Bower MG308-FFB Bearing

Bower BCA MG308-FFB is a Mast Guide Bearing (MG-series) designed for forklift mast assemblies, where it serves as the guide between the carriage and the rails to support heavy vertical loads while enabling smooth, controlled movement. The bearing features a bore of 1.5748 inches (40 mm) and an outer diameter of 4.0000 inches (101.6 mm), with inner and outer ring widths of roughly 0.9055 inches and 1.1250 inches, respectively, aligning with MG-series geometry. This FFB configuration is intended for MG-style mast-guide installations and is commonly used as the guide element in material-handling equipment, forklifts, and other industrial machinery that rely on precise mast guidance and durable performance. Users typically source this part as a direct-fit replacement in MG-series mast guides to maintain alignment, load capacity, and smooth carriage travel along the mast rails.
