About the Airtac SAIJ125 Adjustable Cylinder SAIJ125X110-100
The AirTAC SAIJ125X110-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers 6136N of push force at 0.5 MPa, making it suited for heavy-duty positioning. The rear stopper screw provides a usable travel window from 10 to 110 mm, allowing you to dial back the nominal stroke by up to 100 mm during machine commissioning.
This extruded aluminum barrel utilizes PT tapered port threads (G1/2) and includes dual-side sensor grooves. You can mount CMSE reed or DMSE solid-state switches if position feedback is later required. The integrated variable air cushions at both ends decelerate the load, but the adjuster acts strictly as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ125 Adjustable Cylinder SAIJ125X110-100 Is Used
Variable End-Stop Positioning
Dial the rear screw to set precise end-stops between 10 and 110 mm for heavy press operations that require frequent adjustments without changing the cylinder.
Machine Setup & Commissioning
Fine-tune the travel limit during initial machine commissioning to compensate for mechanical tolerances, using the 100mm adjustment range to find the perfect contact point.
Product-Size Changeovers
Quickly adapt a packaging line for different product sizes by retracting the stroke stopper, leveraging the 6136N of force to move heavy pallets or fixtures.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125X110-100 the Right Cylinder?
Choose this 125mm bore when an application requires substantial thrust—such as 6136N push at 0.5 MPa—surpassing the 3927N available from the 100mm bore, but without stepping up to the 160mm class. An adjustable stroke is highly beneficial here for product changeovers, allowing the end-stop to be fine-tuned between 10 and 110 mm without swapping hardware. For fixed travel needs, a standard SAI cylinder is simpler.
This model uses PT tapered ports and the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets. Although the stroke is under 300mm, the 32mm rod and M27x2 thread handle high side loads, but an external guide is still recommended for heavy offset loads. Since the rear adjuster is not a lock, use an SAIL or BSAI cylinder if the load must be held without continuous 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 SAIJ125X110-100 FAQ
At an operating pressure of 0.5 MPa, this 125mm bore cylinder provides a push force of 6136N and a pull force of 5734N. At the maximum pressure of 1.0 MPa, it can deliver up to 1251 kgf.
The SAIJ125X110-100 has a nominal 110mm stroke with a 100mm adjustment range, allowing the effective travel to be shortened to anywhere between 10 and 110 mm. The rear screw acts as a mechanical stop to tune the end position, but it does not lock the load without live air pressure.
