Technopolymer bushing, Digidur Type G
Color code: grey 
Description
Didgidur Type G is a selflubricating "universal bushing", well suited for most applications in most branches. Price- and quality-wise an excellent "allround-bushing" for applications where strength and resistance is required. Type G has low friction coefficient. Is capable of handling relatively high speeds where you have medium- to heavy- loads.
