Technopolymer bushing, Digidur Type M
Color code: grey 
Description
Didgidur Type M is a selflubricating bushing that works well in "dirty environments". When needed it can be reamed. Well suited for applications such as agricultural-, forest-, welding- and packaging-machinery etc. It is vibration dampening, suited for bushings exposed to shock-stress and/or edge-pressure.
