22228K-C3 is a spherical roller bearing, 140 mm bore × 250 mm OD × 68 mm wide (5.5118 × 9.8425 × 2.6772 in). It has C3 internal clearance and a tapered bore (1:12).
The 22228K-C3 is a spherical roller bearing with a 140 mm tapered bore (1:12 taper) and C3 radial clearance. The tapered bore design allows for secure mounting on tapered shafts or adapter sleeves, while the C3 clearance provides greater internal clearance than normal to accommodate thermal expansion or shaft deflection.
