Working principle of bearing production line

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

Manufacturing of bearing rings: Firstly, the bearing rings are machined to the correct thickness, then the inner ring is placed into the outer ring, ground to the accurate thickness by a grinder, and

finally checked for thickness by a gauge.

Grinding of inner and outer rings: Separate the inner and outer rings and use different machines to grind their outer surfaces. The outer ring enters the grinder, which grinds its surface into a

precise circle and diameter, and avoids overheating with a water-soluble solution. After measurement, the bearing ring can only leave the grinder.

Grinding of inner and outer raceway: Use a grinding stone machine with oily coolant to machine the outer diameter of the bearing, and the inner and raceway 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 rings until they shine brightly

Cleaning: Soak the stone grinding tool in oil and then clean it with kerosene

Manufacturing of ball bearings: Ball bearings are made of steel wire, which is cut into sections by a machine and punched into rough balls using a punching machine. The protrusions on both

sides are cut off by a grinder, and then rounded and smoothed. After the ball is hardened in the furnace, it is cleaned with a cleaning agent and sent to the raceway between the inner and

outer rings after quality inspection.

Installation of retaining frame: The metal frame fixes the ball on the raceway. First, install half of the cage, then carefully install the other half of the cage. The machine rotates the bearing for

testing, and then fully connects the two cages

Solution spray cleaning and quality testing: The vibration noise detector checks whether the bearing can work quietly. Some bearings require lubricating oil, which is evenly applied to the

raceway by the machine. Finally, conduct quality testing and use an automatic control tester to eliminate bearings that do not meet weight requirements

These steps cover the entire process from raw materials to finished products, demonstrating the complexity and precision of bearing manufacturing. Each stage requires strict control and

testing to ensure the quality and performance of the final product.
