22309K-C3 is a spherical roller bearing, 45 mm bore × 100 mm OD × 36 mm wide (1.7717 × 3.937 × 1.4173 in). It has C3 internal clearance and a tapered bore (1:12).
The 22309K-C3 is a spherical roller bearing with a 45 mm tapered bore (1:12 taper) and C3 radial clearance. The tapered bore design allows for mounting directly on tapered shafts or on cylindrical shafts using adapter sleeves or withdrawal sleeves. The C3 clearance provides greater internal clearance than standard, accommodating thermal expansion and shaft deflection.
