HRDA
High-Quality Dust Seal
Advantages and Characteristics
HRDA is made of PPDI. It is of high elasticity with excellent performance. Resistant to high pressure impact. Effectively avoiding hydraulic oil leakage. Longer service life of 6 years (10,000 hours).
The added lip is located on the surface of the groove that is not rusted, perfectly preventing oil leakage from the outer side of the rod seal in the event of damage to the outer side.
This added auxiliary lip can improve the eccentric load during the reciprocating movement of the piston rod, and it plays a certain supporting role.
