22230-K-C3 is a spherical roller bearing, 150 mm bore × 270 mm OD × 73 mm wide (5.9055 × 10.6299 × 2.874 in). It has C3 internal clearance and a tapered bore (1:12).
The 22230-K-C3 is a spherical roller bearing with a 150mm bore diameter, featuring a tapered bore (1:12 taper) and C3 radial internal clearance. The tapered bore design allows for mounting directly on tapered shafts or adapter sleeves, while the C3 clearance accommodates thermal expansion and shaft deflection in demanding applications.
