Rubber & PU Seals
Wiper seals
Product detail:-
Wiper seals (also known as scraper seals or wiper scraper seals) are axial seals that form a tight fit while still allowing a reciprocating ram rod to pass through the seal’s inner bore. Wiper seals are commonly installed in hydraulic cylinders to scrape dirt, chips or moisture from the piston rods as they retract into the system. Thus, they prevent any contamination that could potentially damage wear rings, piston seals and other components further inside the system.
All profiles are standard machined wiper seals. We can produce virtually any profile in any dimension.
Product description
AO1-B
Hydraulic, single acting
Wiper with interference fit on outside diameter, providing a technically accurate closure at the cylinder. Wiping edge assures a reliable protection against penetration of dust and dirt whilst allowing backflow of residual oil film. Without Back support area.
AO2-B
Hydraulic, single acting
Wiper with interference fit on outside diameter. Wiping edge assures a reliable protection against penetration of dust and dirt whilst allowing backflow of residual oil film.
AO3-A
Hydraulic, single acting
Wiper with mounting cage for press-fit installation into axially open housings. Wiping edge assures a reliable protection against penetration of dust and dirt, the use of plastic mounting cages avoids corrosion in the press-fit for housings .
AO5-A
Pneumatic, single acting
Wiper with interference fit on outside diameter. Special design of wiping lip allows. Retention of initial lubricating film. Back support area prevents tilting of wiper.
AO7-A
Hydraulic, single acting
Wiper to fit in angled housings (300 angles).design mainly used in British equipment, in inch as well as metric dimensions.
AO8-A
Hydraulic / pneumatic, single acting
Wiper usually fixed in housing with clamp flange. Mainly used for replacement in old hydraulic and pneumatic cylinders of for secondary applications.
A11-A
Hydraulic / pneumatic, double acting
Wiper including additional sealing lip used in combination with O-ring activated PTFE seals (tandem) to reduce residual oil film. It is also used as complete solution for pneumatic application in small diameter range. Max.allowed pressure load 1 6 bar (230 psi)
