Technopolymer bushing, Digidur Type D
Color code: blue 
Description
Didgidur Type D is ideal as a bushing in applications in direct contact with fluids. It has a very low absorption point. Type D is very similar to Type H. It is better in price, but has less loadcapacity compared to Type H. Pricewise a very good bushing to applications where low friction or high rotating speed is important. Type D is capable of handling relatively high speeds at low- to medium- loads. Type D is a selflubricating bushing.
