Precision stroke-adjustable pneumatic cylinder featuring dual-position mechanical locking for stable stroke setting. The SAIJ63AX85-20 combines high rigidity with fine adjustment capability (0.5mm graduation marks), using a hexagonal locking mechanism to prevent accidental stroke changes. Compatible with both air and hydraulic fluids (NBR seals required for oil).
- Variable height positioning in packaging line stoppers
- Pressure-sensitive clamping devices
- Tooling fixture adjustments in CNC machining centers
- Material handling systems requiring periodic stroke changes
- Automated paint sprayer height control
Installation tip:
Apply thread locker (medium strength) on adjustment bolts after final stroke setting.
Maintain 15° maximum angular misalignment during side load operations.
Lubricate with ISO VG32 hydraulic oil for optimal seal performance.
