Applications
Seal Materials: High-strength HPU, High grade Rubber (V-packings), Enhanced PTFE, High-load Phenolic Guide Bands, Wear-resistant POM.
Pressure Range: ≤ 400 bar
Operating Speed: ≤ 0.5 m/s (Long-stroke Stability)
Temperature Range: -40°C min – 110°C max
Telescopic cylinders demand exceptional seal compactness and reliability due to their nested stage design. Our comprehensive sealing solutions cover every stage from the main barrel to the final plunger, ensuring precise alignment during long-stroke operations. Engineered to handle high side loads and harsh external contaminants during tipping and lifting cycles.
Technical Advantages
Heavy-Duty Guidance: High-load guide bands prevent metal-to-metal contact between stages, absorbing vibration and supporting intense lateral forces common in long-stroke applications.
Extreme Environment Protection: High-efficiency scrapers/wipers prevent dust, mud, and particles from entering the system, protecting seals and cylinder surfaces from premature wear.
Compact Geometry Optimization: Specially designed profiles fit perfectly into limited radial spaces, ensuring zero-leakage transitions across every stage during extension and retraction.
Anti-Extrusion Stability: Utilizing high-modulus materials that maintain lip integrity even under sudden back-pressure spikes during heavy lifting operations.
