About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX155-10
The AirTAC SAIJ100X155-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 145-155 mm usable travel window, allowing you to dial back the nominal 155 mm stroke by up to 10 mm during machine commissioning. Equipped with a 25 mm SUS420J2 stainless steel rod and a G1/2 PT port, it delivers 3927 N of push force at 0.5 MPa and 5497 N at 0.7 MPa.
This adjustable stopper lets you fine-tune end positions without swapping the cylinder or adding external stops. The rear adjuster acts purely as a travel stop and does not hold the load without live air; for true load-holding, consider SAIL or BSAI variants. It supports variable air cushions at both ends and uses a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX155-10 Is Used
Machine Setup Tuning
Dial in the exact 145-155 mm end position during initial commissioning without machining external stopper blocks.
Product Changeover
Quickly adjust the stroke by up to 10 mm on a packaging line when switching to a slightly different product size.
High-Force Clamping
Utilize the 5497 N push force at 0.7 MPa to secure heavy workpieces, with the adjuster acting as a mechanical stop.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX155-10 the Right Cylinder?
Select this 100 mm bore when an 80 mm bore (2513 N push at 0.5 MPa) is insufficient and you need higher thrust. The 10 mm adjustment window is ideal for precise end-position tuning at setup or product changeover, avoiding the need for a fixed-stroke SAI cylinder. Since the stroke is 155 mm, the 25 mm rod handles side loads well, but always guide the load externally for optimal bearing life.
For ISO 15552 replacement matching, specify bore 100, stroke 155, 10 mm adjustment, G1/2 PT port, and the SUS420J2 rod material (code A). No magnet is specified, so position sensing via CMSE or DMSE switches is not enabled out of the box.
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 SAIJ100AX155-10 FAQ
At 0.5 MPa it provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster allows you to shorten the effective travel from 155 mm down to 145 mm, giving a 10 mm tuning window. It functions as a travel stop only and does not lock the load without live air pressure.
