1. Characteristics of deep groove ball bearing

1.1 in structure, each ring of deep groove ball bearing has a continuous groove type raceway with a cross section of about one third of the circumference of the ball. It is mainly used to bear radial load, but also can bear certain axial load.

1.2 when the radial clearance of the bearing increases, it has the property of angular contact ball bearing and can bear the axial load of two directions alternating.

1.3 low friction and high speed.

1.4 simple structure, low manufacturing cost, easy to achieve high manufacturing accuracy.

1.5 generally, stamping wave type cage is used, and the bearing with inner diameter greater than 200mm or high-speed operation is made of vehicle solid cage.

There are more than 60 kinds of variable structure of deep groove ball bearing.
