When assembling rolling bearings, the clearance should not be too large or too small. The large clearance will cause the number of rolling bodies bearing loads at the same time to decrease, so that the load of a single rolling body increases, thus reducing the rotation accuracy of the bearing and ...

Lubrication and Surface FinishesRolling contact bearings have to be lubricated in addition to having exceedingly good surfacefinishes.The life of a rolling element bearing depends to a large extent on the smoothness of thecontacting surfaces – the balls, rollers, and races. Typical surface ro...

Many bearings require periodic maintenance to prevent premature failure, but many others require little maintenance. The latter include various kinds of polymer, fluid and magnetic bearings, as well as rolling-element bearings that are described with terms including sealed bearing and&nb...

Capture these ten points to ensure a longer service life of the bearing cage1. Poor bearing lubricationWhen the bearing is running in the state of lean oil, it is easy to form adhesive wear, which deteriorates the working surface. The tear caused by adhesive wear is easy to enter into the cage, ...

The characteristics and differences of quenching crack, forging crack and grinding crack, the causes of quenching crack formation and how to prevent it, let's take a look with Xiaobian.Quenching crack is a common quenching defect, which is caused by many reasons.Because the defect of heat tr...

(1) Reason: bearing accuracy is lowMethod: use the specified precision grade bearings(2) Cause: The spindle is bent or the box hole is not concentricMethod: Repair the spindle or case(3) Reason: The belt is too tightMethod: Adjust the belt so that the fit is appropriate(4) Reason: Poor l...

Large spherical roller bearingBasic definitionSpherical roller bearing is in the two groove of the inner ring and outer ring raceways between spherical bearing assembly, a drum shaped roller.Basic speciesFolding roller bearingSpherical roller bearings are divided into: cylindrical hole, tapere...

The so-called bearing clearance, that is, when the bearing is not installed in the shaft or bearing box, the inner ring or outer ring side fixed, and then not fixed side of the radial or axial movement of the amount of movement. According to the direction of movement, can be divided into radial cl...
