Industrial SFT-20R Bearing

The Sealmaster SFT-20R is a standard-duty, two-bolt flange-mounted ball bearing unit with a 1.25 in bore and a cast-iron housing, designed for fixed (non-expansion) mounting in industrial machinery. The insert uses 52100 bearing steel with a land-riding retainer and a felt labyrinth seal, relubricatable with lithium complex NLGI 2 grease, and it supports up to 5,450 rpm with a dynamic load capacity of 4,381 lbf and static capacity of 2,567 lbf. Its overall dimensions are 5.563 in long, 3.250 in wide, and 1.563 in high, with a 4.594 in bolt-center length and a 0.4375 in bolt size; weight is approximately 2.11 lb, making it a compact, robust option for standard-duty flange-mount applications where reliable lubrication and straightforward maintenance are priorities.
