About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X475-10
The AirTAC SAIJ100X475-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 475 mm travel distance with a 10 mm adjustment range, yielding a usable 465-475 mm end-position window for precise commissioning. Operating at 0.5 MPa, it delivers 3927 N of push force and 3681 N of pull force, making it suitable for heavy-duty positioning tasks.
This extruded aluminum profile cylinder includes a 25 mm carbon steel rod with an M20x1.5 thread, designed to handle significant side loads while maintaining stable guidance. It features variable air cushions at both ends (36 mm cushion length) to absorb impact energy. The rear adjuster acts strictly as a travel stop for end-position tuning and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X475-10 Is Used
Machine Changeover
Dial in the 10 mm stroke adjustment window during product size transitions to set new end positions without physically replacing the actuator.
Heavy Duty Positioning
Leverage the 3927 N push force to move heavy pallets or fixtures into their final confirmed stop position on the assembly line.
Commissioning Fine-Tune
Use the rear stopper screw to trim the travel window down to 465 mm during initial setup to clear mechanical interference without adding external stops.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X475-10 the Right Cylinder?
Choose this 100 mm bore model when an application requires substantial thrust, such as the 3927 N push force at 0.5 MPa, combined with exact end-position tuning. If your setup needs less force, stepping down to an 80 mm bore yields 2513 N, while a 125 mm bore increases output to 6136 N. The 10 mm rear adjustment screw allows you to dial in the exact 465-475 mm stroke during machine changeover without swapping the cylinder.
Because the 475 mm stroke is relatively long, ensure you use an external guide to support the rod and prevent excessive side-loading. For any load-holding requirements without continuous air pressure, note that this rear stopper is not a lock; you would need to specify a SAIL or BSAI cylinder instead. This SAIJ model is dimensionally interchangeable per ISO 15552 mounting interfaces and uses a G1/2 PT port.
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 SAIJ100 Adjustable Cylinder SAIJ100X475-10 FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides a push force of 3927 N and a pull force of 3681 N. At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster allows you to shorten the 475 mm nominal stroke by up to 10 mm, creating a usable travel window of 465-475 mm. The adjuster acts as a mechanical stop to fine-tune the end position and is not a locking device.
