A heavy-duty industrial cylinder engineered for long-stroke applications requiring precise linear motion. Features triple sealing system (rod seal, piston seal, and wiper) with wear-resistant guide bands for smooth operation. The extended stroke design incorporates anti-rotation guidance to maintain alignment integrity during full extension.
- Automated material handling systems (conveyor gate actuators)
- Press machine ejection mechanisms
- Automotive assembly line positioning arms
- Packaging equipment compression units
- Foundry mold clamping operations
Installation guidance:
For optimal performance in vertical mounting positions, use external guide mechanisms when handling
side loads exceeding 30N. Lubricate with ISO VG32 hydraulic oil if operating below 0.15 MPa.
Critical note:
Stroke tolerance is ±1.5mm – account for thermal expansion when used in environments with
temperature fluctuations exceeding ±15℃ during operation.
