Shaft seals are asymmetrical seals designed specifically for piston rods, featuring a complementary lip on the inside. They are suitable for one-way sealing in reciprocating hydraulic applications and offer excellent sealing performance. The groove conforms to ISO 5597. They can be used independently or as a secondary seal within a sealing system.
Features:
1. Excellent static and dynamic sealing performance;
2. Low friction, smooth movement, and strong residual oil recovery capability under dynamic conditions;
3. Simple structure, easy installation and maintenance.
