About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-75
The AirTAC SAIJ160X950-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 950 mm nominal stroke that can be dialed back by up to 75 mm, creating an 875-950 mm usable travel window for precise end-position tuning during commissioning. Belonging to the 160 mm bore class, it delivers up to 14074 N of push force at 0.7 MPa, making it suitable for heavy-duty positioning tasks.
This model features a SUS304 stainless steel piston rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is built without a magnet for position sensing. The rear adjustment screw acts purely as a mechanical stop to set the travel end and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-75 Is Used
Variable End-Stop Positioning
Dial in the 875-950 mm travel window during machine commissioning to set exact retract distances for heavy-duty tooling without adding external stops.
Product-Size Changeover
Quickly adapt the cylinder's effective stroke on the production line when handling different large-format product sizes, minimizing downtime.
Heavy-Duty Machine Setup
Leverage the 14074 N push force and 40 mm stainless rod for heavy industrial positioning tasks requiring fine-tuned travel limits.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-75 the Right Cylinder?
Choose this 160 mm bore cylinder when an application demands high thrust (14074 N at 0.7 MPa) alongside variable end-stop positioning. If you need less force, stepping down to a 125 mm bore provides 8590 N, while moving up to a 200 mm bore yields 21991 N. The adjustable stroke is selected over a fixed SAI cylinder when machine setups require frequent product-size changeovers without swapping physical cylinders.
Because the 950 mm stroke is long, the 40 mm diameter SUS304 rod and M36x2 thread still require an external guide to prevent excessive side-loading and rod bending. For any load-holding requirements without continuous air pressure, note that the rear adjuster is only a stop; you must use a SAIL (air-released lock) or BSAI (clamp-lock) cylinder instead. This SAIJ model is dimensionally interchangeable per ISO 15552 and uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ160BX950-75 FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates a push force of 14074 N and a pull force of 9425 N. It can deliver a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster acts as a mechanical stop that allows you to shorten the 950 mm nominal stroke by up to 75 mm, providing an adjustable travel window of 875 to 950 mm. It only sets the end position and does not lock or hold the load without live air pressure.
