The SEALMASTER ER series insert bearing is a ball bearing with extended inner ring, designed to be mounted in split plummer block housings and bearing units. It is used in equipment requiring smooth rotation and radial support, such as conveyors, fans and agricultural machinery. MR Accesorios Industriales supplies this brand and advises you on choosing the correct reference for your application.

The ER series designation combines letters and numbers that identify the insert. For example, ER-20RT: the letters ER indicate the series, the number 20 refers to the shaft diameter in inches or millimeters according to the series convention, and the RT suffix indicates construction features such as the sealing type or the outer ring shape. To select the exact part number, take into account the shaft dimensions and the type of housing where it is mounted.

These insert bearings are used in a wide variety of industries in Argentina: food plants, material handling, bottling equipment, ventilation systems and agricultural machinery. Their design allows mounting in split plummer block housings, which facilitates maintenance and replacement without disassembling complete shafts. They are common in applications with moderate radial loads and medium speeds.

To choose correctly, check the shaft diameter, the locking type (set screw, eccentric or adapter) and the required sealing according to the environment. Mounting must ensure adequate alignment to avoid additional stresses. Factory lubrication is usually sufficient, but under severe conditions it may require periodic relubrication. Follow the manufacturer's recommendations for tightening and seat cleaning.

When looking for equivalents with other brands, compare the critical dimensions: bore diameter, outer diameter, width and locking type. Interchangeability is not automatic; always verify tolerances and housing design. MR Accesorios Industriales can indicate the alternative compatible with your current part number, maintaining the original performance.
