About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X800-10
The AirTAC SAIJ100X800-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. With a nominal 800 mm stroke and a 10 mm adjustment range, it provides a usable travel window of 790 to 800 mm. This allows precise end-position tuning at commissioning without swapping the cylinder or adding external stops. It delivers 5497 N of push force at 0.7 MPa.
This model uses a 25 mm carbon steel rod with an M20x1.5 thread, providing robust resistance to side loads. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is specified later. It features a variable air cushion at both ends and operates at speeds of 30-800 mm/s.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X800-10 Is Used
Variable End-Stop Tuning
Dial in the exact retraction point within a 790-800 mm window during machine commissioning without physically replacing the actuator.
Product Size Changeover
Quickly adapt automated lines to different product lengths by turning the rear screw to shift the stroke end position by up to 10 mm.
High-Force Positioning
Leverage 5497 N of push force at 0.7 MPa to move heavy pallets or fixtures while fine-tuning the final resting position on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X800-10 the Right Cylinder?
Choose this 100 mm bore cylinder when an application requires substantial thrust—stepping down to an 80 mm bore yields 3518 N at 0.7 MPa, while moving up to 125 mm provides 8590 N. The adjustable stroke is ideal for product changeovers on a line, allowing you to dial in the exact end-stop within that 790-800 mm window. For load-holding without live air pressure, note that the rear adjuster acts only as a travel stop and deceleration device, not a lock; you would need an SAIL or BSAI cylinder for that function.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 800 mm stroke, 10 mm adjustment, PT tapered port thread, and the specific mounting set. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, but omits FB, CA, CB, and CR. Because the stroke is 800 mm, an external guide is recommended to prevent excessive rod deflection under load.

- ✓ 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 SAIJ100 Adjustable Cylinder SAIJ100X800-10 FAQ
It features a rear stopper screw that lets you shorten the effective travel by up to 10 mm, creating a 790-800 mm usable window. The adjuster acts as a mechanical stop for end-position tuning and does not hold the load without live air.
At 0.7 MPa, the SAIJ100X800-10 provides 5497 N of push force and 3681 N of pull force. At a maximum 1.0 MPa operating pressure, it can deliver up to 801 kgf.
