2300 Series

The components of the self aligning ball bearing include two rows of balls, a cage, an inner ring, and an outer ring with a common concave sphered raceway.This type of bearings is self-aligning and insensitive to angular misalignments of the shaft relative to the housing. The bearings are produced in several design: open bearings with the basic design, sealed bearings, open bearings with an extended inner ring.The self alignning ball bearings have the lowest friction of all rolling bearings.The bearings are available with a cylindrical bore or with a tapered bore in certain size ranges.
Suffix definitions of Self-aligning ball bearings:
C3: radial clearance than ordinary clearance
K: 1/12 taper tapered bore
K30: 1/30 taper tapered bore
M: Ball guided machined brass cage
2RS: with both ends of closures
