About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X700-75S
The AirTAC SAIJ100X700-75-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 3927 N of push force at 0.5 MPa and features a 700 mm nominal stroke that can be fine-tuned down by up to 75 mm, yielding a usable travel window of 625-700 mm. This built-in adjustability allows you to dial in the exact retract end-position during commissioning without adding external stops.
Fitted with a PT tapered port and a magnetic piston for CMSE reed or DMSE electronic sensors, this extruded aluminum barrel cylinder handles speeds of 30-800 mm/s. The robust 25 mm carbon steel rod and M20x1.5 thread provide strong resistance to side loads, though a 700 mm stroke still requires an external guide to prevent rod bending. The rear adjuster acts purely as a travel stop, so live air is required to maintain the load position.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X700-75S Is Used
Variable End-Stop Positioning
Ideal for assembly stations requiring precise retract distances, using the 75 mm adjustment window to fine-tune the 625-700 mm travel without external mechanical stops.
Product Size Changeover
Enables quick line adjustments for varying package lengths, allowing operators to dial in the rear stroke position rapidly during product family transitions.
Heavy Fixture Calibration
Leverages the 3927 N push force at 0.5 MPa to move heavy machining fixtures, using the rear screw to set exact deceleration points during initial machine setup.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X700-75S the Right Cylinder?
Choose this 100 mm bore when a smaller 80 mm cylinder (providing 2513 N push at 0.5 MPa) lacks the thrust for heavy positioning tasks, but a 125 mm bore is oversized. The 75 mm adjustment window is ideal for production lines running mixed product sizes, letting operators change the retract endpoint on the fly instead of swapping out a fixed-stroke SAI cylinder. When matching your ISO 15552 footprint, specify the 100 mm bore, 700 mm stroke, 75 mm adjuster, PT port, and the -S magnet option.
Because the 700 mm stroke is relatively long, always support the load with an external linear guide to avoid damaging the rod. If your application requires true load-holding without constant air pressure, note that this cylinder's adjuster is a stop and not a lock; you should instead select an AirTAC SAIL or BSAI locking 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 SAIJ100X700-75S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. If you increase the pressure to 0.7 MPa, the push force rises to 5497 N.
The rear adjuster screw lets you shorten the 700 mm nominal stroke by up to 75 mm, creating a usable travel window of 625-700 mm. This allows you to set the exact retract end-position during commissioning without changing the cylinder.
