22210K-C3 is a spherical roller bearing, 50 mm bore × 90 mm OD × 23 mm wide (1.9685 × 3.5433 × 0.9055 in). It has C3 internal clearance and a tapered bore (1:12).
The 22210K-C3 is a spherical roller bearing with a 50mm tapered bore (1:12 taper) designed to accommodate misalignment and heavy radial loads with moderate thrust loads in both directions. The C3 internal clearance provides greater radial clearance than standard, making it suitable for applications with thermal expansion or shaft deflection.
