Precision-adjustable pneumatic cylinder featuring tool-free stroke adjustment via rotating end caps. The hardened stainless steel guide rings ensure 0.05mm maximum radial play during operation. Integrated shock absorbers reduce end-impact noise by 15dB compared to standard models. Compatible with ATEX Zone 2 environments when ordered with anti-static seals (SAIJ40X50-40/EX variant).
- CNC machine tool clamping/unclamping mechanisms
- Pharmaceutical blister packaging positioners
- Glass tempering oven door actuators
- Automotive test rigs requiring precise stroke calibration
- Food-grade conveyor diverter arms (FDA-compliant seals available)
Adjustment Protocol:
Loosen both locknuts (17mm wrench size), rotate end cap clockwise to reduce stroke
(max 5 full rotations), retighten nuts to 4.5±0.5 N·m torque. Lubricate adjustment
threads monthly with ISO VG32 pneumatic oil.
Avoid side-load exceeding 35N. For vertical
installations, use model with magnetic piston (SAIJ40X50-40/M) for position feedback.
Maximum cycle rate: 120 CPM @ full stroke.
