Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-100S
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-100S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 190mm 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 SAIJ100BX190-100S
The AirTAC SAIJ100X190-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 190 mm nominal stroke that can be dialed back by up to 100 mm, providing a wide 90-190 mm usable travel window for precise end-position tuning. In the push direction, it generates 3927 N of force at 0.5 MPa and reaches a maximum of 801 kgf at 1.0 MPa.
This variant includes a SUS304 stainless steel rod (code B) for superior corrosion resistance and uses PT tapered ports sized at G1/2. The extruded aluminum barrel incorporates sensor grooves on both sides, and because this unit includes a magnet (-S), it directly supports AirTAC CMSE reed and DMSE electronic solid-state switches. The rear adjuster acts strictly as a travel stop to set deceleration, not as a lock to hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-100S Is Used
Product Changeover
Dial the rear stopper back by up to 100 mm to accommodate different product lengths on the same line without physically changing out the cylinder.
Commissioning Setup
Fine-tune the 90-190 mm travel window during initial machine commissioning to achieve perfect end-positioning without adding external shims.
Variable End Stops
Ideal for automated assembly lines where the final pressing or pushing distance needs occasional adjustment to adapt to varying material thicknesses.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-100S the Right Cylinder?
Choose this 100 mm bore when an 80 mm bore (delivering 2513 N push force at 0.5 MPa) is insufficient for your load, but a 125 mm bore is too large. An adjustable stroke is ideal for machine setups requiring variable end-stops or frequent product-size changeovers, allowing you to fine-tune the 90-190 mm travel window without swapping the cylinder or adding external stops. Unlike a fixed-stroke SAI, this model grants flexibility directly at commissioning.
For a drop-in ISO 15552 replacement, match the 100 mm bore, 190 mm stroke, 100 mm adjustment code, PT port threads, and the -S magnet. Mounting options are limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Because the stroke is under 300 mm, side-load stress is moderate, but the robust 25 mm rod and M20x1.5 thread help handle higher off-center loads. If your application requires holding a load without continuous air pressure, use a SAIL air-released lock or BSAI clamp-lock instead of relying on the adjuster.
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 SAIJ100BX190-100S FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At its maximum 1.0 MPa pressure, it delivers up to 801 kgf of push force.
The rear adjusting screw acts as a mechanical stop, allowing you to shorten the 190 mm nominal stroke by up to 100 mm. This creates a usable travel window of 90-190 mm; however, it functions only as a travel stop and does not lock or hold the load without live air pressure.
