SEALMASTER Flanged bearing unit square Skwezloc Locking Collar SF-31T

Overview

This Sealmaster SF-31T four-bolt flange ball bearing unit incorporates a powder-coated cast iron housing and 52100 bearing steel insert with black oxide finish. It employs Skwezloc concentric locking for precise alignment and felt labyrinth seals with flingers to shield against dry, dusty contaminants. The land-riding retainer design facilitates 360-degree grease circulation, supporting static misalignment up to ±2 degrees and relubrication through 1/8 NPT fittings.
