Airtac SAIJ100 Adjustable Cylinder SAIJ100BX700-20
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100BX700-20 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 700mm 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 SAIJ100BX700-20
The AirTAC SAIJ100X700-20 is a double-acting ISO 15552 profile cylinder featuring a SUS304 stainless steel rod and a rear mechanical stroke adjuster. It provides a robust 3927N push force at 0.5MPa and a usable travel window of 680-700mm, letting you trim the retract end-position by up to 20mm during commissioning without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches if a magnet is added later.
This model uses a G1/2 port and omits the FB, CA, CB, and CR mounting styles found on some variants, offering a focused set of ISO 15552 interfaces (Basic, FA, LB, TC, FTC, TCM1, TCM2). The rear adjuster acts purely as a travel stop and works alongside the standard air cushions to decelerate the load; it does not hold the load without live air pressure. For position-holding requirements without continuous air, consider the SAIL or BSAI series.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX700-20 Is Used
Machine Setup Calibration
Dial in the exact retract position of a heavy press during initial commissioning, using the 20mm adjuster to compensate for mechanical tolerance stack-up without machining spacers.
Product Changeover
Quickly adapt a long-stroke diverting arm on a packaging line for different carton sizes by adjusting the travel window down to 680mm for the new format.
Long-Stroke Material Handling
Drive heavy workpieces across a 700mm span using 3927N of push force, relying on the built-in air cushions and rear stopper to smoothly decelerate the load.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX700-20 the Right Cylinder?
Choose this 100mm bore when your application requires substantial thrust—up to 3927N push and 3681N pull at 0.5MPa. If your force requirements are lower, stepping down to an 80mm bore yields 2513N push, while moving up to a 125mm bore provides 6136N. The 20mm adjustment range is ideal for fine-tuning long-stroke machinery setups where a fixed 700mm SAI cylinder might leave you shimming external stops. To replace an ISO 15552 cylinder, match the 100mm bore, 700mm stroke, 20mm adjustment, PT tapered G1/2 port, and the desired mounting kit.
Because the stroke is 700mm, the M20x1.5 rod and piston assembly are subject to increased side-loading when fully extended. Even with the durable SUS304 rod material, an external guide rail should be used to support the load and prevent premature seal wear. The cylinder operates efficiently at speeds between 30-800mm/s.
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 SAIJ100BX700-20 FAQ
At an operating pressure of 0.5MPa, the SAIJ100X700-20 provides 3927N of push force and 3681N of pull force. At 0.7MPa, the push force increases to 5497N.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke from 700mm down to 680mm. It allows fine-tuning of the end position during setup but does not lock the load in place without continuous air pressure.
