High-Pressure Seal Kit for Advance-Beam Telescopic Cylinders Engineered for extreme mining environments, this seal kit ensures reliable sealing in advance-beam telescopic cylinders 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 30 MPa dynamic pressure .
PTFE-Coated Guide Rings: Reduces friction and wear during linear motion, ensuring smooth operation of telescopic cylinders.
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 30 MPa dynamic pressure and 42 MPa static pressure, exceeding industry standards for advance-beam cylinders .
Wide Temperature Range: Operates reliably from -40°C to +80°C, suitable for extreme mining environments .
