21315K-C3 is a spherical roller bearing, 75 mm bore × 160 mm OD × 37 mm wide (2.9528 × 6.2992 × 1.4567 in). It has C3 internal clearance and a tapered bore (1:12).
The 21315K-C3 is a spherical roller bearing with a 75mm tapered bore (1:12 taper) and C3 radial internal clearance. The tapered bore design allows for secure mounting directly onto tapered shafts or adapter sleeves, while the C3 clearance provides greater internal clearance than standard for applications with thermal expansion or shaft deflection.
