About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX105-10
The AirTAC SAIJ63X105-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 95-105 mm usable travel window, allowing you to dial in the exact end position without swapping hardware. Delivering 1559 N of push force at 0.5 MPa, it handles mid-range automation tasks with precision.
This variant features an SUS420J2 stainless steel rod (code A) for improved corrosion resistance compared to standard carbon steel. It uses PT tapered port threads (G3/8) and operates without a magnet. The rear screw acts purely as a mechanical stop to fine-tune the retract position, so it does not hold the load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX105-10 Is Used
Tooling Calibration
Micro-adjust the 95-105 mm travel window during machine setup to perfectly seat parts without adding external shims.
Product Changeover
Quickly reposition the end-stop on a packaging line when switching to a slightly different carton size.
Assembly Clamping
Apply 1559 N of clamping force at 0.5 MPa while allowing operators to tweak the exact clamping depth on the fly.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX105-10 the Right Cylinder?
Choose this 63 mm bore when a 50 mm cylinder (982 N push at 0.5 MPa) lacks thrust but an 80 mm bore (2513 N) is physically oversized. The 10 mm adjustment range is ideal for fine-tuning tooling distances during commissioning or product changeovers, avoiding the need to machine external stops. For load-holding without continuous air, select a SAIL or BSAI cylinder instead of relying on the adjuster.
To match this ISO 15552 interchangeable cylinder, specify: 63 mm bore, 105 mm stroke, 10 mm adjustment, PT G3/8 port, SUS420J2 rod, no magnet, and a mounting set limited to Basic, FA, LB, TC, FTC, TCM1, or 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 SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX105-10 FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
The rear adjuster screw lets you shorten the nominal 105 mm stroke by up to 10 mm, creating a 95-105 mm travel window. It functions as a mechanical stop for end-position tuning and is not a locking device.
