Rexnord PLB6843FR Pillow Block Roller Bearing Unit

Rexnord Link-Belt PLB6843FR is a split-housed, four-bolt pillow block bearing unit designed for high-load duty shafts. It features a 2-11/16 in bore and a cast-iron housing that is adapter-mountable for flexible installation. Inside, it uses a Link-Belt spherical roller bearing (typically 22200LBK) with a triple-ring metal labyrinth seal to resist contamination and extend life; the unit is a fixed (non-expansion) bearing, relubricatable for maintenance. The base-to-center height is 3-1/2 in, and the bolt centers span 9-5/8 in to 11 in, providing compatibility with common conveyor and machinery mounting patterns. This PLB6843FR combination delivers robust support for rotating shafts in industrial drives, conveyors, and material-handling equipment where reliable, low-maintenance performance is required.
