Sealmaster FB-23T Flange Mount Bearing

The Sealmaster FB-23T Flange Mount Bearing is a non-expansion, standard-duty mounted ball bearing unit designed for compact installation in light‑industrial machinery. It features a 1-7/16 in bore and a three‑bolt flange, with a cast‑iron bracket that provides a rigid mounting base. Inside, a 52100 bearing steel insert rides on a high‑quality ball bearing, and a Skwezloc locking collar ensures precise, concentric drive alignment. The unit’s compact geometry delivers a 2-3/8 in bolt-center distance and an overall length/diameter of 3-3/4 in, with a 1/2 in depth and 6-1/8 in height, enabling straightforward integration where space is limited. Rated for up to 6,500 rpm, it supports dynamic loads up to 5,782 lb and static loads up to 3,493 lb, making it a robust choice for powered shafts and drive lines under moderate loads. A felt labyrinth seal with a flinger protects the bearing from contaminants while balancing grease retention with low friction wear. This FB-23T configuration is listed as uncoated in standard-duty catalogs, aligning with a typical, no‑frills mounting solution that favors reliability and long service life in environments that don’t require corrosion protection.
