21312K is a spherical roller bearing, 60 mm bore × 130 mm OD × 31 mm wide (2.3622 × 5.1181 × 1.2205 in). It has a tapered bore (1:12).

The 21312K is a spherical roller bearing with a 60 mm tapered bore (1:12 taper) from the 213 series. Spherical roller bearings feature two rows of barrel-shaped rollers running on a common spherical outer ring raceway, allowing them to accommodate misalignment and deliver high radial and moderate axial load capacity.
