Precision stroke-adjustable cylinder featuring dual-position mechanical stops for mid-stroke positioning. The SAIJ series incorporates a unique anti-rotation rod design with hexagonal piston rod cross-section, preventing spindle rotation during adjustment. Optimized for applications requiring variable stroke lengths without cylinder replacement.
- Variable depth pressing in PCB assembly fixtures
- Adjustable clamping mechanisms for CNC tooling
- Material handling systems with product size variation
- Semiconductor wafer processing equipment
- Packaging line format change adaptations
Installation protocol:
Apply thread locker (medium strength) to adjustment screws after final positioning.
Requires monthly lubrication (ISO VG32 equivalent pneumatic oil) through built-in nipples.
Avoid side load exceeding 30N during operation.
Note: When used in vertical downward orientation, recommend adding 10-15% extra pressure compensation for gravity effects. Not suitable for high-speed applications (>500mm/s).
