Technopolymer bushing, Digidur Type H
Color code: grey 
Description
Didgidur type H is a selflubricating bushing well suited for underwater applications or applications in permanent contact with fluids. Type H can also be used where there are demands for good thermal conductivity against high temperatures. Digidur type H has very good anti-corrosion abilities as well as low friction coefficient.
