Self-aligning ball bearings are double rows, self-retaining units comprising solid outer rings with a spherical raceway, inner rings with a cylindrical or tapered bore, ball and cage assemblies. The bearings are available in open and sealed types.

Because Those bearings generate less frictional, self-aligning ball bearings can accommodate higher speed than any other types of self-aligning rolling bearings. An exceptionally low minimum load requirement virtually eliminates sliding during start-up and light-load working conditions. This reduces the risk of bearing damage, improving reliability,extending bearing life and reducing maintenance costs.

This type of ball bearing is recommended when alignment of the shaft and housing is difficult and the shaft may flex. Pressed steel cages are usually used. Since the contact angle is small, the axial load capacity is low. The permissible dynamic misalignment is approximately 0.*7 to 0.*2 radius (4 to 7 degrees) under normal loads.
 

Deep groove ball bearing is simplest type of rolling bearings,biscally deep groove ball bearings are consisited of a outer ring,inner ring, cage and balls. these bearings are available of different structures as single row,double row,with metal shielded on both sides and rubber shielded on both sides etc.deep groove ball bearings are versatile because they are most widely used bearing. ZZ type deep groove ball bearings are designed for anti-dust and 2RS type of deep groove ball bearings are designed for protecting oil or greased leakage which can decrease bearings metenance cost and increase it's worklife, more deep groove ball bearings virants are designed for specific working conditions.

JKM bearing is a professional bearing supplier, as our vast experience of designing and manufacturing those bearings for domestic and oversea customers to meet their different requirements. Our deep groove ball bearings are used for diesel, agricultural machinery,power transimission parts, gearbox,etc.Because deep groove ball bearings are the most widely used bearing type, they are available from JKM in many designs, variants and sizes.
