Sealmaster SF-23 Flange Bearing Four Bolt Assembly

Sealmaster SF-23 four-bolt flange bearing assembly is a standard-duty mounted radial ball bearing in a cast-iron housing designed for reliable shaft support in compact installations. It accepts a 1-7/16 in bore (1.4375 in), and the four-bolt flange provides secure mounting to a support surface while the setscrews lock the shaft in place. The bearing insert uses 52100 bearing steel, offering high wear resistance, and the housing is finished with a black oxide coating for corrosion resistance. A lock pin and dimple support anti-rotation and streamline lubrication, while a felt labyrinth seal helps protect the bearing from dust and debris and helps retain lubrication. The overall unit length is 4-19/32 in, making it suitable for spaces with limited clearance. This SF-23 flange unit is used in industrial machinery where a compact, robust flange-mounted bearing supports rotating shafts.
