About the Airtac SAIJ40 Adjustable Cylinder SAIJ40X1000-75
The AirTAC SAIJ40X1000-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 925-1000mm usable travel window, letting you dial back the nominal 1000mm stroke by up to 75mm during commissioning. Delivering 628N of push force at 0.5MPa, it uses a G1/4 port and a 16mm carbon steel rod.
This extruded aluminum profile cylinder includes sensor grooves on both sides and variable air cushions at both ends. The rear stopper acts purely as a travel end deceleration device, not a lock, so it cannot hold a load without live air pressure.

Where the Airtac SAIJ40 Adjustable Cylinder SAIJ40X1000-75 Is Used
Machine Changeover
Quickly reconfigure the 925-1000mm travel window for different product lengths on the same line without changing the physical cylinder setup.
End-Position Tuning
Fine-tune the exact retracted position during commissioning to dial in precise mechanical stops for long-stroke automated processes.
Material Handling
Drive long-travel pushers or diverters where the 628N force at 0.5MPa is sufficient, but the final stopping point requires on-site adjustment.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40X1000-75 the Right Cylinder?
Choose this 40mm bore when you need more force than a 32mm cylinder (402N push at 0.5MPa) but want a smaller footprint than a 50mm option (982N). The adjustable stroke is ideal for product changeovers, allowing you to fine-tune the end position without swapping the cylinder or bolting on external stops. For a fixed end position, a standard SAI cylinder is simpler.
Because this is a 1000mm stroke, the 16mm rod needs external guidance to prevent excessive side-loading. To match this ISO 15552 replacement exactly, specify the 40mm bore, 1000mm stroke, 75mm adjustment, PT port thread, and your required mounting from the SAIJ set (Basic, FA, LB, TC, FTC, TCM1, TCM2). No magnet is included, so position sensing is not supported.
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 SAIJ40 Adjustable Cylinder SAIJ40X1000-75 FAQ
At 0.5MPa operating pressure, this 40mm bore cylinder provides 628N of push force and 528N of pull force. At 0.7MPa, the push force increases to 879N.
The rear adjuster screw lets you shorten the effective stroke by up to 75mm, creating a 925-1000mm travel window. It acts as a mechanical stop to set the end position and does not lock the load without air pressure.
