Description
Structural Design:
HW seals are snap-in wiper seals and have a double-lip design with an internal-facing wiper lip that regulates the lubrication film on the rod.
The internal lip wipes any excess fluid film from the rod on the extending stroke and allow this excess fluid to return under the rod seal on the retracting stroke. Double-acting wipers, therefore, improve the performance and extend the service life of rod sealing systems.
SKF recommends using double-acting wiper seals in combination with U-cup rod seals with a single-lip design, such as PTB, to safeguard pressurized fluid can return to the hydraulic system.
Summary of Advantages:
- Good wiping performance on the rod with double wiper design
- No twisting in the grooves
- Twins lip ensures drier sealing
- No twisting in the housing
Typically made from polyurethane, alternative materials can be provided upon request to suit your specific needs.
