SEALMASTER RPBA-CR series pillow blocks are mounted bearing units designed to support rotating shafts in industrial equipment. They consist of a bearing inserted in a cast iron housing that is bolted to the base. They are used in conveyors, fans, mixers and general machinery where robust support and stable alignment are required. MR Accesorios Industriales supplies this line as a brand throughout Argentina.

The RPBA-CR series designation is read in parts: RPBA identifies the pillow block family with mounted bearing; the number that follows indicates the shaft diameter in inches (for example, RPBA 103-C2 CR for a 1.3/16" shaft, RPBA 104-C2 CR for 1.1/4", RPBA 106-C2 CR for 1.3/8"). The -C2 suffix indicates the type of bearing-to-shaft locking, and CR indicates contact sealing. These codes allow selecting the exact unit according to diameter and mounting method.

In Argentine industry, these pillow blocks are used in belt conveyors, bucket elevators, mills, mixers and process equipment. Their robust construction makes them suitable for environments with dust, moisture or moderate loads. They are found in food, cement, chemical plants and in the agro-industrial sector, where mounting reliability is key to avoiding unplanned downtime.

To select the correct pillow block, take into account the shaft diameter, the type of load (radial, axial or combined) and the environmental conditions. The CR seal protects against contaminants and lubricant loss; verify that the bearing has adequate lubrication and that alignment between pillow blocks is precise to avoid parasitic stresses. Mounting must be done on a rigid, flat base, tightening the mounting bolts according to the manufacturer's recommendations.

SEALMASTER RPBA-CR series pillow blocks are interchangeable with other brands that follow the same standardized dimensions, although suffixes and tolerances may vary. When requesting a quote, provide the complete part number (for example, RPBA 108-C2 CR) and the operating conditions so we can offer you the equivalent alternative.
