A bearing bush is a sliding bearing component that supports rotating shafts (such as pinion shafts, kiln supporting roller shafts, and mill shafts) under heavy load, low speed, and high friction conditions.

It provides a smooth, wear-resistant contact surface between the shaft and the housing, reducing friction and preventing direct metal-to-metal wear.

Produced according to the drawing confirmed by the user.
