How to make hydraulic pump bearings?

Do you know how the hydraulic pump bearings are made? Friends who want to know, please see the following analysis for everyone:
The specific production process of hydraulic pump bearings: raw materials-inner and outer ring processing, steel ball or roller processing, cage (stamping or solid) processing-bearing assembly-bearing finished products.
In the production process of hydraulic pump bearings, the key are the following links:

1. Forging process
Forging is an important part to ensure the reliability and life of the hydraulic pump bearings. After the raw materials are forged, the bearing ring blank is formed. At the same time, the organizational structure of the raw material becomes denser and the fluidity becomes better, which can improve the reliability and service life of the bearing. In addition, the quality of the forging process will directly affect the utilization rate of raw materials, which will have an impact on production costs.

2. Heat treatment
The heat treatment process is to forge and turn the hydraulic pump bearings ring after high temperature treatment, which directly affects the uniformity of carburization in the bearing ring, can improve the wear resistance and hardness of the bearing, and also affects the reliability and life of the bearing Important link.
3. Grinding process
The hydraulic pump bearings ring after heat treatment also needs to be ground, which is an important link to ensure the accuracy of the bearing. After grinding, the production process of the bearing ring is basically completed. Bearing inner and outer ring process flow: bar-forging-turning-heat treatment-grinding-super-finishing-parts final inspection-anti-rust storage.

The main production equipment includes: cold rolling machine, automatic ball bearing internal grinder, quenching line, annealing furnace, press, CNC lathe, bearing grinder, inner groove grinder, outer groove grinder, high precision horizontal shaft round table surface grinder, CNC Milling machine, centerless grinding machine, high-precision through-grinding centerless grinding machine, accurate channel superfinishing machine, internal surface CNC grinding machine, CNC reciprocating double-end surface grinding machine, high-temperature high-speed bearing testing machine, heat treatment production line and quality inspection equipment.
