The Timken Company 1100KRRB Ball Insert Bearing

The Timken 1100KRRB ball insert bearing is a cylindrical-bore, wide inner ring insert bearing designed for mounted bearing housings with spherical outer diameters and a two-set-screw locking arrangement at 90° spacing, suitable for pillow block bearings and flange units. Its bore diameter is 1.0000 in (25.4 mm) and outside diameter 2.0470 in (52.0 mm), with an overall width of 1.748 in (44.4 mm) and inner/outer ring widths of 1.375 in (34.92 mm) and 0.591 in (15.0 mm). This Timken Fafnir part is factory lubricated and non-relubricatable, made from bearing steel, and uses a shroud seal to protect the bearing in industrial environments. With a dynamic load rating of 3,490 lbf (15,500 N) and a static load rating of 1,760 lbf (7,800 N), it supports conveyors, agricultural equipment, packaging machinery, food processing equipment, industrial fans, and other material handling systems that require dependable shaft retention in mounted bearings with spherical bores. Common replacements include SKF YAR 205-2F, NTN UC205, and NSK UC205.
