About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX950-100
The AirTAC SAIJ160X950-100 is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty applications. It integrates a rear adjusting screw that allows you to trim the effective stroke, providing a usable travel window of 850 to 950 mm. Delivering massive thrust, it generates 14074 N of push force at 0.7 MPa and up to 18095 N at 0.9 MPa.
This variant features a robust 40 mm piston rod with an M36x2 thread, machined from SUS420J2 stainless steel for superior corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides, and the pneumatic design incorporates variable air cushions at both ends to decelerate heavy loads smoothly.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX950-100 Is Used
Heavy Machinery Positioning
Fine-tune the 850-950 mm end position during commissioning of large presses or heavy material handlers without altering the fixed machine framework.
Product Size Changeover
Dial in the stroke up to 100 mm to accommodate different product lengths on an automated assembly line, minimizing downtime between production runs.
Long-Stroke Assembly Presses
Utilize the 950 mm travel for deep reach operations while relying on the adjustable stop to set precise pressing depths for various components.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX950-100 the Right Cylinder?
Selecting this 160 mm bore cylinder is appropriate when your application requires substantial force, such as 10053 N push at 0.5 MPa, which exceeds the 6136 N capacity of the neighboring 125 mm bore. The 100 mm adjustment range is ideal for production lines needing variable end-stops during product changeovers, eliminating the need to physically swap cylinders or bolt on external stops. Because the stroke is 950 mm, an external guide should be used to support the load and prevent excessive side-loading on the rod.
When specifying a replacement, ensure you match the 160 mm bore, 950 mm nominal stroke, 100 mm adjustment code, PT G3/4 port thread, and the SUS420J2 rod material. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for positive load-holding, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ160 Adjustable Cylinder SAIJ160AX950-100 FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder provides a push force of 14074 N and a pull force of 9425 N. At 0.9 MPa, the push force increases to 18095 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 950 mm nominal stroke by up to 100 mm, creating an effective travel window of 850 to 950 mm. This stopper only sets the end position and does not lock the load without continuous air pressure.
