About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-20
The AirTAC SAIJ160X950-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 950 mm nominal travel to a precise 930-950 mm window during commissioning. Delivering 14074 N of push force at 0.7 MPa, this large-bore actuator handles heavy-duty positioning without requiring external stops. The extruded aluminum barrel integrates sensor grooves on both sides for straightforward switch mounting.
This variant features a SUS304 stainless steel rod (code B) for superior corrosion resistance in harsh environments. It uses a PT G3/4 port and achieves a standard operating speed of 30-500 mm/s. The rear screw acts purely as a travel stop to fine-tune the end position, meaning it cannot hold the load dynamically without continuous live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-20 Is Used
Heavy Fixture Positioning
Dial in the exact 930-950 mm end-stop during machine setup to position heavy welding fixtures without adding external mechanical stops.
Product Size Changeover
Quickly adjust the retract position on a conveyor sorting line to accommodate different large pallet sizes on the fly.
Press Stroke Tuning
Fine-tune the working stroke on a heavy-duty assembly press during commissioning to ensure precise contact without full mechanical impact.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-20 the Right Cylinder?
Choose this 160 mm bore when a 100 mm cylinder (providing 5497 N push at 0.7 MPa) lacks the thrust for your heavy fixtures, but a 200 mm bore would be physically excessive. The adjustable 930-950 mm travel window is perfect for machinery that requires exact end-position tuning during product changeovers, eliminating the need to swap out a fixed-stroke SAI cylinder. For any load-holding requirements without live air pressure, you must integrate an external pilot-operated check valve or switch to a SAIL locking cylinder.
Because the 950 mm stroke is substantial, the 40 mm rod diameter and M36x2 thread still require external guide rails to prevent excessive side-loading on the piston. To match this ISO 15552 footprint exactly, specify the 160 mm bore, 950 mm stroke, 20 mm adjustment, PT G3/4 port, and your required mounting style from the available SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2. Note that FB, CA, CB, and CR mounts are omitted from this adjustable series.

- ✓ 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 SAIJ160BX950-20 FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. It can reach a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the 950 mm nominal stroke by up to 20 mm, creating a 930-950 mm usable travel window. This stopper fine-tunes the end position but does not lock the load without live air pressure.
