GUIDE RINGS

DMR offers an expansive range of guide rings to the design engineer and repairer where the prevention of metal-to-metal contact and low frictional loss in hydraulic fluid power and pneumatic sealing systems is critical. 

Guide Rings are referred to under many different names, Bearing Rings, Wear Rings, Slip Rings and Wear Strips, but they all have the same task of guiding pistons and rods in hydraulic and pneumatic cylinders and preventing metal-to-metal contact of the hardware components in the system. 

The correct choice of guide ring can ensure trouble free service and prolonged seal life. If you have a problem with misalignment, contamination in the hydraulic system through metalwork contact or are looking for a guide ring to withstand high radial bearing load, offer low friction, work at high temperature or all of these requirements together, contact our technical department for advice.

DMR manufactures high quality precise tolerance guide rings from a variety of high performance materials such as Lubricated Polyester fabric Laminate (often referred to as Phenolic), Polyacetal, Lubricated Nylons, PEEK, Various PTFE’s and Polyimide.

IMPORTANT - Please Note: The data shown below are maximum values and operating ranges and cannot be used at the same time.

For example: The maximum operating speed will depend on material type chosen, working pressure, application temperature and clearance gap values.  The temperature range shown is also dependent on choice of material and media to be sealed.
