About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X700-40
The AirTAC SAIJ100X700-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 700 mm travel that can be dialed back by up to 40 mm, yielding a 660-700 mm usable stroke window for precise end-position tuning. Delivering 3927 N of push force at 0.5 MPa, it handles heavy loads while maintaining standard ISO 15552 mounting dimensions.
This model incorporates a 25 mm carbon steel rod with an M20x1.5 thread, offering robust resistance to side loads, though a 700 mm stroke still requires an external guide to prevent rod bending. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic switches. Unlike fixed-stroke alternatives, this cylinder allows you to trim the retract position at commissioning without adding external stops or swapping the unit.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X700-40 Is Used
Machine Changeover
Dial in the 660-700 mm retract position during product size transitions without physically swapping the cylinder or reengineering the fixture.
Variable End-Stop Positioning
Trim the stroke by up to 40 mm to fine-tune where a diverter or pusher meets the conveyor flow, ensuring gentle product handling.
Heavy Load Actuation
Leverage 3927 N of thrust at 0.5 MPa to move heavy pallets or assemblies while maintaining precise end-position control.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X700-40 the Right Cylinder?
Select the 100 mm bore when the 80 mm variant (2268 N pull at 0.5 MPa) is insufficient for your payload. The SAIJ100X700-40 is chosen over a fixed SAI when a product line requires variable end-stops or fine-tuning during machine setup. The rear adjuster acts purely as a travel stop to set deceleration and end position, not as a lock; it will not hold the load without live air. For true position holding, consider an SAIL or BSAI cylinder.
As a dimensionally interchangeable ISO 15552 cylinder, it matches standard 100 mm bore, 700 mm stroke, PT tapered G1/2 port, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting interfaces. Because the stroke is 700 mm, always support the load with an external linear guide to prevent excessive side-load wear on the rod and seals.
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 SAIJ100X700-40 FAQ
At 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
A rear screw stopper lets you shorten the 700 mm stroke by up to 40 mm, creating a 660-700 mm travel window. This allows precise end-position tuning at commissioning without altering the air cushion or adding external stops.
