Working principle of bearing production line

The working principle of the bearing production line mainly includes the following key steps:

Manufacturing of bearing rings: Firstly, the bearing rings are machined to the correct thickness using a lathe, and then the inner ring is inserted into the outer ring. Next, use a grinder to grind

the surfaces of the inner and outer rings into precise circles and ensure accurate diameters. During this process, use a water-soluble solution to avoid overheating of the bearing ring, as

overheating may cause deformation.

Grinding of inner and outer race raceways: Use a grinding machine with oily coolant to machine the outer diameter of the bearing into precise roundness and size, and the inner race and

raceways are also completed by similar machines

Polishing of bearing rings: Use a grinding stone machine coated with lubricating oil to polish the surface of the bearing ring until it shines brightly

Cleaning: Soak the stone grinding tool in oil and clean the bearing ring with kerosene

Manufacturing of ball bearings: Ball bearings are made of steel wire, which is cut into sections by a machine and then punched into rough balls using a punching machine, and then polished

and smoothed by a grinder. After hardening in the furnace, the ball bearings are cleaned with a cleaning agent and undergo quality inspection

Installation of retaining frame: The metal frame fixes the ball on the raceway. First, install half of the holder, then install the other half, and after passing the machine test, fully connect the two

holders together

Quality testing and assembly: Use a vibration and noise detector to check whether the bearings can work quietly, and unqualified bearings will be eliminated. Qualified bearings will be sent to

the automatic assembly machine, and the balls will be sent to the pusher through a hose. The pusher will push the correct number of balls into the raceway between the inner and outer rings

Laser engraving: Finally, qualified bearings will be sent to the laser machine for engraving, marking the model and number information. Through these steps, the bearing production line can

efficiently and accurately produce high-quality bearing products.
