Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-30
The AirTAC Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø63mm bore and 160mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-30
The AirTAC SAIJ63X160-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 130-160 mm, allowing you to dial back the nominal 160 mm stroke by up to 30 mm. This bore size delivers a robust 1559 N push force at 0.5 MPa, making it suitable for medium-duty handling tasks.
The piston rod is equipped with an SUS420J2 stainless steel component (code A) for enhanced corrosion resistance, and the air supply connects via a PT tapered G3/8 port. Unlike fixed-stroke SAI units, this model lets you fine-tune the retract end-position at commissioning without adding external stops. The rear adjuster acts strictly as a travel stop for deceleration alongside the standard air cushions; it is not a lock, so the cylinder will not hold a load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-30 Is Used
Machine Changeover
Dial in the exact retract distance from 130 to 160 mm during product size transitions on a packaging line without swapping the cylinder.
End-Stop Tuning
Use the rear adjuster to set precise end-of-stroke positioning for medium-duty assembly tooling, avoiding the need for external mechanical stops.
Process Refinement
Adjust the travel window on the fly during commissioning to perfect the timing and deceleration of a 1559 N push operation.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-30 the Right Cylinder?
Choose this 63 mm bore adjustable cylinder when your application requires precise end-position tuning during machine setup or product changeover. If your process demands less force, stepping down to a 50 mm bore yields 982 N of push force at 0.5 MPa. Conversely, moving up to an 80 mm bore provides 2513 N for heavier loads. Because the 160 mm stroke is well under the 1500 mm maximum standard stroke, it ships as a standard catalog item.
When matching ISO 15552 dimensions for a replacement, verify the 63 mm bore, 160 mm nominal stroke, 30 mm adjustment range, PT G3/8 port, and the SUS420J2 rod material. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. For load-holding requirements without live air, consider the related SAIL or BSAI series instead of relying on the adjuster.

- ✓ 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 SAIJ63AX160-30 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 the maximum 1.0 MPa pressure, it can deliver up to 318 kgf.
The rear adjuster screw lets you shorten the effective stroke from its 160 mm nominal length down to 130 mm. This mechanism acts as a travel stop to set the end position and works with the air cushions for deceleration, but it does not lock or hold the load without continuous air pressure.
