High-torque industrial cylinder featuring precision honed tubing and triple sealing system (rod seal, piston seal, and buffer seal). Designed for heavy-duty cycles with 50km+ service life under standard conditions. Requires 5-40μm filtered air and ISO VG32 hydraulic oil lubrication (optional oil mist lubrication).
- Automotive assembly line clamping mechanisms
- Press machine ejection systems
- Packaging line pusher actuators
- Foundry equipment door operators
- Plastic injection molding machine core pullers
Installation tip:
Allow 5mm minimum clearance around cylinder body for heat dissipation.
Lubricate through air supply (oil mist) or manual greasing every 3,000km stroke.
For vertical mounting, install rod-down position to prevent condensate accumulation.
