About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX500-40
The AirTAC SAIJ160X500-40 is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical adjuster, allowing you to trim the effective stroke within a 460-500mm usable travel window. Delivering massive thrust, it provides 18095N of push force at 0.9 MPa and 14074N at 0.7 MPa. The extruded aluminum barrel features sensor grooves on both sides for flexible switch placement.
This unit features a robust 40mm SUS304 stainless steel rod (material code B) and a PT tapered port thread. The rear stopper screw sets the end position but does not function as a lock, meaning live air pressure is required to hold the load. For position holding without air, consider the SAIL or BSAI series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX500-40 Is Used
Heavy Press Tuning
Fine-tune the exact end position of high-tonnage pressing operations during commissioning without adding external mechanical stops.
Product Changeover
Adjust the 460-500mm travel window on packaging lines to accommodate different carton sizes quickly and accurately.
Large Assembly Setups
Dial in the precise extension length for heavy fixture alignment in automated automotive assembly equipment.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX500-40 the Right Cylinder?
Choose this 160mm bore when an 80mm cylinder (4523N push at 0.9 MPa) lacks the power for heavy positioning tasks, or step up to a 200mm bore (28274N at 0.9 MPa) if your load exceeds 18095N. The adjustable stroke is ideal for product changeovers, letting you fine-tune the end stop without swapping cylinders. Because the 500mm stroke is substantial, always use an external guide to prevent excessive side-loading on the rod.
To match this ISO 15552 interchangeable cylinder, specify a 160mm bore, 500mm stroke, 40mm adjustment range, PT ports, and SUS304 rod. It supports the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and operates at 30-500mm/s. As no magnet is specified, it will not work with CMSE or DMSE sensors.
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 SAIJ160BX500-40 FAQ
At 0.9 MPa it provides 18095N of push force and 14074N at 0.7 MPa. The maximum thrust at 1.0 MPa is 2050 kgf.
The rear adjuster acts as a mechanical stop, allowing you to shorten the 500mm nominal stroke by up to 40mm, creating a 460-500mm usable travel window. It only sets the end position and does not lock the load without live air.
