The SEALMASTER ER series insert bearing is a ball bearing with an extended inner ring, designed to be mounted in split or one-piece housings. It is used in equipment where the shaft rotates and needs a compact, easy-to-mount support, such as conveyors, fans or mixers. MR Accesorios Industriales supplies this line for industrial plants in Buenos Aires and throughout the country.

The ER series designation is read as ER followed by a number and the letter R. The number indicates the bore diameter in inches or its metric equivalent, and the final R identifies the extended inner ring with a groove for the locking system. For example, ER-20R and ER-32R correspond to different shaft sizes. If you need another size, write to us with the full part number.

These inserts are used in belt conveyors, bucket elevators, centrifugal fans, mixers and process equipment. In Argentina they are common in food, cement, paper and aggregate processing plants, where a sealed bearing that withstands dusty or humid environments is required. They are also used in agricultural machinery and packaging lines.

To select the insert, take into account the shaft diameter, the type of load and the environmental conditions. Labyrinth or contact sealing protects against contaminants; it is advisable to verify that the housing is compatible with the ER series. During mounting, ensure the alignment of the housing and the shaft, and lubricate according to the operating conditions. The shaft is secured with the set screws of the inner ring.

Insert bearings from different brands are often interchangeable if the main dimensions and the locking system match. However, always verify the tolerances and the type of sealing before replacing. At MR Accesorios Industriales we tell you the alternative compatible with your equipment and quote the ER series you need.
