Excavator Du Bushing

Product Overview

Description

Feature

1).Good load capacity and anti-wear.

2).It is in high load capacities and low speed with rotational,oscillationg or frequent stop-start motion.

3).It can work for a long time without oil in the condition of boundary lubrication,under oil or grease lubrication interval, the working-life will be longer.

4).It is machinable for the thicker of PTFE.
