Causes of Noise Generation at Maximum Rotational Speed in Rolling Bearings

2026-01-12

The causes of noise in deep groove ball bearings are complex. One factor is wear on the mating surfaces of the inner and outer rings. This wear disrupts the alignment between the bearing and housing, or between the rolling elements and shaft, causing axial displacement.

What are the specific characteristics of maintaining rolling bearings?

When design reference surfaces become excessively deformed and unusable, alternative surfaces must be selected as references, necessitating the reorganisation of dimensional chains. For instance, if the bearing housing exhibits significant deformation, the rotating assembly should serve as the reference.

How to prevent grease from being flushed out of bearings?

2026-01-12

Bearing dust covers and seals serve as vital barriers protecting the internal grease within bearings. They effectively prevent external particulates from entering while retaining the lubricant.However, different seal types exhibit varying levels of protection

What factors affect bearing service life?

2026-01-12

Whether in terms of installation or operational maintenance, numerous external factors can impact the service life of rolling bearings, such as improper installation or inadequate maintenance. Let us share the common factors that influence bearing longevity.

Purpose of Bearing Preload and Methods of Bearing Preload Direction

2026-01-12

Bearing preload refers to the process of generating an initial pressure and pre-deformation between the rolling elements and the inner/outer rings during bearing installation. This ensures both rings remain in a compressed state, enabling the bearing to operate under negative clearance when subjected to working loads.
