Hydraulic Wiper Seals
Hydraulic cylinders are used in a wide range of applications and environments, including those with dust, debris, or extreme weather. Wiper seals (also called as scrapers, excluders, or dust seals) are installed on the exterior surface of the cylinder head to prevent pollutants from entering the cylinder assembly and hydraulic system.
When the equipment is stationary (no reciprocating motion of the piston rod) and in operation (dynamic, reciprocating rod), hydraulic wiper seals maintain sealing contact with the piston rod, whilst the rod seal determines the rod diameter d tolerance. The retracting piston rod might convey impurities into the cylinder without a wiper seal.
The wiper seal's outer static sealing within the housing is also critical to prevent moisture or particles from penetrating around the wiper seal.

Double Acting Hydraulic Wiper Seal - WS-D14
Double Acting Hydraulic Wiper Seal - WS-D14 DESCRIPTION Double Acting Hydraulic Wiper Seal - WS-D14 acts with a wiping function of a U-ring, and a wiping action outwards against soiling. Strong wiping action against dirt Very good sealing effect against residual film of oil on the extending rod Wear-resistant The double-acting design offers optimum contamination resistance while also maximizing performance in conjunction with the rod seal. To prevent..
Double Acting Hydraulic Wiper Seal - WS-D15
Double Acting Hydraulic Wiper Seal - WS-D15 DESCRIPTION Double Acting Hydraulic Wiper Seal - WS-D15 acts with a wiping function of a U-ring, and a wiping action outwards against soiling. The WS-D15 is a double-acting double wiper that prevents foreign particles from entering hydraulic cylinders. The lip is built in such a manner that it reliably sweeps away dirt while leaving an oil film on the rod. The second lip serves a dual purpose, removing debris..
Single Acting Hydraulic Wiper Seal with metal case - WS-20
Single Acting Hydraulic Wiper Seal with metal case - WS-20 DESCRIPTION This is a single-acting wiper. Because it is pressed against the rod, dirt is wiped from the surface by the action of the rod as it retracts. On the outer diameter, a metal caged ring is vulcanized onto the elastomer body. These hydraulic wipers are made from a hard nitrile material chemically bonded to a corrosion-resistant carbon steel shell. As with other press-in wipers, there is no need for addi..
What are the primary functions of hydraulic wiper seals in hydraulic systems?
The primary function of hydraulic wiper seals is to prevent contaminants such as dirt, dust, and debris from entering the hydraulic cylinder assembly. They ensure that the internal components of the hydraulic system remain clean and functioning optimally, thereby extending the lifespan of the equipment. For instance, the Single Acting Hydraulic Wiper Seal - WS10 is designed specifically to perform this function effectively.
How do the materials used in hydraulic wiper seals affect their performance?
The materials used in the manufacturing of hydraulic wiper seals greatly influence their durability and effectiveness. High-quality materials can withstand extreme temperatures and pressures while maintaining flexibility and resilience. For example, the Single Acting Hydraulic Wiper Seal with metal case - WS-20 offers enhanced stability due to its metal casing, making it suitable for more demanding applications.
What should be considered when selecting hydraulic wiper seals for specific applications?
When selecting hydraulic wiper seals, factors such as the operating environment, pressure levels, and temperature ranges must be considered. Additionally, the type of hydraulic system (single or double acting) will dictate the appropriate seal design. For instance, for double-acting systems, products like the Double Acting Hydraulic Wiper Seal - WS-D14 are recommended to ensure optimal performance.
