Technopolymer bushing, Digidur Type P
Color code: black 
Description
Didgidur Type P is a sleflubricating bushing well suited for radial movements with heavy loads. Excellent for applications demanding low fluid absorption, high pressures or high speeds with medium loads. The friction coefficient drops as the load increases. Best used for applications with low- to medium-loads.
