Hydraulic wipers, also known as scrapers, wiper seals or dust seals, remove dirt, sand, dust, moisture and other contaminants from the piston rod before it retracts into the hydraulic cylinder.
A properly functioning wiper helps prevent contaminants from entering the hydraulic oil and therefore protects not only the seals behind it, but also other components of the hydraulic system. Techniparts supplies hydraulic wipers in various profiles, materials, brands and dimensions, in both metric and inch sizes.
A hydraulic wiper is installed on the outside of the cylinder head around the piston rod. The wiper lip runs along the surface of the rod and removes contaminants as the cylinder retracts.
Without effective wiping, dirt particles can enter the cylinder via the piston rod. These contaminants can pollute the hydraulic oil and subsequently damage seals, guiding elements, pumps and valves.
The wiper forms the first barrier between the external environment and the internal sealing system. Proper wiping performance is particularly important for machinery operating outdoors or in contaminated environments.
The design of the mounting groove in the cylinder head determines which type of hydraulic wiper can be used. A design intended for a closed groove is not automatically suitable for an open bore. When selecting a wiper, it is therefore important to consider not only the dimensions and material, but also the groove design.
In a closed groove, the wiper is installed in a housing that is enclosed on both sides. Elastomer or plastic profiles are often used for this type of installation.
With an open bore, the wiper is pressed into the cylinder head from the outside. Designs with a metal core or metal casing are often used for this purpose to provide sufficient retention in the bore.
The drawings below illustrate the difference between an open groove, a closed groove and a closed groove for a double-acting wiper. The shape of the mounting groove is an important factor when selecting the correct wiper profile.
Most hydraulic wipers are designed primarily to remove contaminants and operate in combination with a separate rod seal. Combined designs are also available.
A conventional wiper removes contaminants from the piston rod as it retracts. Hydraulic pressure is sealed by a separate hydraulic rod seal.
A combination wiper combines wiping and sealing functions in a single profile. This can be particularly useful where installation space is limited. The condition of the piston rod and the operating conditions should be carefully considered when selecting this type of wiper.
Hydraulic wipers are available in various elastomers, plastics and material combinations. The appropriate material depends on factors such as wear, temperature, operating medium, speed and the level of contamination.
PU is widely used for hydraulic wipers because of its high wear resistance and good mechanical properties. It is suitable for many applications involving mineral-based hydraulic oils.
NBR is a cost-effective choice for general hydraulic applications and provides good resistance to many mineral oils and greases.
FKM/FPM, commonly referred to as Viton®, can be used where higher oil temperatures or improved chemical resistance are required.
PTFE offers very low friction and broad chemical resistance. Depending on the design, PTFE wipers can be energised by one or more O-rings.
For more demanding scraping applications, polyester or designs with a metal reinforcement or metal case can be used. Metal-cased designs are particularly suitable for installation in open housings.
The environment in which a hydraulic cylinder operates has a major influence on the choice of hydraulic wiper. Not every application requires the same wiping performance.
On excavators, agricultural machinery and cranes, the piston rod may be exposed to sand, mud, grit and moisture. A wear-resistant profile with effective wiping performance is important in these conditions.
In a relatively clean production environment, a highly aggressive wiping lip is not always necessary. A lighter profile can help reduce friction and wear on the piston rod.
A hydraulic wiper works together with the hydraulic rod seal. Both components should therefore be considered as part of a complete sealing system.
During extension, a very thin oil film remains on the piston rod. This lubricating film helps reduce friction and should be able to return towards the cylinder when the rod retracts.
If a wiper prevents the oil film from returning effectively, oil can accumulate between the wiper and the rod seal. This can result in pressure build-up between the two sealing elements and may eventually cause leakage.
For consistent operation, the piston rod must be guided correctly. Misalignment or side loads can cause the wiper lip to be subjected to greater loads on one side.
For recurring problems, the hydraulic guide rings and hydraulic guide strips should therefore also be inspected.
Scratches, corrosion, pitting or other damage to the piston rod can accelerate wear of both the wiper and the rod seal behind it.
Four important dimensions are generally required when selecting a hydraulic wiper.
The inside diameter (d) corresponds to the diameter of the piston rod along which the wiper lip moves.
The outside diameter (D) is determined by the groove or housing in which the wiper is installed.
The groove width (L) is measured in the longitudinal direction of the cylinder.
The overall height (h) represents the complete height of the wiper profile. For certain designs, the installation height may also need to be measured separately.
When measuring a worn or deformed wiper, it is preferable to measure the piston rod and mounting groove directly. Always specify whether the installation uses an open or closed groove.
A worn hydraulic wiper may no longer remove contaminants effectively from the piston rod and should therefore always be inspected during cylinder overhaul or maintenance.
Check for cracks, worn edges, cuts, hardening or deformation. A damaged lip may no longer make proper contact with the piston rod around its entire circumference.
If significant amounts of sand, dirt or other contaminants are found behind the wiper during disassembly, this may indicate that the wiping performance has been insufficient.
Hydraulic wipers are used in virtually every hydraulic cylinder where a piston rod extends outside the cylinder.
On excavators, cranes, aerial work platforms and earthmoving equipment, wipers protect hydraulic cylinders against sand, mud and other coarse contaminants.
Hydraulic wipers are also important in tractors, agricultural machinery and telescopic cylinders due to exposure to dust, soil and moisture.
Other applications include forklift trucks, lifting equipment, industrial presses, marine equipment and material-handling machinery.
Techniparts supplies hydraulic wipers from various manufacturers. Existing wipers can often be identified by their type number, material, profile and dimensions.
This makes it possible to find either an original type or a technically equivalent alternative for many existing machines. Cross-reference information can be used to compare type designations from different manufacturers.
For older machinery, inch sizes and non-standard grooves, custom hydraulic wipers can be produced. Where possible, provide the piston rod diameter, groove diameter, groove width, height, material and operating conditions.
Techniparts supplies wiper seals from various well-known brands. Below you will find an overview of brands, common types and materials. In addition to current product series, older type numbers have also been retained to make it easier to identify existing seals and machine components.

