About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X750-100S
The AirTAC SAIJ100X750-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 650 to 750 mm. Delivering 3927 N of push force at 0.5 MPa, it handles substantial pneumatic workloads. The integrated magnet supports position sensing via AirTAC CMSE reed and DMSE electronic switches.
This model features a robust 25 mm carbon steel rod with an M20x1.5 thread, paired with PT tapered port threading and a G1/2 air connection. The external rear stopper allows you to fine-tune the retract end position during commissioning or product changeovers without swapping the cylinder. It retains the standard extruded aluminum barrel with sensor grooves on both sides and uses adjustable air cushions at both ends to decelerate the load.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X750-100S Is Used
Variable End-Stop Positioning
Dial in the exact retract distance within the 650-750 mm window for product-size changeovers on long-stroke assembly lines without adding external stops.
Long-Stroke Forming Press
Utilize the 3927 N push force at 0.5 MPa for heavy forming tasks, relying on the adjustable air cushions to safely decelerate the large mass at stroke ends.
Extended Transfer Pusher
Push heavy pallets along a conveyor using the 25 mm carbon steel rod, adjusting the stroke by up to 100 mm to accommodate varying pallet dimensions.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X750-100S the Right Cylinder?
Choose this 100 mm bore when an 80 mm bore lacks sufficient thrust (the 80 mm yields 2513 N push at 0.5 MPa, whereas this 100 mm delivers 3927 N). The 100 mm adjustment range is ideal for machinery requiring variable end-stops across different product sizes, offering setup flexibility that a fixed-stroke SAI cannot match. Because the nominal stroke is 750 mm, an external guide is recommended to support the rod and prevent excessive side-loading on the bearing.
For a drop-in ISO 15552 replacement, match the 100 mm bore, 750 mm stroke, 100 mm adjust code, G1/2 port, PT thread, and the -S magnet option. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider an AirTAC SAIL or BSAI cylinder. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ100X750-100S FAQ
At 0.5 MPa operating pressure, 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.
The rear external stopper allows you to shorten the effective stroke by up to 100 mm, creating a usable travel window of 650 to 750 mm. The adjuster is a mechanical stop that sets the end position, not a lock, so continuous air pressure is required to hold the load.
