Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X800-100S
The AirTAC Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X800-100S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø63mm bore and 800mm 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 SAIJ63X800-100S
The AirTAC SAIJ63X800-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 63mm bore and an 800mm nominal stroke that can be dialed back by up to 100mm, providing a usable travel window of 700-800mm for precise end-position tuning during commissioning. This standard carbon steel rod variant generates 1559N of pull force at 0.5MPa and includes a magnet for position sensing.
It uses PT tapered port threads (G3/8) and achieves speeds of 30-800mm/s. The extruded aluminum barrel includes sensor grooves on both sides, accepting AirTAC CMSE reed and DMSE electronic switches. The rear adjuster acts purely as a mechanical stop to decelerate and set the travel end; it does not hold the load without live air pressure. For load-holding requirements without live pressure, consider the SAIL or BSAI series.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X800-100S Is Used
Machine Setup & Changeover
Dial in the exact 700-800mm travel window during line changeovers to accommodate different product lengths without replacing the entire actuator.
Commissioning Fine-Tuning
Use the rear mechanical stopper to precisely trim the end-of-stroke position during initial setup, absorbing minor mechanical tolerances without external shims.
Variable End Stops
Adjust the retract distance on the fly for conveyor sorting mechanisms that handle varying package sizes, ensuring accurate positioning every time.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X800-100S the Right Cylinder?
Choose this 63mm bore adjustable-stroke cylinder when an application requires variable end-stops or frequent product-size changeovers without physically swapping the cylinder or adding external stops. If your process demands less force, stepping down to a 50mm bore yields 825N of pull at 0.5MPa, whereas stepping up to an 80mm bore provides 2268N.
Because the 800mm stroke is quite long, the 20mm diameter carbon steel rod and M16x1.5 thread will experience amplified side loads; an external guide is strongly recommended to prevent premature seal wear. This SAIJ model supports a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. It is dimensionally interchangeable per ISO 15552.

- ✓ 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 SAIJ63X800-100S FAQ
At 0.5MPa operating pressure, this 63mm bore cylinder provides 1559N of pull force and 1402N of push force. It can reach a maximum of 318 kgf at 1.0MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from the 800mm nominal stroke down to 700mm. This creates a 700-800mm usable window, but it only sets the travel end and does not lock the load without live air pressure.
