Airtac SAIJ100 Adjustable Cylinder SAIJ100BX160-100S
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100BX160-100S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 160mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX160-100S
The AirTAC SAIJ100X160-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 60-160 mm from its 160 mm nominal stroke. It delivers robust thrust, generating 3927N of push force at 0.5 MPa and up to 7068N at 0.9 MPa. The integrated -S magnet pairs directly with AirTAC CMSE reed and DMSE solid-state sensors via the dual-side barrel grooves.
Built for demanding environments, this variant features a SUS304 stainless steel rod (option B) for superior corrosion resistance. The PT tapered port threads match the G1/2 interface, while the 25 mm rod diameter and M20x1.5 thread provide excellent rigidity. The rear adjuster functions purely as a travel stop to dial in end positions during commissioning; it does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX160-100S Is Used
Variable End-Stop Tuning
Dial in the exact 60-160 mm travel distance during machine commissioning to accommodate different product lengths without replacing the cylinder.
Changeover Positioning
Rapidly adjust the retract end-position for product size changeovers on a packaging line, using the rear stopper instead of external mechanical stops.
Corrosive Assembly Lines
Leverage the SUS304 stainless steel rod in washdown or chemical environments while maintaining ISO 15552 mounting interchangeability.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX160-100S the Right Cylinder?
Choose this 100 mm bore adjustable-stroke model when a machine setup requires variable end-stops or frequent product-size changeovers without physically swapping the cylinder or adding external stops. If your application requires less force, stepping down to an 80 mm bore yields 2513N push at 0.5 MPa. For higher force, a 125 mm bore provides 6136N at 0.5 MPa.
Because the nominal stroke is 160 mm, an external guide is not strictly mandated for side-load support, but the 25 mm rod handles moderate lateral stress well. Remember that the rear adjuster and air cushions only decelerate the travel end; for true load-holding without live pressure, select a SAIL (air-released lock) or BSAI (clamp-lock) cylinder. To ensure exact ISO 15552 replacement, verify the 100 mm bore, 160 mm stroke, 100 mm adjustment, G1/2 PT port, and -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ100BX160-100S FAQ
At 0.5 MPa it provides 3927N of push force and 3681N of pull force. At 0.9 MPa, the push force increases to 7068N.
The rear adjuster acts as a mechanical stop that lets you trim the effective travel back by up to 100 mm from the 160 mm nominal stroke, creating a 60-160 mm usable window. It is a travel stop, not a lock, so it cannot hold the load without live air pressure.
