Bearing Introduction

Bearing type

NACHI can produce products that can cover almost all mechanical industries, including robotic systems, lathes, tools, automobiles, large equipment, etc.



(1) Reduce friction and friction.

In the contact parts of the rings, rolling elements and retainers that make up the bearing, metal contact is prevented to reduce friction and wear.

(2) Extend fatigue life.

The rolling fatigue life of the bearing is prolonged when the rolling contact surface is well lubricated during rotation. Conversely, if the oil viscosity is low and the lubricating oil film thickness is not good, it will be shortened.

(3) Dissipate frictional heat and cool down.

The circulating oil feeding method can use oil to remove the heat generated by friction, or the heat transferred from outside to cool. Prevent overheating of bearings and prevent aging of lubricating oil itself.
