High-rigidity double-acting cylinder featuring chrome-plated piston rod (HRC45-50 hardness) and integrated magnet for position sensing. The precision honed tube ensures ≤0.05mm inner diameter tolerance, with 0.5μm Ra surface finish for optimal sealing. Designed for 5,000km service life under S1 mode (50mm/s speed). Requires ISO VG32 or equivalent turbine oil lubrication (1-2 drops per 1 million cycles).
- Automated assembly line clamping mechanisms
- Carton box folding machine actuators
- Plastic injection molding ejectors
- Automotive welding fixture positioning
- CNC machine tool chip conveyors
Maintenance tip:
Lubricate rod every 3 months using silicone-free grease (Molykote 111 recommended).
Avoid lateral loading exceeding 30N·m. For vertical mounting, use locknut (ASNU6) to prevent self-rotation.
