CC2——cylindrical roller bearing (not interchangeable) radial clearance, which is smaller than the standard Huai clearance. CC——Cylindrical roller bearing (not interchangeable) radial standard clearance. CC3——Cylindrical roller bearings (not interchangeable) radial clearance, which is larger than the standard Huai clearance. CC4——cylindrical roller bearing (not interchangeable) radial clearance, which is larger than CC3 clearance. CC5——cylindrical roller bearing (not interchangeable) radial clearance, which is larger than CC4 clearance. MC1 - small and medium-sized, miniature ball bearing radial clearance, smaller than MC2 clearance. MC2 - small and medium-sized, miniature ball bearing radial clearance, smaller than MC3 clearance. MC3——Small and medium-sized, miniature ball bearing radial clearance standard Huai clearance. MC4——Small and medium-sized, miniature ball bearing radial clearance, which is larger than MC3 clearance.
