About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X800-10
The AirTAC SAIJ63X800-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 800mm nominal travel by up to 10mm. This creates a 790-800mm usable window for fine-tuning the retract end position during commissioning without adding external stops. It delivers 1559N of pull force at 0.5MPa and 2182N at 0.7MPa.
The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed and DMSE electronic switches if position feedback is later required. Featuring a G3/8 port and a 20mm carbon steel rod with an M16x1.5 thread, this model omits the FB, CA, CB, and CR mounts, utilizing a reduced SAIJ mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X800-10 Is Used
Product Changeover Lines
Quickly shift the retract end-stop by up to 10mm to accommodate slightly different package lengths on a packaging conveyor without swapping cylinders.
Machine Setup Tuning
Dial in the exact 790-800mm end-of-stroke position during initial commissioning to perfectly align a tooling fixture, avoiding the need for machined spacer plates.
Adjustable Material Pushers
Push materials to a varying backstop location on an assembly line, using the rear adjuster to set the precise final resting position for each batch run.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X800-10 the Right Cylinder?
Choose this 63mm bore when a 50mm bore (982N pull at 0.5MPa) is too weak, but an 80mm bore (2268N pull at 0.5MPa) would be physically oversized. The 10mm adjustment range is ideal for variable end-stops or product-size changeovers on a line, providing setup flexibility that a fixed-stroke SAI cannot match.
Because the 800mm stroke is quite long, the 20mm rod and M16x1.5 thread will still need an external guide to prevent excessive side-loading and sagging. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider the SAIL or BSAI series. This unit is dimensionally interchangeable per ISO 15552 mounting-interface dimensions.
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 SAIJ63X800-10 FAQ
At 0.5MPa, this 63mm bore cylinder provides 1559N of pull force and 1402N of push force. If you increase the operating pressure to 0.7MPa, the push force rises to 2182N.
The rear external screw acts as a mechanical stopper, allowing you to shorten the effective travel from 800mm down to 790mm. It only sets the travel end and does not lock or hold the load without live air pressure.
