Wiper seals protect hydraulic cylinders from dirt and fine particles and are essential for the operational reliability of the sealing system. They effectively remove contamination from the piston rod and extend the service life of both seals and components.

At STEFFCA, you will find wiper seals designed for demanding applications with high requirements for wear resistance, temperature performance and reliable operation.


Effective protection of hydraulic systems
Wiper seals prevent dirt and particles from entering the cylinder. Even small amounts of contamination can lead to increased wear and unplanned downtime. STEFFCA’s wiper seals ensure:

  • Effective removal of dirt and particles

  • Protection of internal sealing components

  • Reliable performance at varying speeds


Materials and performance
The range includes:

  • Polyurethane (TPU) – high wear resistance

  • Rubber (NBR and FPM) – adapted to temperature and operating environment

  • PTFE bronze with O-ring (NBR/FPM) – for high-speed applications (up to 5 m/s)

  • Metal-reinforced designs – for secure retention in open grooves

  • Temperature ranges from -40 °C to +110 °C, and up to +200 °C with FPM.


Solutions for different groove designs
Wiper seals are available for:

  • Open grooves (with metal case)

  • Stepped grooves (without metal case)

Additional options include:

  • Single- and double-lip designs (double lip minimises residual oil film)

  • Recessed lips

  • O-ring solutions


Typical applications
Wiper seals are used in hydraulic and pneumatic cylinders.


Technical support
Selecting the right wiper seal has a direct impact on service life and operational reliability. An incorrect choice can lead to premature wear and leakage in the sealing system.

FAQ
What does a wiper seal protect against?
Dirt and particles that would otherwise cause wear in the cylinder.

When should you choose a double-lip design?
When increased protection is required and reduced oil film on the piston rod is desired.

Which material should you choose?
TPU and NBR are standard choices. PTFE is used for high-speed applications (up to 5 m/s), while FPM is suitable for high-temperature conditions.
