About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX165-40
The AirTAC SAIJ100X165-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 165 mm travel by up to 40 mm for a usable window of 125-165 mm. It delivers substantial thrust, pushing 5497 N and pulling 3681 N at 0.7 MPa, making it well-suited for heavy actuation tasks. The extruded aluminum barrel features sensor grooves on both sides for flexible switch placement.
This unit is built with an SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and features PT tapered port threads with a G1/2 connection. The rear adjuster acts purely as a mechanical stop to fine-tune the retract position during commissioning; it does not lock the load without continuous air pressure. For position holding, an external SAIL or BSAI locking cylinder is required.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX165-40 Is Used
Product Changeover
Quickly shift the retract end-stop within the 125-165 mm window to accommodate different product lengths on the same line without changing the cylinder.
Heavy Pressing
Leverage the 5497 N push force at 0.7 MPa to securely seat or press heavy components, fine-tuning the final position at the machine.
Machine Commissioning
Dial in the exact end position during setup using the rear screw, avoiding the need to machine custom external spacers or stop blocks.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX165-40 the Right Cylinder?
Choose this 100 mm bore when a 63 mm cylinder (providing 2182 N push at 0.5 MPa) is insufficient, but a 125 mm bore is excessive. The 40 mm adjustment range is ideal for product changeovers, letting you shift the end-stop precisely without swapping cylinders or adding external stops. If your machine requires the load to stay held when air pressure drops, remember that this standard SAIJ adjuster is not a brake—you must integrate a SAIL air-released lock or a BSAI clamp-lock cylinder.
To match this ISO 15552 interchangeable cylinder exactly, specify: 100 mm bore, 165 mm stroke, 40 mm adjustment, PT G1/2 port, and no magnet (-S omitted). Mounting options are limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).
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 SAIJ100AX165-40 FAQ
At 0.7 MPa operating pressure, this 100 mm bore cylinder provides a push force of 5497 N and a pull force of 3681 N. At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw lets you mechanically shorten the 165 mm nominal stroke by up to 40 mm, creating a usable travel window of 125-165 mm. It functions as a hard stop for end-position tuning and is not a lock.
