Description

Description

A Guide ring always seals two surfaces. It is pressed against the cylinder wall and the groove flank by the pressure load and its inherent pre-loading force. PTFE Guide rings are self-clamping. Consequently, in most cases, there is no need to back the ring by a clamping spring.

Application & Usage

The function of a Guide seal is to guide the piston and piston rod of a cylinder, absorbing transverse forces. At the same time, it prevents metal-to-metal contact, optimizing the performance of the sealing system.

Materials used

Virgin PTFE, Bronze filled PTFE & Filled Grades of PTFE.
