Sealmaster FB-12 2-Bolt Flange Bearing Cast Iron Housing

Sealmaster FB-12 is a cast-iron flange-mount ball bearing unit with a 3/4 in bore and a three-bolt flange. The solid cast-iron housing supports a 52100 bearing steel insert and employs a felt labyrinth seal for standard-duty, non-expansion (fixed) operation, providing reliable, low-friction performance in fixed-mount applications. The flange pattern offers a 2-3/8 in bolt-center-to-center spacing and an overall length of 1-1/2 in, contributing to a compact footprint suitable for tight installations. Rated for up to 7,300 rpm, it supports dynamic loads around 2,611 lb and static loads around 1,444 lb, and operates over a temperature range from -20 to 220 °F. The unit uses set-screw locking to secure the shaft and is designed for rugged service in equipment where a sealed, cast-iron housing flange bearing is required.
