Tapered roller bearing mounting method and heating installation points

If the inner ring of the bearing is tight with the shaft, and the outer ring is loose with the bearing housing, the bearing can be pressed into the shaft, and then the shaft will be installed into the bearing housing together with the bearing, and a soft metal casing (copper or soft steel) will be padded on the end of the inner ring of the bearing.

The role of rolling bearing seals and the types of common seals

Prevent the external dust, dirt, metal particles, moisture, acid gas and other debris invasion bearing internal. If the bearing seal is not good, the external debris invasion, so that the working condition of the bearing is significantly worse, the service life of the bearing will be significantly reduced.

What are the bearings that can withstand both radial and axial forces

In many mechanical equipment, bearings as a kind of rotating at the same time to provide load-bearing capacity of the parts, will often require to carry a certain direction of the load, and some times need bearings can simultaneously withstand radial and axial load

What are the methods of hardening bearings? How to prevent quenching deformation?

The purpose of bearing quenching is to improve the hardness, strength, wear resistance and fatigue degree of the bearing, and to obtain high dimensional stability and comprehensive mechanical properties through tempering

Factors affecting the fatigue life of bearing steel

The comprehensive sign of the intrinsic quality of bearing steel is fatigue life, some scholars put forward the view that: reducing the oxygen content still has not played a significant role in improving the fatigue life of bearing steel.

Several common defects in the forging process of bearing rings

Bearing rings in the forging process, due to bearing steel material defects, forging processing technology, processing equipment and human factors such as cracks, overburning, dents, forging folding and wet cracking and other defects, these defects can cause bearing damage, but also to the bearing life of the impact, resulting in early bearing breakage.
