Processing Process Steps of Deep Groove Ball Bearings

What is deep groove ball bearing
Deep groove ball bearings, formerly known as single-row centripetal ball bearings, are the most widely used rolling bearings. It is characterized by small friction resistance, fast speed, can be used to bear radial load or radial and axial simultaneous action on the mechanical combined load, can also be used to bear axial load.

Characteristics of deep groove ball bearings
Deep groove ball bearing is the most commonly used rolling bearing. Its structure is simple and easy to use. Mainly used to bear radial load, but when the radial clearance of the bearing is increased, it has the performance of a certain angular contact ball bearing, and can bear radial and axial combined load. In high speed and should not be using thrust ball bearing, could also be used to carry pure axial load. With deep groove ball bearing size is the same the other types of bearings, such bearing small friction coefficient, high limit speed. But don't impact resistance, not suitable for carry heavy load.

Processing process steps of deep groove ball bearings
1.Processing of tube billet: the bearing steel is heated to 1150℃ ~ 1200℃ in a heating furnace, and the heated tube billet is perforated with a perforating machine to produce capillary tubes.
2.Spheroidizing annealing: the capillary is spheroidized annealing, after annealing, the hardness range of the capillary is HRB88 ~ 94.
3.Hot rolling of tube billet: send the annealed tube into the heating furnace for secondary soaking; After the second soaking, the capillary tube is rolled to form a waste pipe by reducing diameter, reducing wall and extending.
4.Pipe blank shaping and cutting: the pipe passes through the sizing unit for sizing and shaping, and then straightening and cutting to form the set.
5.Recrystallization annealing: the kit is recrystallization annealing treatment, eliminate work hardening, so as to facilitate the implementation of cold rolling.
6.Soft grinding kit: first soft grinding the double end faces of the kit, then soft grinding the outer circle of the kit, first grinding the double end faces, and then grinding the outer circle. The outer circle is a through-through grinding, and the material is bonded together through the end faces for processing, to ensure that the outer diameter surface of the parts is always on the same plane with the bracket.
7.Kit hole: drill stop plug hole and oil hole on the surface of the kit, rough the inner hole surface of the kit, to prepare the inner hole surface of cold rolling.
8.Cold Rolling Kit: For cold rolling of deep groove ball bearing ring raceway, there are 6 stage speed of core roll feed in the cold rolling process, the speed range is 0.4mm/s ~ 1.0mm/s.
9.Turning suite, suite for chamfering, seal groove.
10.Precision grinding kit: precision grinding kit to improve the surface precision of the kit.
11.Bearing installation: put the ball between the rings, install the cage, inject grease, install the seals, and complete the assembly of the deep groove ball bearing.
