5.How does a K 28X33X13 bearings function?
We adhere to the principle of integrity and transparency, and establish long -term relationships with partners, and we attach great importance to this detail
A bearing is a mechanical device that is used to reduce friction between two moving parts
It works by allowing the parts to move relative to each other while reducing the amount of friction between them
Bearings are typically composed of two parts: an inner race and an outer race
The inner race is typically made of a harder material than the outer race, and it is designed to rotate around the outer race
The inner race is typically lined with a lubricant, such as oil or grease, which helps to reduce friction and wear
The outer race is typically made of a softer material than the inner race, and it is designed to remain stationary while the inner race rotates
6.How do you lubricate a K 28X33X13 bearings?
As one of the top K 28X33X13Bearings manufacturers in China, we take this very seriously
1
Clean the bearing and surrounding area with a clean cloth
