Precision-adjustable pneumatic cylinder featuring a dual-rod design for enhanced stability during mid-stroke positioning. The external mechanical stopper allows ±0.5mm repeatability through hex key adjustment. Integrated wear bands prevent metal-to-metal contact, making it suitable for high-cycle applications (up to 1.5 million cycles at rated load). Includes built-in auto-escape mufflers and impact-resistant cushioning system.
- Variable-height workholding fixtures in CNC machining centers
- Adjustable clamping mechanisms for injection molding gates
- Position-staged material handling in conveyor systems
- Precision web tension control in printing machinery
- Height-adjustable packaging seal bars
Installation tip:
When using full stroke adjustment, reduce operating pressure by 15% to compensate for increased piston acceleration distance. For vertical mounting, install rod lock nuts (ANJ40-10 accessory recommended) to prevent unintended position drift.
- Re-lubrication every 3 months or 2,000 operating hours
- Use ISO VG32 turbine oil for maintenance
- Maximum side load: 135N at full extension
- Rod wiper replacement recommended every 500,000 cycles
