The SEALMASTER ERPBA pillow block housing is a pillow block mounted bearing: a compact unit that combines an insert bearing with a cast housing, ready to bolt to a flat base. It is used to support rotating shafts in equipment where rigid support and simple mounting are required, with the advantage that the unit comes pre-assembled and aligned from the factory. It is a common solution in conveyors, fans, mixers and process machinery, and is available in metric sizes within the ERPBA series.

The ERPBA series designation reads as a sequence of letters and numbers that identifies the housing type and its size. In the examples ERPBA-45MM-2, ERPBA-50MM-2 and ERPBA-55MM-2, the letters ERPBA correspond to the pillow block housing family; the number that follows —45, 50, 55— indicates the shaft diameter in millimeters, and the final -2 suffix distinguishes a construction variant within the same series. You will find sizes from 45 mm to 80 mm, such as ERPBA-60MM-2, ERPBA-70MM-2 and ERPBA-80MM-2, to cover different shaft sizes.

These housings are chosen in food, beverage, cement, mining and aggregate processing plants, where equipment works with dust, humidity or frequent washdowns. They also appear in belt conveyors, bucket elevators, mixers, centrifugal fans and pumps. In Argentina, MR Accesorios Industriales supplies them for replacement and for new projects, and combines them with other power transmission components the company distributes, such as pulleys, chains and bearings.

To select the right housing, take into account the shaft diameter, the radial and axial load it will support, and the environmental conditions. The ERPBA series allows mounting on a flat base with two holes; it is advisable to check alignment between housings and to control the tightening of the fastening bolts. If the equipment works with a lot of dirt or water, it is important to check the sealing of the insert bearing and choose the right lubricant. Periodic lubrication and careful alignment extend the service life of the unit.

When replacing a housing, it is common to find equivalent units from other brands with the same shaft size and similar mounting configuration. Interchangeability does not depend only on diameter: you must compare the center height, the hole spacing and the locking type. If the original housing has a different designation, the most practical approach is to send the complete part number and the main dimensions so that we can indicate the compatible alternative from SEALMASTER or another brand we supply.
