About the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX1000-100S
The AirTAC SAIJ125X1000-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 900-1000 mm usable travel window. Equipped with a SUS420J2 stainless steel rod and a -S magnet, it delivers 6136 N pull force at 0.5 MPa. The PT tapered ports and extruded aluminum barrel ensure robust performance.
This model allows precise end-position tuning at commissioning without swapping the cylinder or adding external stops. The rear adjuster acts strictly as a travel stop for deceleration, not a lock, so live air is required to hold the load. It supports AirTAC CMSE reed and DMSE electronic sensors in the dual side sensor grooves.

Where the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX1000-100S Is Used
Product Size Changeover
Quickly fine-tune the 900-1000 mm end-stop during format changeovers on packaging lines without mechanical rebuilds.
Long-Stroke Diverting
Handles heavy conveyor routing tasks where a 1000 mm travel is occasionally shortened to 900 mm for varying pallet sizes.
Heavy Press Positioning
Provides 6136 N pull at 0.5 MPa for large press feeding, using the rear stop to dial in the exact insertion depth.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX1000-100S the Right Cylinder?
Choose this 125 mm bore when a smaller 100 mm bore (providing 3681 N pull at 0.5 MPa) lacks the thrust for heavy positioning, but before stepping up to a 160 mm bore (9425 N pull). The adjustable stroke is ideal for product-size changeovers on a line, letting you dial back the nominal 1000 mm stroke by up to 100 mm. For fixed stops, a standard SAI cylinder is simpler.
Because this stroke is 1000 mm, the 32 mm rod and M27x2 thread still require an external guide to prevent excessive side loading on the piston. This SAIJ variant uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR. It is dimensionally interchangeable per ISO 15552. If you need true load-holding without air pressure, use a SAIL or BSAI cylinder instead.
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 SAIJ125AX1000-100S FAQ
At 0.5 MPa it provides 6136 N push and 5734 N pull. At 0.7 MPa the push increases to 8590 N, and it reaches a maximum of 11045 N push at 0.9 MPa.
The rear adjuster screw lets you trim the effective travel back by up to 100 mm from the 1000 mm nominal stroke, creating a 900-1000 mm usable window. It functions as a hard stop for deceleration, not a lock, so it cannot hold the load without live air pressure.
