The SEALMASTER ERPBXT series housing is a pillow block mounted bearing, a unit that combines the bearing with its housing to secure rotating shafts to a flat base. It is used when the shaft needs rigid support and stable alignment in equipment where mounting is done on a horizontal surface. MR Accesorios Industriales carries this SEALMASTER line, a brand that MR carries, with more than 80 years of experience in the Argentine industrial market.

The ERPBXT series designation reads in blocks: the initial letters identify the pillow block housing family, and the numeric suffixes indicate the shaft diameter and the fastening type. For example, EPRBXT-303-4 corresponds to a housing for a 3 3/16 inch shaft with a four-bolt configuration. The final suffix indicates sealing or fastening variants within the same series. To request a quote, provide the complete code as it appears on the equipment.

These housings are used in belt conveyors, bucket elevators, mills, mixers, centrifugal pumps and process equipment in food, chemical, cement and aggregate treatment plants. In Argentina they are common in the oilseed, meatpacking and mining industries, where pillow block mounting simplifies installation on metal structures or concrete bases. Their design allows absorbing radial loads and some axial thrust depending on the internal bearing they incorporate.

To select the correct housing, take into account the shaft diameter, load type, rotation speed and environmental conditions. Check the sealing: in dusty or humid environments, additional protection is advisable. Check the alignment of the base and the tightening of the fastening bolts to avoid stresses on the bearing. Lubrication must follow the manufacturer's recommendation and be renewed according to the operating regime. If the equipment operates with vibration, check the internal clearance and the condition of the seals.

Pillow block housings have equivalents between brands: different firms offer units with similar mounting dimensions, but they are not always interchangeable without verifying the center height, the distance between holes and the shaft diameter. When replacing a housing, compare those dimensions and the internal bearing type. If you need a compatible alternative, write to us with the original code and we will indicate the option that best fits.

MR Accesorios Industriales carries the SEALMASTER line and also manufactures split plummer block housings, ANSI chains and pulleys. If you are looking for an ERPBXT housing or a variant that is not listed, send the code or model via WhatsApp and we will quote it promptly.
