About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX170-100S
The AirTAC SAIJ100X170-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 3927N of push force and 3681N of pull force at 0.5 MPa. The built-in stopper provides a generous 70-170mm usable travel window, allowing you to trim the nominal 170mm stroke by up to 100mm during machine commissioning without adding external stops.
This specific SKU features a SUS304 stainless steel rod (option B) for superior corrosion resistance and includes a magnet for position sensing. It uses a PT G1/2 tapered port and relies on adjustable air cushions at both ends to decelerate the load. The rear adjuster acts purely as a travel stop, so it will not hold a load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX170-100S Is Used
Variable End-Stop Tuning
Dial in the 70-170mm travel window precisely during setup to accommodate multiple product sizes on a single line without swapping cylinders.
Machine Changeover
Quickly shorten the effective stroke by up to 100mm at the rear screw during product format changes, eliminating the need to bolt on external physical stops.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod and 3927N push force to drive heavy positioning mechanisms in washdown or chemically exposed manufacturing areas.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX170-100S the Right Cylinder?
Choose this 100mm bore when an 80mm bore (2513N push at 0.5 MPa) is too weak, but you also need the flexibility to fine-tune the end-of-travel position on the fly. An adjustable stroke is ideal for product changeovers where the exact end-stop distance varies, unlike a fixed-stroke SAI cylinder. To replace an ISO 15552 cylinder, match the 100mm bore, 170mm stroke, 100mm adjustment, PT G1/2 port, and -S magnet. Because the 170mm stroke exceeds 300mm? No, but for any long stroke, ensure an external guide handles side loads. The 25mm rod and M20x1.5 thread handle high stress, but the adjuster is not a lock—use SAIL or BSAI for load-holding without live pressure.
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 SAIJ100BX170-100S FAQ
The rear adjusting screw lets you shorten the effective travel from the nominal 170mm down to a minimum of 70mm, providing a 100mm tuning window. It acts as a physical stop, so you must maintain live air pressure to hold the load.
This model includes a magnet (-S) for use with AirTAC CMSE reed switches and DMSE electronic solid-state sensors, which mount directly into the sensor grooves on both sides of the extruded aluminum barrel.
