Hydraulic Rod Wiper Seals or scraper seals are installed in the gland of hydraulic cylinders to prevent dirt, fluid or foreign particles entering the cylinder as the rod retracts back into the system. We stock a large range of metric and imperial rod wiper seal sizes in flexible profiles for snap grooves ad rigid profiles for open grooves in materials such as polyurethane, polyester, PTFE, NBR, FKM and Nylons.
The bearing ring, also known as a wear ring, guides the piston and rod of a hydraulic cylinder and prevents metal on metal contact which will damage these surfaces and subsequently lead to seal and component damage and fluid leakage.
Hydraulic Piston Seals (Piston Rings) are there to ensure fluids do not leak at the cylinder head as the pressure pushes the piston down. The hydraulic piston seals come in the form of single acting or double acting piston seals to provide the optimum seal for the cylinder being used. Typically made from PTFE or PU, a rubber/fabric composite or Polyester elastomer making it highly resistant to wear and can tolerate extremes in temperature.
Hydraulic Rod Seals, also known as Gland seals, Headbush or Neck seals and are the most important part of any fluid power equipment which prevents leakage of fluid from within the cylinder to the outside. The hydraulic rod seals are available in rubber, PU, PTFE, fabric reinforced elastomers and plastic.
