About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX200-10
The AirTAC SAIJ63X200-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the retract end-position by up to 10 mm. This creates a 190-200 mm usable travel window, letting you dial in the exact stop point at commissioning without adding external stops. It delivers a robust 2182 N push force at 0.7 MPa, making it suitable for moderate-to-heavy industrial positioning tasks.
The extruded aluminum barrel integrates dual sensor grooves, and the piston rod utilizes a SUS420J2 stainless steel construction for enhanced corrosion resistance. It connects via a PT tapered G3/8 port and relies on variable air cushions at both ends to decelerate the load. Remember that the rear adjuster acts only as a travel stop—it does not hold the load mechanically without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX200-10 Is Used
Machine Commissioning
Dial in the exact 190-200 mm retract position during setup without machining external stopper blocks.
Product Changeover
Quickly adapt the end-stop for slightly varying part sizes on a production line using the 10 mm trim.
End-Position Tuning
Compensate for mechanical wear or slight misalignment by adjusting the rear stopper rather than repositioning the cylinder.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX200-10 the Right Cylinder?
Choose this 63 mm bore cylinder when your application requires 2182 N of push force at 0.7 MPa and a small 10 mm commissioning window to perfect the end-stop. If you need less force, stepping down to a 50 mm bore yields 1374 N, while stepping up to an 80 mm bore provides 3518 N. The adjustable stroke is ideal for product changeovers where a fixed-stroke SAI cylinder would require shimming or swapping. For load-holding without continuous air pressure, consider the SAIL or BSAI series instead, as the SAIJ adjuster is not a lock. To match this ISO 15552 footprint, specify the 63 mm bore, 200 mm stroke, 10 mm adjustment, PT G3/8 port, and your required mounting from the SAIJ set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
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 SAIJ63AX200-10 FAQ
At 0.7 MPa, this 63 mm bore cylinder provides a push force of 2182 N and a pull force of 1402 N. It can deliver up to 2805 N push force at its maximum 1.0 MPa operating pressure.
The rear adjuster screw lets you shorten the effective stroke by up to 10 mm, creating a 190-200 mm usable travel window. It acts as a mechanical stop to set the end position, but it is not a lock and will not hold the load without live air pressure.
