High-force industrial cylinder with precision honed tube and triple sealing system. Features chrome-plated piston rod with built-in magnet for sensor compatibility. Optimal for medium-stroke applications requiring smooth operation and position feedback. Requires ISO VG32 hydraulic oil mist lubrication for extended seal life.
- Press machine ejection systems
- Automated assembly line clamping
- Plastic injection molding machine gates
- Heavy-duty material handling equipment
- Packaging machine pusher mechanisms
Installation note:
Ensure proper alignment (max 0.2mm lateral deviation) and use flexible couplings
when connecting to moving parts. Perform 500-hour maintenance cycles including
rod surface cleaning and cushion needle adjustment.
Critical parameters:
Maximum side load capacity 280N at mid-stroke. Avoid rapid pressure changes
(>0.5 MPa/sec) to prevent seal extrusion. Use air dryer when relative humidity
exceeds 80%.