When overhauling a hydraulic cylinder, it is advisable to inspect not only the wiper but also the other sealing and guiding elements.
Hydraulic rod seals are used to seal the moving piston rod and help prevent hydraulic fluid from leaking out of the cylinder.
Hydraulic piston seals are used to separate the pressure chambers inside the cylinder.
Hydraulic guide rings and guide strips support and guide the moving components and help prevent unwanted metal-to-metal contact.
Most hydraulic wipers are designed primarily to remove contaminants and operate in combination with a separate rod seal. Combined designs are also available.
A conventional wiper removes contaminants from the piston rod as it retracts. Hydraulic pressure is sealed by a separate hydraulic rod seal.

When overhauling a hydraulic cylinder, it is advisable to inspect not only the wiper but also the other sealing and guiding elements.
Hydraulic rod seals are used to seal the moving piston rod and help prevent hydraulic fluid from leaking out of the cylinder.
Hydraulic piston seals are used to separate the pressure chambers inside the cylinder.
Hydraulic guide rings and guide strips support and guide the moving components and help prevent unwanted metal-to-metal contact.
A hydraulic wiper removes sand, dust, moisture and other contaminants from the piston rod before it retracts into the hydraulic cylinder.
The wiper keeps contaminants out of the cylinder. A rod seal helps prevent hydraulic oil from leaking out along the piston rod.
Common materials include PU, NBR, FKM, PTFE and polyester. The correct material depends on factors such as wear, temperature, speed, hydraulic fluid and contamination.

Yes. If the wiper prevents the oil film on the piston rod from returning effectively, oil can accumulate between the wiper and rod seal and may eventually leak out.
Important dimensions are the inside diameter (d), outside diameter (D), groove width (L) and height (h). Also specify whether the mounting groove is open or closed.
Replacement is recommended if there are cracks, hardening, wear, damaged lips or if significant amounts of dirt are entering the cylinder past the wiper.
