Sealmaster FB-12T Bearing

The Sealmaster FB-12T is a standard-duty three-bolt flange-bracket ball bearing unit with a 0.75 in bore, a powder-coated epoxy cast-iron housing, Skwezloc concentric locking for near-perfect concentricity, and a felt labyrinth seal with a flinger designed for dry, dusty environments. It uses a 2-012T bearing insert in 52100 bearing steel (black oxide), featuring a land-riding retainer that promotes 360-degree grease circulation around the rolling elements and Sealmaster's exclusive lock-and-pin dimple for direct lubrication and anti-rotation. Key dimensions include bolt-center-to-center length of 1.6875 in, overall length 4.1880 in, overall height 1.4500 in, housing width 2.3800 in, bore 0.750 in, and mounting bolt size 3/8 in, with a weight of 1.28 lb and static misalignment ±2.0°, while the unit is non-expansion (fixed) and rated up to 10,200 rpm with dynamic and static load ratings of 2,611 and 1,444 lbf. Operating temperature range is -20 to 220 °F, with a maximum of 220 °F, and lubrication uses lithium complex NLGI 2 grease.
