Precision-adjustable pneumatic cylinder featuring dual-side external cushioning screws for controlled deceleration. The JSIJ series combines 3-stage position adjustment (pre-stroke, mid-position lock, post-stroke) with visible stroke markings. Anti-rotation design maintains orientation stability during complex motions. Requires 5-40μm filtered lubricated air (ISO 8573-1 class 4).
- Precision press-fit operations in automotive assembly
- Variable height positioning in CNC tool changers
- Shock-sensitive packaging line stoppers
- Glass handling systems requiring soft landing
- Pharmaceutical tablet compression machines
Adjustment protocol:
Always depressurize before rotating cushion screws. Maximum 270° rotation per adjustment.
Use locknut (included) after fine-tuning. Lubricate weekly under high-cycle (>5,000/hr) use.
