High-Pressure Seal Kit for Drill-Boom Telescopic Cylinders
Engineered for extreme mining environments, this seal kit ensures reliable sealing in drill-boom 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 35 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 35 MPa dynamic pressure and 42 MPa static pressure, exceeding industry standards for drill-boom cylinders .
  • Wide Temperature Range: Operates reliably from -30°C to +90°C, suitable for extreme mining environments .
  • Longevity: Passed 8,000-cycle durability testing under 35 MPa dynamic pressure, ensuring minimal maintenance .

 

Applications
  • Drill-Boom Telescopic Cylinders: Restores sealing efficiency in Sandvik DL421/HLX6 and compatible models.
  • Mining Machinery: Used in drill rigs, excavators, and material handling equipment requiring high-pressure sealing.
  • Industrial Hydraulics: Supports presses, cranes, and conveyor systems in high-vibration environments.
