About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X700-20
The AirTAC SAIJ100X700-20 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a robust 7068N of push force at 0.9 MPa, utilizing a 25mm carbon steel piston rod and a G1/2 PT tapered port. By integrating an external adjusting screw at the rear, this model establishes a precise 680-700mm usable travel window, allowing you to trim up to 20mm off the 700mm nominal stroke without adding external stops.
Designed for heavy-duty positioning, the extruded aluminum barrel includes sensor grooves on both sides for flexible CMSE reed or DMSE electronic switch mounting. It supports a standard mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2) while omitting FB, CA, CB, and CR configurations. The rear screw acts purely as a travel stop for end-position tuning and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X700-20 Is Used
Variable End-Stop Positioning
Dial in the exact retraction point between 680 and 700mm during machine setup to accommodate varying material thicknesses without mechanical redesign.
Automated Line Changeover
Rapidly adjust the stroke end-position by up to 20mm when switching between product variants on a high-thrust assembly line.
Heavy-Duty Clamping Setup
Leverage the 7068N push force at 0.9MPa to secure large workpieces, using the rear screw to fine-tune the clamping depth precisely.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X700-20 the Right Cylinder?
Select this 100mm bore when your application requires substantial thrust that exceeds the 4523N push force of an 80mm cylinder at 0.9 MPa, but falls short of needing the 11045N generated by a 125mm bore. The adjustable 680-700mm travel window is ideal for product-size changeovers, letting you fine-tune the retract end position at commissioning rather than swapping out a fixed-stroke SAI cylinder.
Because the 700mm stroke is substantial, the 25mm rod and M20x1.5 rod thread provide excellent rigidity, but an external guide is strongly recommended to prevent excessive side loading on the piston. For applications requiring true load holding without continuous live air, note that the rear adjuster is only a stop; you should instead evaluate the SAIL (air-released lock) or BSAI (clamp-lock) cylinder families.
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 SAIJ100X700-20 FAQ
At an operating pressure of 0.9 MPa, this 100mm bore cylinder generates a push force of 7068N and a pull force of 3681N. The maximum thrust is 801 kgf at 1.0 MPa.
The rear adjusting screw acts as an external stopper that lets you shorten the effective stroke by up to 20mm, creating a usable travel window of 680 to 700mm. It decelerates the travel end for fine-tuning but does not lock or hold the load without live air pressure.
