About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X270-10S
The AirTAC SAIJ100X270-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers substantial thrust, providing 7068N of push force at 0.9 MPa and 3681N of pull force at 0.5 MPa. The integrated -S magnet enables position feedback via CMSE reed and DMSE electronic sensors mounted in the dual-side extruded barrel grooves.
This specific SKU features a 270 mm nominal stroke with a 10 mm rear adjustment screw, creating a 260-270 mm usable travel window. This allows precise end-position tuning during commissioning without adding external stops. The carbon steel piston rod features an M20x1.5 thread, and the cylinder uses PT tapered port threads with a G1/2 port size.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X270-10S Is Used
Heavy Assembly Pressing
Dial in the exact 260-270mm end-stop for pressing bearings, ensuring consistent seating force without over-travel.
Product Diversion Tuning
Fine-tune the actuator endpoint during line changeovers to accommodate varying package sizes on the fly.
Machine Commissioning
Adjust the rear stopper during setup to perfect the resting position of heavy tooling without external shims.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X270-10S the Right Cylinder?
Choose this 100 mm bore cylinder when an application requires heavy thrust but demands exact end-stop tuning. If you need less force, stepping down to an 80 mm bore yields 4523N push force at 0.9 MPa. The 10 mm rear adjuster acts solely as a travel stop to fine-tune the 260-270 mm window; it does not lock the load. For position holding without live air, select a SAIL (air-released lock) or BSAI (clamp-lock) cylinder. SAIJ uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. To replace an ISO 15552 cylinder, match the 100 mm bore, 270 mm stroke, 10 mm adjust, G1/2 PT 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 SAIJ100 Adjustable Cylinder SAIJ100X270-10S FAQ
It provides 7068N of push force at 0.9 MPa and 3681N of pull force at 0.5 MPa. The maximum operating pressure is 1.0 MPa.
The rear adjuster screw lets you shorten the 270mm nominal stroke by up to 10mm, creating a 260-270mm travel window. It functions as a hard stop for end-position tuning, not a load-holding lock.
