GCr15 NTN Self-Aligning Ball Bearing 1310K Series With 50mm ID
Detailed Product Description
1. The self aligning ball bearings consist of two rows of balls and a common concave sphered raceway in the outer ring and the inner ring.
2. This type bearings have the self-aligning capacity which make the bearings insensitive to angular misalignments of the shaft relative to the housing.
3. The series of the bearings: 1200, 1300, 2200, 2300 and so on.
4. The bearings are also available with a cylindrical bore or, in certain size ranges, with a tapered bore
5. The bearings are particularly suitable for applications where considerable shaft deflections or misalignment are to be expcted
6. The self-aligning ball bearings have the lowest friction at high speed
This kind of ball bearings are particularly suitable for applications where considerable shaft deflections or misalignment are to be expected. Additionally, the self-aligning ball bearing has the lowest friction of all rolling bearings, which enables it to run cooler even at high speeds.
