About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X95-40S
The AirTAC SAIJ63X95-40-S is a double-acting ISO 15552 profile cylinder featuring a rear mechanical stopper that allows you to fine-tune the travel end. With a nominal 95mm stroke and a 40mm adjustment range, you get a usable travel window of 55-95mm to perfectly dial in end positions during commissioning. This bore delivers 1559N of push force at 0.5MPa, supported by a 20mm carbon steel rod and M16x1.5 thread that handles high side loads well.
Equipped with a magnet for position sensing, this unit works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches housed in the dual sensor grooves. It uses PT tapered port threads (G3/8) and supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X95-40S Is Used
Machine Setup Calibration
Dial in the exact 55-95mm travel window during initial commissioning to perfectly align stamping or pressing dies without external shims.
Product Size Changeover
Quickly adjust the retract stop on packaging lines when switching between different carton or package sizes.
Variable End-Stop Positioning
Fine-tune the end-of-stroke position on demand for delicate assembly tasks requiring precise mechanical limits.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X95-40S the Right Cylinder?
Choose this 63mm bore over the smaller 50mm (982N push at 0.5MPa) when your application demands higher thrust, or step up to the 80mm (2513N) for heavy material handling. An adjustable stroke is preferred over a fixed SAI cylinder when you need variable end-stops for quick product changeovers without physically swapping the actuator.
Remember that the rear adjuster and the variable air cushions only decelerate the load; they do not hold position without live air. For fail-safe load holding, consider the SAIL or BSAI series. To replace an ISO 15552 cylinder, match the 63mm bore, 95mm stroke, 40mm adjustment, PT G3/8 port, required mounting, and the -S magnet.

Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X95-40S FAQ
The SAIJ63X95-40-S uses a rear adjusting screw to mechanically shorten the retract stroke. With a 95mm nominal stroke and a 40mm adjustment range, you can set the effective travel anywhere within a 55-95mm window.
At 0.5MPa operating pressure, this double-acting cylinder provides 1559N of push force and 1402N of pull force. At the maximum 1.0MPa pressure, it delivers up to 318 kgf.
