About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX550-100S
The AirTAC SAIJ160X550-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 450 to 550 mm. It delivers 10053 N of push force at 0.5 MPa, making it suitable for heavy-duty positioning tasks. The barrel is extruded aluminum with sensor grooves on both sides, and this specific configuration includes a SUS420J2 stainless steel rod and a magnet for position detection.
Because the nominal 550 mm stroke falls within the 1500 mm standard limit for this bore, it is a catalog standard, yet the 100 mm adjustment range allows precise end-position tuning without external stops. The rear adjuster acts strictly as a travel stop and relies on the integrated air cushion for deceleration; it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX550-100S Is Used
Heavy Press Tuning
Dial in the exact 450-550 mm end position during heavy press commissioning without machining new hard stops.
Product Changeover
Adapt a conveyor diverter arm on the fly for varying pallet sizes using the 100 mm rear adjustment range.
Large Assembly Jigs
Securely position large automotive components with 10053 N of thrust while fine-tuning the clamping depth.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX550-100S the Right Cylinder?
Choose this 160 mm bore cylinder when an application requires substantial force, such as the 10053 N push thrust at 0.5 MPa, alongside a variable end-stop. If the project demands less force, stepping down to a 125 mm bore yields 6136 N, whereas moving up to a 200 mm bore provides 15708 N. The adjustable stroke is ideal for machine setups requiring frequent product changeovers, replacing the need to swap out a fixed-stroke SAI cylinder. When specifying the ISO 15552 replacement match, confirm the 160 mm bore, 550 mm stroke, 100 mm adjustment, PT tapered port threads, SUS420J2 rod material, and the -S magnet option.
Given the 550 mm stroke, the 40 mm rod diameter and M36x2 thread provide robust support, but an external guide is strongly recommended to manage side loads over this extended travel distance. The mounting hardware is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.
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 SAIJ160AX550-100S FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At 0.7 MPa, the push force increases to 14074 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 100 mm, creating a usable travel window of 450 to 550 mm. This stopper sets the end position but does not lock the load without continuous air pressure.
