About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX900-100
The AirTAC SAIJ160X900-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the nominal 900 mm travel by up to 100 mm. This yields a usable end-position window of 800-900 mm, letting you fine-tune the retract distance during commissioning without swapping out the unit. It delivers robust thrust, generating 10053 N of pull force at 0.5 MPa and up to 18095 N of push force at 0.9 MPa.
Equipped with a SUS304 stainless steel rod, this configuration offers superior corrosion resistance for harsh environments. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to mount CMSE reed or DMSE solid-state switches if needed later. As a true profile cylinder, it shares the exact ISO 15552 mounting interface of standard fixed-stroke units but adds external mechanical stop flexibility.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX900-100 Is Used
Variable End-Stop Calibration
Dial in the exact retract distance between 800 and 900 mm during machine setup to accommodate different material thicknesses without changing the cylinder.
Product Changeover Systems
Quickly adjust the stroke length on packaging lines when switching to a new product size, using the 100 mm trim window to hit the new position.
Heavy-Duty Positioning
Leverage the 18095 N push force at 0.9 MPa to move heavy pallets or tooling, relying on the SUS304 rod for durability in washdown environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX900-100 the Right Cylinder?
Select this 160 mm bore when an 80 mm bore (2268 N pull at 0.5 MPa) cannot provide enough force, but a 200 mm bore (15080 N pull at 0.5 MPa) would be physical overkill. The adjustable stroke is specifically chosen when you need variable end-stops for product changeovers on a line, avoiding the need to bolt on external stops or buy multiple fixed-stroke SAI cylinders. The PT tapered port and G3/4 thread size match the standard 160 mm bore specifications.
Because the stroke is 900 mm, the long unsupported piston rod requires an external guide to prevent excessive side-loading and premature seal wear. Note that this cylinder does not hold its load without live air pressure; the rear adjuster is a travel stop, not a lock. For true fail-safe load holding, consider the SAIL (air-released lock) or BSAI (clamp-lock) series instead. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ160BX900-100 FAQ
The rear of the cylinder features an external adjusting screw that acts as a mechanical stopper. It allows you to shorten the effective stroke by up to 100 mm from the 900 mm nominal length, providing an 800-900 mm travel window for fine-tuning at commissioning.
At 0.5 MPa it provides 10053 N pull force and 14074 N push force. At 0.9 MPa, the push force increases to 18095 N, with a maximum rated force of 2050 kgf at 1.0 MPa.
