About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX650-100S
The AirTAC SAIJ160X650-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical adjuster, allowing you to trim the effective stroke within a 550 to 650 mm usable travel window. Utilizing a 160 mm bore, it delivers massive thrust up to 18095 N at 0.9 MPa, making it suitable for heavy-duty press and clamping operations. This unit includes a magnet for position sensing and features an SUS420J2 stainless steel rod for enhanced corrosion resistance.
The rear stopper screw enables precise end-position tuning during commissioning or product changeovers without swapping the cylinder or adding external stops. Because this is an extruded aluminum profile cylinder, it maintains standard ISO 15552 mounting dimensions while providing sensor grooves on both sides for flexible switch placement.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX650-100S Is Used
Heavy-Duty Press Fit
Dial in the exact 550-650 mm insertion depth for large bearings during automated press assembly, allowing precise tuning without mechanical retooling.
Product Size Changeover
Quickly adapt a packaging line to different pallet heights by adjusting the rear stopper, utilizing the 100 mm travel window for rapid format changes.
Variable End-Stop Clamping
Secure heavy structural components with up to 18095 N of force while fine-tuning the clamping position at commissioning to prevent material deformation.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX650-100S the Right Cylinder?
Choose this 160 mm bore when an 80 mm cylinder (providing 4523 N push force at 0.9 MPa) cannot meet your load requirements, but step down if that smaller force class suffices. The adjustable stroke is selected over a fixed SAI cylinder when a machine requires variable end-stops to accommodate different product sizes on the fly. To match this exact replacement, specify the 160 mm bore, 650 mm stroke, 100 mm adjustment, PT tapered port threads, SUS420J2 rod material, and the -S magnet option.
With a 650 mm stroke, the 40 mm diameter piston rod will experience leverage forces under load, so an external guide mechanism is recommended to prevent excessive side-loading. Note that the rear adjuster acts solely as a travel stop and does not hold the load without live air pressure; for true load-holding, consider an AirTAC SAIL or BSAI cylinder. The operating speed for this bore size is 30-500 mm/s.
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 SAIJ160AX650-100S FAQ
At an operating pressure of 0.9 MPa, this 160 mm bore cylinder generates a push force of 18095 N and a pull force of 14074 N. It can deliver a maximum push force of 10053 N at a standard 0.5 MPa.
The rear adjuster acts as a mechanical stop that allows you to shorten the 650 mm nominal stroke by up to 100 mm, providing a usable travel window of 550 to 650 mm. It is a travel stop for end-position tuning, not a lock, and cannot hold a load without continuous air pressure.
