About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX170-10S
The AirTAC SAIJ100X170-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 3927N push force at 0.5MPa, stepping up to 7068N at 0.9MPa. The built-in -10mm adjustment screw creates a precise 160-170mm usable travel window, allowing you to fine-tune the retract end position during commissioning without swapping out the entire actuator.
This variant features a SUS304 stainless steel rod (code B) for superior corrosion resistance and carries the -S magnet option for seamless integration with AirTAC CMSE reed and DMSE electronic sensors. Fluid ports are PT threaded, and the extruded aluminum barrel includes sensor grooves on both sides. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX170-10S Is Used
Machine Setup & Changeover
Dial in the 160-170mm travel window during product line changeovers to perfectly position heavy clamps without machining new hard stops.
Variable End-Stop Positioning
Trim the retract stroke by up to 10mm to accommodate slightly different package sizes on a conveyor sorting system.
Heavy-Duty Forming Press
Leverage the 7068N push force at 0.9MPa to form metal components while using the rear screw to fine-tune the bottoming depth.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX170-10S the Right Cylinder?
Select this 100mm bore actuator when an application requires heavy thrust that a 80mm bore (2513N push at 0.5MPa) cannot provide, but without stepping up to a 125mm unit (6136N). The 10mm rear adjuster is ideal for dialing in exact end-stops during machine setup or product changeover, replacing the need for external stops. Because the stroke is 170mm, side-load stress is moderate, but external guides should still be used for optimal rod bearing life.
To match this ISO 15552 dimensionally interchangeable cylinder, confirm the 100mm bore, 170mm nominal stroke, PT ports, and the -S magnet. Remember that the rear adjuster functions strictly as a travel stop and does not hold the load without live air; for true pneumatic locking, consider the SAIL or BSAI series.
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 SAIJ100 Adjustable Cylinder SAIJ100BX170-10S FAQ
The rear adjusting screw acts as a mechanical stopper that allows you to shorten the effective stroke by up to 10mm, providing a usable travel window of 160-170mm. It sets the end position but does not lock the load without continuous air pressure.
At 0.5MPa operating pressure, it provides 3927N of push force and 3681N of pull force. At 0.9MPa, the push force increases to 7068N.
