High-precision industrial cylinder featuring stepless stroke adjustment through external mechanical stoppers. The integrated shock absorption system minimizes end-impact noise while maintaining positioning accuracy (±0.5mm repeatability). Corrosion-resistant construction with IP54 protection rating ensures reliable operation in harsh environments.
- Variable-height positioning in automated assembly lines
- Press-fit operations with controlled insertion depth
- Material handling systems requiring adjustable lift heights
- Packaging machinery for product height compensation
- Die-casting machine ejection mechanisms
Installation note:
Requires periodic lubrication (ISO VG32 hydraulic oil recommended).
Maintain 0.5mm minimum clearance between stopper and rod end during adjustment.
For vertical mounting, use reinforced mounting brackets (accessory code: BR-80V).
- Loosen both lock nuts on the adjustable stopper
- Position stopper to desired stroke position using scale markings
- Re-tighten lock nuts to 25-30 N·m torque
- Perform test cycle at reduced pressure before full operation
