About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-10S
The AirTAC SAIJ63X110-10-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers 1559N of push force at 0.5 MPa and provides a usable travel window of 100-110mm, letting you dial in the exact retract position without external stops. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This specific configuration features a SUS420J2 stainless steel rod (material code A) for improved corrosion resistance and carries the -S magnet option for position detection. It is designed to work seamlessly with AirTAC CMSE reed and DMSE electronic solid-state sensors. The integrated air cushions at both ends handle end-of-stroke deceleration, while the PT tapered port threads ensure a secure pneumatic connection.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-10S Is Used
Commissioning Calibration
Dial in the precise 100-110mm retract end-stop during initial machine setup to perfect alignment without machining custom spacers.
Product Changeover
Quickly adjust the stroke by up to 10mm on a packaging line when switching to a slightly different product size variant.
Machined Stop Positioning
Use the rear stopper to set a repeatable end-of-stroke limit for a clamping operation, relying on the 1559N thrust at 0.5MPa.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-10S the Right Cylinder?
Choose this 63mm bore when a 50mm cylinder (offering 982N push at 0.5MPa) lacks the necessary thrust, but an 80mm bore (2513N push) would be physically oversized. The 10mm adjustable window is ideal for fine-tuning end positions during machine commissioning or product changeovers, avoiding the need to physically swap out a fixed-stroke SAI cylinder. Note that the rear adjuster functions strictly as a travel stop and does not hold the load without live air; for true pneumatic locking, consider the SAIL or BSAI series.
When replacing an ISO 15552 cylinder, match the 63mm bore, 110mm stroke, 10mm adjustment range, PT port threads, and the -S magnet requirement. The SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. Operating speed ranges from 30-800mm/s.

- ✓ 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 SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-10S FAQ
At 0.5 MPa operating pressure, this 63mm bore cylinder provides 1559N of push force and 1402N of pull force. At 0.7 MPa, the push force increases to 2182N.
The rear adjuster acts as a mechanical stop that shortens the nominal 110mm stroke by up to 10mm, creating a 100-110mm usable travel window. It sets the end position but does not lock the load without continuous air pressure.
