Bearing ring

Including bearing inner race and outer race, the bearing steel with low oxide and high purity is adopted, which greatly improves the hardness of the bearing.

Rollers

High precision steel ball, which greatly transfers the load between the bearing inner race and outer race

Holder

Optimize load and reduce friction heat

Integral seal

Keep the bearing grease to reduce foreign matters entering the bearing

Bearing fit mode

There are three types of fits: clearance fit, interference fit and transition fit

Clearance fit:

The small hole of the shaft is large, and there is a tolerance gap between the shaft and the hole (shaft<hole, loose fit)

Interference fit

(Shaft ≥ hole, tight fit) means that the shaft is large and the hole is small, and the fit is very tight

Transition fit:

It refers to the whole axial length of shaft and hole, some are clearance fit, some are interference fit. The whole fit is tight (tight fit)

Bearing steel, steel grade GCR15, hardness 60-62: vacuum degassing treatment, high purity, low oxygen content

It is the most commonly used bearing material in the market, with high comprehensiveness

Stainless steel stainless bearing steel contains magnetism: it has rust prevention and corrosion resistance in special use environment, and the price is high

The hardness of high carbon steel is 50-55 °: the wear resistance is general, the noise is high, and the most important feature is low price. It is generally used for products with low requirements. The bearings made are of high performance and high precision
