Heavy-duty industrial cylinder with anti-rotation mechanism and precision-machined guide bands. Features an integrated shock absorption system with oil-filled adjustable cushions, reducing end-impact noise by 30% compared to standard models. The steel tube body provides 4x higher lateral load capacity than aluminum cylinders. Requires 40μm filtered lubricated air (ISO 8573-1 class 4).
- Automotive stamping press ejection systems
- Foundry equipment for mold clamping
- Paper roll handling in converting machinery
- Heavy payload robotic arm actuators
- Shipbuilding plate bending machines
Installation guidelines:
Maximum allowable misalignment: ±0.5° axial deviation.
For vertical mounting, use reinforced rod-end support brackets (ASNU-250 recommended).
Lubricator oil viscosity: ISO VG32 or equivalent, 1 drop/5 cycles minimum.
