Rexnord Link-Belt ER22K-MHFF Unmounted Ball Bearing

Rexnord Link-Belt ER22K-MHFF Unmounted Ball Bearing is a straight-bore, unmounted bearing in the Link-Belt family, designed for precision alignment in light- to medium-duty applications where a separate mounted housing is not included. It features a 1-3/8 in bore (1.375 in), an outside diameter of 2.8346 in, and a width of 3.0000 in, delivering a compact footprint suitable for space-constrained machinery. The ER22K-MHFF designation identifies this component as a specific unmounted bearing option within Rexnord’s Link-Belt lineup, built around a ball insert configuration to support smooth rotational motion. A Centrik-Lok locking device provides secure, concentric collar engagement, helping maintain shaft alignment during operation. Lubrication is pre-filled to 10% grease, offering initial lubrication at installation. This part reflects Rexnord’s emphasis on interchangeability within the Link-Belt family, making it a precise choice for engineers who require an 1-3/8" bore unmounted bearing with established Rexnord performance characteristics.
