Rexnord GRA111-RRB Bearing

Timken’s Fafnir GRA111RRB eccentric locking collar ball insert bearing is a mounted bearing insert designed for pillow block and two-bolt flange-housing assemblies. It features a cylindrical bore of 1-11/16 in (42.86 mm) and an outer diameter of 85 mm, with a wide inner ring that helps distribute loads across the inner race for improved stiffness. The unit includes two rubber seals (RRB) and is re-lubricatable, enabling maintenance-friendly servicing and extended lubrication intervals. Clamped on the shaft by an eccentric locking collar, it provides quick, secure mounting without additional fasteners and supports reliable operation in constrained spaces. This GRA111RRB insert is used in power transmission and conveying equipment and other industrial machinery where compact, robust mounted bearings are required, delivering consistent rotation under typical radial and axial loads and contributing to longer service life in demanding environments.
