About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX195-10S
The AirTAC SAIJ63X195-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 185 to 195 mm, allowing you to dial back the nominal 195 mm stroke by up to 10 mm during machine commissioning. Belonging to the 63 mm bore class, it generates 1559 N of push force and 1402 N of pull force at a 0.5 MPa operating pressure.
This specific SKU is configured with a SUS420J2 stainless steel rod for enhanced corrosion resistance and includes a piston magnet (-S) for position sensing. The barrel utilizes an extruded aluminum profile with sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic solid-state switches. Pneumatic connections use PT tapered threads, and the G3/8 port size matches the 63 mm bore's standard air flow requirements.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX195-10S Is Used
Machine Commissioning Tuning
Dial in the exact 185 to 195 mm end-of-stroke position during initial setup without machining external stopper blocks or changing the cylinder.
Product Size Changeover
Quickly adjust the retract stop by up to 10 mm on packaging lines when handling slightly shorter product lengths.
Sensor Position Calibration
Leverage the integrated magnet with DMSE electronic sensors while making precise rear stop adjustments to perfect timing cycles.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX195-10S the Right Cylinder?
Select this 63 mm bore model when your application requires 1559 N of thrust at 0.5 MPa, stepping up from a 50 mm bore that provides 982 N, or down from an 80 mm bore yielding 2513 N. The 10 mm adjustable stop is ideal for fine-tuning end positions on product changeovers without physically swapping the cylinder or adding external stopper blocks. For load-holding requirements without live air pressure, note that the rear adjuster acts only as a travel stop and does not function as a brake; you should instead consider an AirTAC SAIL or BSAI locking cylinder.
When replacing an ISO 15552 cylinder, match the 63 mm bore, 195 mm stroke, 10 mm adjustment range, G3/8 PT port, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR mounts found on some other series. Because the 195 mm stroke is below the 300 mm threshold, side-load concerns are minimal, but the 20 mm rod diameter and M16x1.5 rod thread still handle standard guiding duties well.
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 SAIJ63AX195-10S FAQ
At 0.5 MPa, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. It operates at speeds between 30 and 800 mm/s.
The rear adjuster screw acts as a mechanical stop that can shorten the effective travel by up to 10 mm, giving a usable stroke window of 185 to 195 mm. It does not lock the load without live air pressure.
