Technopolymer bushing, Digidur Type X
Color code: black 
Description
Didgidur Type X is a selflubricating bushing with unique abilities in operating with heavy loads, speed and also corrosion environments. Handles extreme temperatures and very heavy loads under longer periods of time. Well suited for heavy, grinding movements or high speeds or as a bushing in contact with corrosive substances . Type X is the roughest and toughest of all Digidur tecnopolymer bushings.
