About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X95-30S
The AirTAC SAIJ63X95-30-S is a double-acting ISO 15552 profile cylinder featuring a rear mechanical stroke adjuster. It provides a usable travel window of 65 to 95 mm, allowing you to dial back the nominal 95 mm stroke by up to 30 mm during commissioning. This bore size delivers 1559 N of push force and 1402 N of pull force at 0.5 MPa, making it well-suited for mid-range actuation tasks.
Equipped with a standard piston magnet, this unit supports AirTAC CMSE reed and DMSE electronic solid-state sensors housed within the dual-side extruded barrel grooves. The carbon steel rod with an M16x1.5 thread offers robust push connectivity, while the rear adjuster functions purely as an end-position stop and must not be relied upon to hold a load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X95-30S Is Used
Machine Changeover
Dial in the exact 65 to 95 mm end-stop during product size transitions without swapping hardware.
End-Position Calibration
Fine-tune the retract stroke by up to 30 mm at commissioning to perfect pressing or clamping depth.
Assembly Line Actuation
Leverage 1559 N of thrust at 0.5 MPa for mid-duty positioning tasks on automated production lines.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X95-30S the Right Cylinder?
Select this 63 mm bore when a 40 mm bore (628 N push @ 0.5 MPa) is insufficient but an 80 mm bore (2513 N push @ 0.5 MPa) would be excessive overkill. The 30 mm adjustable range is ideal for machinery requiring frequent product changeovers, eliminating the need to physically swap out a fixed-stroke SAI cylinder to achieve a different end-stop. Because the stroke is under 300 mm, side-load stress on the M16x1.5 rod is minimized, though external guidance is still recommended for heavy lateral loads.
For drop-in replacements, match the 63 mm bore, 95 mm nominal stroke, PT tapered port (G3/8), and the -S magnet requirement. Note that SAIJ supports a specific subset of ISO 15552 mounts: Basic, FA, LB, TC, FTC, TCM1, and TCM2. If your application requires the cylinder to maintain its position during a complete air loss, the standard adjuster will not act as a lock; you should instead evaluate the AirTAC SAIL or BSAI series.

- ✓ 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 SAIJ63X95-30S FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from the nominal 95 mm down to 65 mm, providing a 30 mm tuning window without changing the cylinder itself.
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 reach up to 2805 N push force at 0.9 MPa.
