Industrial W231UL RA115-RRB COL Bearing Assembly

Industrial W231UL RA115-RRB COL Bearing Assembly is a mounted ball insert bearing from the Link-Belt RA-RRB family, featuring an eccentric locking collar (COL) for secure shaft retention. The insert accepts a 1-15/16 in bore (1.9375 in) and presents an outer diameter of 3.543 in, with a two-seal closure design to help protect lubrication and resist contamination in challenging environments. This medium-duty bearing insert is designed for quick mounting in compatible pillow blocks or housings and is commonly used in conveyors and other industrial machinery where reliable retention and easy assembly are important. The RA115RRB designation identifies the eccentric collar locking arrangement that enables fast, secure clamping on the shaft without additional disassembly, making it well-suited for applications requiring straightforward maintenance and durable operation in dusty or rugged settings.
