About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX135-100S
The AirTAC SAIJ100X135-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 35 to 135 mm. Delivering 3927 N of push force at 0.5 MPa, it handles heavy-duty positioning with precision. The integrated -S magnet supports position sensing via AirTAC CMSE reed or DMSE electronic switches housed in the dual-side barrel grooves.
This unit features a SUS420J2 stainless steel rod (option A) for superior corrosion resistance and uses PT tapered port threads. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position without requiring cylinder swaps. It utilizes the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX135-100S Is Used
Product Changeovers
Dial in the exact 35 to 135 mm retract position during format size shifts on a packaging line without changing the physical cylinder mount.
End-Stop Calibration
Fine-tune the final end position during machine commissioning using the rear screw stopper to perfect part pressing or forming depths.
Heavy-Duty Positioning
Leverage the 3927 N push force at 0.5 MPa to move substantial jigs or tooling plates, using the adjustable window to set precise travel limits.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX135-100S the Right Cylinder?
Select this 100 mm bore cylinder when an application requires substantial thrust—up to 3927 N at 0.5 MPa or 7068 N at 0.9 MPa. If your project demands less force, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa, whereas a 125 mm bore provides 6136 N for heavier loads. The adjustable 35-135 mm travel window is ideal for machines requiring frequent product-size changeovers, eliminating the need to physically swap out a fixed-stroke SAI cylinder.
Because the nominal 135 mm stroke is relatively short, external side-load guides are less critical here, though the robust 25 mm rod and M20x1.5 thread handle standard kinetic stresses well. Remember that the rear adjuster and air cushions only decelerate the travel end; they do not hold the load without live air pressure. For fail-safe load holding, consider an AirTAC SAIL (pneumatic lock) or BSAI (clamp-lock) cylinder. This SAIJ model is dimensionally interchangeable with ISO 15552 cylinders.
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 SAIJ100AX135-100S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw allows you to trim the effective travel anywhere within a 35 to 135 mm window. It acts as a mechanical stop to set the end position, but it is not a lock and will not hold the load without continuous air pressure.
