About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX30-10S
The AirTAC SAIJ63X30-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 20-30 mm usable travel window by allowing you to dial back the 30 mm nominal stroke by up to 10 mm. Delivering a robust 1559 N push force at 0.5 MPa, it is equipped with a SUS420J2 stainless steel rod for superior corrosion resistance and uses PT tapered ports.
This adjustable-stroke design enables precise end-position tuning at commissioning without swapping the cylinder or adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches for position feedback. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX30-10S Is Used
Machine Setup Changeover
Dial in the exact 20-30 mm end-stop during product size changes without machining new hard stops or replacing the cylinder.
Clamping Position Trimming
Fine-tune the clamping travel on short-stroke fixtures to compensate for material thickness variations.
Sensor Calibration Rigs
Provides a variable physical stop for testing and calibrating proximity sensors within a tight 10 mm adjustment band.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX30-10S the Right Cylinder?
Choose this 63 mm bore model when a 1559 N thrust at 0.5 MPa is required for short, highly repeatable movements. If your application needs less force, stepping down to a 50 mm bore yields 982 N, while moving up to an 80 mm bore provides 2513 N. The adjustable rear stopper is ideal for machine setups requiring variable end-stops during product changeovers. For load-holding without continuous air pressure, this cylinder is insufficient since the adjuster is not a lock; consider the SAIL or BSAI series instead. To match this ISO 15552 replacement exactly, specify a 63 mm bore, 30 mm stroke, 10 mm adjustment, PT ports, and a -S magnet.
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 SAIJ63AX30-10S FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. It can deliver up to 318 kgf at its maximum 1.0 MPa pressure.
The rear adjuster screw allows you to shorten the 30 mm nominal stroke by up to 10 mm, creating a 20-30 mm usable travel window. This stopper only sets the end position; it does not lock or hold the load without continuous air pressure.
