UNS UHS piston rod seal

 

UNS/UHS is a lip seal which can be used for both piston and rod.

 

This kind of seal has a smaller loading surface and can be installed in the integral groove. The high wear-resistant PU polyurethane material with 90 shore hardness can ensure a wide working temperature range.

 

There should be clearance between shafts when installing such seals. In order to avoid damage to the sealing lip, measures should be taken to avoid sharp edges during installation.

Advantages:

1. High sealing performance under low pressure.
2. Not suitable for sealing singly.
3. hydraulic piston rod seal is easy installation.
