1. Installation Recommendation

DBM/TPM is a double acting sealing and guiding element, Consisting of an elastomer, two back-up rings and two guide rings. Dynamic and static properties of the elastomer play a good sealing role, The back-up ring prevents the elastomer from being squeezed into the sealing gap, the function of the guide ring is to guide the piston in the cylinder and absorb the radial force. The sealing is mainly used for piston and hydraulic cylinder, such as bulldozers, excavators, loaders, hydraulic gates and agricultural machinery.

Guide ring: filled PTFE / PA

Back-up ring: TPU polymer

Elastomer: NBR
