About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X95-10
The AirTAC SAIJ63X95-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 85 to 95 mm, allowing you to dial back the nominal 95 mm stroke by up to 10 mm during commissioning without adding external stops. With a 63 mm bore, it delivers 1559 N of push force and 1402 N of pull force at 0.5 MPa.
This extruded aluminum barrel design incorporates sensor grooves on both sides and uses a G3/8 port. The carbon steel rod with an M16x1.5 thread handles side loads well, but you must guide long unsupported strokes externally. The rear adjuster acts purely as a travel stop for end-position tuning, not as a load-holding lock.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X95-10 Is Used
End-Stop Tuning
Dial in the exact 85 to 95 mm retract position during machine commissioning to perfect product placement without machining external stopper blocks.
Product Changeover
Quickly adapt the cylinder's effective stroke by up to 10 mm when running a slightly different package size on the same line.
Assembly Positioning
Use the micro-adjustability to set precise pressing or holding depths, ensuring consistent assembly quality across multiple cycles.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X95-10 the Right Cylinder?
Choose this 63 mm bore when your application requires approximately 1559 N of thrust at 0.5 MPa, stepping up from a 50 mm bore that provides 982 N. The 10 mm adjustment range is ideal for fine-tuning the retract end-position on product changeovers instead of swapping to a fixed-stroke SAI cylinder. Because the stroke is under 300 mm, side-load risks are moderate, though external guiding is still recommended for heavy lateral loads. To match this ISO 15552 footprint, specify the 63 mm bore, 95 mm stroke, 10 mm adjustment, PT tapered port threads, and standard carbon steel rod without a magnet. Remember that the SAIJ rear adjuster only sets the travel end and does not hold the load without live air; for true load-holding, select an SAIL or BSAI cylinder.
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 SAIJ63X95-10 FAQ
At an operating pressure of 0.5 MPa, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. At the maximum 1.0 MPa pressure, it provides up to 318 kgf of push force.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from the nominal 95 mm down to 85 mm. It sets the travel end for fine-tuning during setup, but it is not a lock and will not hold the load without continuous air pressure.
