About the Airtac SAIJ125 Adjustable Cylinder SAIJ125X160-100S
The AirTAC SAIJ125X160-100-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 60 to 160 mm, allowing you to dial back the nominal 160 mm stroke by up to 100 mm during commissioning without swapping the unit. In the 125 mm bore class, it generates 6136 N push and 5734 N pull force at 0.5 MPa, scaling up to 11045 N push at 0.9 MPa.
This -S variant includes a magnet for CMSE reed and DMSE electronic sensors, fitting directly into the dual-side sensor grooves on the extruded aluminum barrel. The PT tapered port is G1/2, and the 32 mm carbon steel rod with an M27x2 thread handles high side loads, though long unsupported travel still requires an external guide. The rear adjuster acts strictly as a travel stop, so live air is required to maintain position.

Where the Airtac SAIJ125 Adjustable Cylinder SAIJ125X160-100S Is Used
Variable End-Stop Forming
Dial in the exact retraction point for multi-stage forming operations, adjusting the 60-160 mm travel window on the fly to accommodate different material thicknesses.
Product Line Changeover
Rapidly reconfigure end positions during product size changes without physically replacing the cylinder or bolting on external mechanical stops.
Assembly Machine Setup
Fine-tune the rear stroke adjuster during initial commissioning to perfectly time the 11045 N push force against mating assembly tooling.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125X160-100S the Right Cylinder?
Choose this 125 mm bore when 80 mm (2513 N push at 0.5 MPa) is insufficient or 160 mm (10053 N at 0.5 MPa) is excessive for your machine. An adjustable stroke is preferred over a fixed SAI when you need variable end-stops for product changeovers. The rear screw fine-tunes the retraction point without adding external stops.
For an exact ISO 15552 replacement, match the 125 mm bore, 160 mm stroke, 100 mm adjustment, PT G1/2 port, and -S magnet. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR. Because the adjuster is a stop and not a lock, use an external rod lock or SAIL cylinder if the load must be held without live air pressure.
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 SAIJ125 Adjustable Cylinder SAIJ125X160-100S FAQ
At 0.5 MPa operating pressure, this 125 mm bore cylinder provides 6136 N of push force and 5734 N of pull force. At 0.9 MPa, the push force increases to 11045 N.
The rear adjuster screw lets you trim the effective travel back from the 160 mm nominal stroke by up to 100 mm, creating a 60 to 160 mm usable window. The adjuster acts as a mechanical stop and does not lock the load without live air.
