About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX500-40S
The AirTAC SAIJ160X500-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that lets you dial back the travel by up to 40 mm, creating a 460-500 mm usable window for exact end-position tuning. It delivers massive thrust, pushing 18095 N at 0.9 MPa, making it suited for heavy-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic switches.
This variant uses a SUS304 stainless steel rod for superior corrosion resistance and ships with a PT tapered port thread. The rear adjuster functions strictly as a travel stop to decelerate the stroke end, meaning it will not hold a load without live air pressure. For true load-holding, an external rod lock or the AirTAC BSAI clamp-lock series is required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX500-40S Is Used
Heavy Press Tuning
Dial in the exact 460-500 mm end-position during heavy press commissioning without installing external mechanical stops.
Product Changeover
Quickly adapt the stroke window on packaging lines when switching to different product sizes, saving setup time.
Corrosive Assembly
Leverage the SUS304 stainless steel rod for massive pushing force in washdown or mildly corrosive assembly environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX500-40S the Right Cylinder?
Choose this 160 mm bore when the 100 mm class (7068 N at 0.9 MPa) is insufficient for your heavy loads, but you want to avoid stepping up to the 200 mm bore. The adjustable stroke is ideal for machine changeovers, allowing you to fine-tune the 460-500 mm travel window without swapping the cylinder or adding external stops. Because the 500 mm stroke is substantial, always use an external guide to support the 40 mm rod and prevent excessive side-loading on the barrel.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 500 mm stroke, 40 mm adjustment, PT G3/4 port, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options found on other series.
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 SAIJ160BX500-40S FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder provides a push force of 18095 N and a pull force of 9425 N. It can reach a maximum push force of 10053 N at 0.5 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the 500 mm nominal stroke by up to 40 mm, providing a usable travel window of 460-500 mm. It only sets the end position and does not lock the load without air pressure.
