NSK 2311 Self-aligning ball bearing

Part no. 2311 ball bearing, which provided by Japan NSK Factory, self-aligning ball bearings, which has two rows of balls and a common concave spheroid raceway in the outer ring. The bearing is consequently self-aligning and insensitive to angular misalignments of the shaft relative to the housing. Therefore the NSK bearings are particularly suitable for applications where considerable shaft deflections or misalignment are to be expected.

Following is the main data of NSK self-aligning roller bearings 2311:
