Technopolymer bushing, Digidur Type A
Color code: white 
Description
Didgidur Type A is a selflubricating bushing that ideal for applications in contact with foodstuff or medical handling. The material has good abilities for embedding foreign particles. It is also a "quiet running material" with low friction coefficient. Best suited for slow movements and low- to -medium- loads.
