and material handling operations. Because they sit in split plummer block housings, service work and replacement go faster, since the whole assembly does not have to come apart.

Selection comes down to three things: shaft diameter, housing type and the sealing the environment demands, whether that means dust, moisture or regular washdowns. During installation, align the housing, tighten the locking screws on the inner ring and lubricate to suit the operating conditions. On equipment with vibration or axial loads, it pays to verify clearance and how the insert fits in the housing.

These inserts interchange with other brands that follow the same standardized nomenclature and dimensions. Before swapping one out, check the shaft diameter, the inner ring width and where the locking holes sit. If anything is unclear, send a photo of the number engraved on the bearing or housing and we will point you to a compatible alternative.
