Precision stopper cylinder featuring instant mechanical locking through pneumatic-hydraulic damping. The dual-shaft design ensures zero rotation during operation, with hardened guide rods for position retention accuracy within ±0.1mm. Integrated shock absorption reduces impact noise to ≤65dB(A). Requires 5μm filtered air with ISO VG32 hydraulic oil mist lubrication.
- PCB board positioning in SMT assembly lines
- Workpiece alignment in CNC rotary tables
- Pallet retention in automated warehousing systems
- Precision stopping in glass panel handling robots
- Tooling fixture locking in automotive part inspection
Installation note:
Maintain 0.5-1mm gap between stopper surface and workpiece. Lubricate guide rods weekly with ISO VG32 oil.
Avoid side-load exceeding 30N. For vertical mounting, use auxiliary support brackets.
