Bushing Bearings

Bushing Bearings

Bushings are designed with a low coefficient of friction, good wear resistance, corrosion resistance, and self-lubricating properties. It provides better self-lubrication, hard weariness, and low friction. Benefits of bushings include a low coefficient of friction, compact dimensions, low noise, corrosion resistance, and self-lubricating properties.

Linear Bearings

Linear Bearings

The linear bearing, an essential component in bearing manufacture, is designed to rotate with the steel ball, enabling it to function within the linear motion system as a linear motion mechanism. It exhibits small friction and relative stability while maintaining high accuracy, low noise, and high rigidity even under heavy load.
