Introduces a ball bearing inner and outer ring and ball materials?
Ball bearing inner and outer ring and ball materials: ball bearings in normal use, the roll channel slot part of contact with the ball to repeatedly under extreme pressure of 1000 mpa, to bear such a high stress, and repeatedly asked long life, so the kinds of material, purity, hardness becomes a very important factor.
Company mainly adopts high chromium bearing steel, corrosion resistance, good markov system column stainless steel as the material of inside and outside the ring and ball.
Chromium bearing steel with advanced vacuum degassing performance chromium bearing steel (
JISG4805 / SUJ2 AISI / SAE52100)
As well as steel.
Because to ensure the quenching hardness, so the load resistance, durability, the noise characteristics are good.
Stainless steel material with company development 'DD400' material alone, than SUS440C, its high quenching hardness, long service life, good resistance to load.
In addition, due to the materials of carbon spheres, fine distribution and its noise characteristics similar to chrome steel.
According to the ASTM -
A380 standard test results, the corrosion resistance is the same as the SUS440C.
In addition, with high performance processing for office automation equipment in recent years and diffusion, in office automation equipment used in a lot of HDD spindle motor parts, such as ball bearing in these parts occupies very important position, the stand or fall of bearing characteristics of this kind of device characteristics of good or bad plays a decisive role.
In order to adapt to this situation, the company developed a new material 'MKJ3' and its production process.
This material has good load resistance and good impact, the advantages of sound performance is the same.
