About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX75-50S
The AirTAC SAIJ160X75-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty positioning. It features a SUS304 stainless steel rod and a PT tapered port thread. With a 75 mm nominal stroke and a 50 mm adjustment range, you can dial the effective travel down to anywhere within a 25-75 mm window during commissioning without swapping hardware.
This bore size yields 10053 N of push force at 0.5 MPa and up to 18095 N at 0.9 MPa. The integrated -S magnet supports AirTAC CMSE reed and DMSE electronic sensors housed in the dual-side extruded barrel grooves. Note that the rear adjuster acts purely as a travel stop to decelerate the piston; it does not lock the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX75-50S Is Used
Heavy Press Tuning
Fine-tune the exact 25-75 mm end position during machine setup to accommodate different material thicknesses without replacing the cylinder.
Product Size Changeover
Rapidly adjust the stroke stop on automated lines when switching between large product variants, minimizing downtime.
Short-Stroke Forming
Leverage the 18095 N push force at 0.9 MPa for high-force forming tasks where precise lower-end travel limits are critical.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX75-50S the Right Cylinder?
Choose this 160 mm bore when 125 mm (8590 N push at 0.7 MPa) is insufficient but 200 mm (21991 N) would be excessive overkill. The 50 mm adjustment code is ideal for machinery requiring variable end-stops across short product sizes, replacing the need for fixed-stroke SAI cylinders and external mechanical stops. For load-holding without continuous air pressure, specify a SAIL pneumatic lock or BSAI clamp-lock cylinder instead of relying on the adjuster.
To match this ISO 15552 dimensionally interchangeable cylinder, confirm the 160 mm bore, 75 mm stroke, 50 mm adjustment, PT ports, SUS304 (B) rod, and -S magnet. Mounting is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 40 mm rod and M36x2 thread handle high side loads, ensure external guiding if the load geometry is asymmetrical.

- ✓ 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 SAIJ160BX75-50S FAQ
At 0.5 MPa it provides 10053 N push and 9425 N pull. At 0.9 MPa, the push force reaches 18095 N. The maximum rated force is 2050 kgf at 1.0 MPa.
The rear screw stopper lets you trim the 75 mm nominal stroke back by up to 50 mm, creating a usable travel window of 25-75 mm. It acts as a mechanical stop to set the end position and does not hold the load without air pressure.
