High-precision industrial cylinder featuring corrosion-resistant construction and dual anti-rotation guide rods. The T-slot design allows flexible accessory mounting. Optimized for heavy-load applications with 20% increased thrust compared to standard ISO cylinders. Requires ISO VG32 hydraulic oil mist lubrication (0.3–0.6cc/min recommended).
- Automated production line material handling
- Die-casting machine ejection systems
- Paper processing equipment actuators
- Automotive welding fixture positioning
- Packaging machine vertical lift mechanisms
Installation guidelines:
Maintain 0.5mm minimum clearance between rod end and load. Use flexible couplings
for angular misalignment exceeding ±2°. For vertical mounting, install speed
controller on lower port. Replace wiper seal every 5 million cycles in dusty environments.
