About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX100-30S
The AirTAC SAIJ63X100-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 70 to 100 mm. It delivers a robust 1559 N push force at 0.5 MPa, making it well-suited for mid-range actuation tasks. The extruded aluminum barrel features sensor grooves on both sides, and because this variant includes a magnet (-S), it integrates directly with AirTAC CMSE reed and DMSE electronic solid-state switches.
This model is factory-configured with an SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and uses PT tapered port threads with a G3/8 connection. The rear stopper allows you to fine-tune the end position during commissioning without adding external stops. Remember that this adjuster acts only as a travel stop to set deceleration; it does not hold the load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX100-30S Is Used
Changeover Calibration
Dial in the exact 70 to 100 mm end-stop during machine setup for different product sizes without swapping hardware.
Variable End Positioning
Trim the retract stroke precisely at commissioning to accommodate sensor feedback or mechanical tolerances.
Mid-Range Actuation
Leverage the 1559 N push force at 0.5 MPa for clamping or lifting tasks that require adjustable travel limits.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX100-30S the Right Cylinder?
Choose this 63 mm bore when a 50 mm bore (982 N push at 0.5 MPa) lacks the necessary thrust, but an 80 mm bore (2513 N push at 0.5 MPa) would be physically oversized. The 30 mm adjustment range is ideal for applications requiring variable end-stops or frequent product-size changeovers, offering flexibility that a fixed-stroke SAI cylinder cannot provide. If your process requires true load-holding without continuous air pressure, consider the SAIL or BSAI series instead.
To match this ISO 15552 dimensionally interchangeable cylinder, confirm the 63 mm bore, 100 mm nominal stroke, 30 mm adjustment range, G3/8 PT port, and magnet inclusion. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. The 20 mm rod diameter and M16x1.5 rod thread handle side loads well, though any unsupported travel should still use an external guide.
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 SAIJ63AX100-30S 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 acts as a mechanical stop, allowing you to shorten the effective travel from the 100 mm nominal stroke down to 70 mm. It sets the travel end and deceleration point but does not lock the load without live air.
