Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX1000-20S
The AirTAC Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX1000-20S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø63mm bore and 1000mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX1000-20S
The AirTAC SAIJ63X1000-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the effective travel within a 980 to 1000 mm window during commissioning. It features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and uses PT tapered port threads. The integrated magnet (-S) supports AirTAC CMSE reed and DMSE electronic sensors, fitting cleanly into the dual-side barrel grooves.
Delivering 1559 N of push force and 1402 N of pull force at 0.5 MPa, this 63 mm bore unit operates at speeds between 30 and 800 mm/s. It includes adjustable air cushions at both ends to decelerate the load smoothly. The rear adjuster acts purely as a travel stop for end-position tuning and does not hold the load without live air pressure; for true load-holding, consider the SAIL or BSAI series.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX1000-20S Is Used
Machine Changeover
Dial in the exact 980-1000 mm end stop during product size transitions without physically replacing the cylinder or adding external mechanical stops.
Assembly Calibration
Fine-tune the final stroke position during machine commissioning to perfectly seat components, absorbing mechanical tolerance stack-ups.
Long-Stroke Positioning
Pushes parts along a lengthy conveyor lane, using the rear adjuster to set the precise release point for varying pallet sizes.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX1000-20S the Right Cylinder?
Choose this adjustable-stroke model when a standard 1000 mm SAI cylinder requires precise end-position calibration without adding external stops or swapping components. If your application needs less force, stepping down to a 50 mm bore yields 982 N of push force at 0.5 MPa, while stepping up to an 80 mm bore provides 2513 N. This SAIJ variant utilizes a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. Because the stroke is 1000 mm, an external guide is highly recommended to prevent excessive side-loading on the rod. To replace an ISO 15552 cylinder, match the 63 mm bore, 1000 mm stroke, 20 mm adjustment, PT G3/8 port, and -S magnet.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 SAIJ63AX1000-20S FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from the nominal 1000 mm down to 980 mm. It only sets the end position and does not lock the load without continuous air pressure.
