High-Pressure Seal Kit for Hydraulic Rock Drills Engineered for extreme mining environments, this seal kit ensures reliable sealing in hydraulic rock drills and heavy-duty equipment. The kit includes polyurethane YX-D piston seals and PTFE-coated guide rings for high-pressure reciprocating motion, complemented by polyurethane dust seals to prevent debris ingress .
Technical Specifications & Design
Core Components:
YX-D Piston Seals: Polyurethane seals with YX-D profile (JB/ZQ4264-97 compliant) for bidirectional sealing in piston applications, capable of withstanding 35 MPa dynamic pressure .
PTFE-Coated Guide Rings: Reduces friction and wear during linear motion, ensuring smooth operation of hydraulic rock drills.
ISO 3601-1 O-rings: Precision-machined NBR O-rings for static and dynamic sealing, compliant with international standards .
Polyurethane Dust Seals: 45° chamfered design to exclude dust and rock fragments, extending service life in harsh conditions.
Performance Advantages
High-Pressure Resistance: Tested to 35 MPa dynamic pressure and 42 MPa static pressure, exceeding industry standards for hydraulic rock drills .
Wide Temperature Range: Operates reliably from -30°C to +90°C, suitable for extreme mining environments.
