NSK deep groove ball bearing is simple in structure and easy to use and maintenance. It is mainly used to bear radial load and also to bear a certain axial load. When the radial clearance of bearing increases, it has the performance of angular contact ball bearing, which can bear large axial load. The friction coefficient of the bearing is small, the limit speed is high, size range and form. The changes are varied.
The deep groove ball bearing with dustproof cover and sealing ring has been filled with the right amount of grease. It should not be heated or cleaned before installation. It does not need to lubricate in the process of operation. It is suitable for running temperature between -30 and +120 C.
