Heavy-wall cylinder specifically engineered for construction equipment applications. Features triple sealing system (rod seal, buffer seal, and wiper) with anti-vibration design. The piston rod incorporates a chrome-plated surface with multi-layer polishing (Ra ≤0.2μm) for enhanced wear resistance in abrasive environments. Includes built-in cushion adjustment screws with locknuts for precise deceleration control.
- Excavator bucket control mechanisms
- Concrete pump truck boom positioning
- Pile driver impact systems
- Crane outrigger stabilization
- Rock crusher feed gate operation
Installation notes:
Requires minimum 40μm filtration. For vertical installations exceeding 45° angle,
use rod-end support brackets (B04-SUPT kit recommended). Lubricate with ISO VG32
grade oil for first 500km of operation. Avoid side load forces exceeding 150N.
- Re-lubricate every 2,000 operating hours
- Replace wiper seals after 10,000km stroke distance
- Inspect buffer seals annually under continuous vibration conditions
