A SEALMASTER ER series insert bearing is a ball bearing built with an extended inner ring, made to sit inside split plummer block housings and bearing units. Conveyors, fans and agricultural equipment rely on this style of insert where smooth rotation and radial support are needed. MR Industrial Accessories LLC supplies this line and can help you match the right reference to your equipment.

Reading the code helps you order with confidence. Take ER-20RT: the ER prefix identifies the series, the 20 points to the shaft size under that series convention, and the RT suffix covers construction details such as sealing style or outer ring shape. Before selecting a part number, confirm the shaft dimensions and the housing type it will sit in.

These inserts fit split plummer block housings, which is convenient for maintenance: you can replace the bearing without pulling the whole shaft. Typical service includes food processing plants, material handling, bottling lines, ventilation systems and farm machinery, running at moderate radial loads and medium speeds.

Selection comes down to three checks: shaft diameter, locking method (set screw, eccentric or adapter) and the sealing needed for the environment. Alignment at mounting matters, since poor alignment adds stress. Factory grease usually covers normal service; harsher conditions may call for periodic relubrication. Follow the manufacturer's guidance on tightening and on cleaning the seat.

When comparing with another brand, line up the critical dimensions: bore, outer diameter, width and locking type. Interchangeability is not automatic, so verify tolerances and housing design. We can point you to an alternative that matches your current part number.
