About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX190-30
The AirTAC SAIJ63X190-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to shorten the effective travel by up to 30 mm. This yields a precise 160-190 mm usable travel window, enabling fine end-position tuning at commissioning without swapping the barrel or adding external stops. It delivers a robust 1559 N pull force at 0.5 MPa, making it ideal for moderate-to-heavy actuation tasks.
This unit uses a SUS420J2 stainless steel rod for superior corrosion resistance and features PT tapered port threading. The extruded aluminum barrel includes sensor grooves on both sides. Mounting options utilize the reduced SAIJ set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets. The rear adjuster acts solely as a travel stop to decelerate the end of stroke; it does not hold the load without live air.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX190-30 Is Used
Machine Changeover
Dial in the 160-190 mm travel window during product size changes to set new retract positions rapidly without swapping hardware.
Variable End-Stop
Use the 30 mm rear adjuster to fine-tune the end position during commissioning, preventing hard mechanical crashes.
Assembly Actuation
Leverage the 1559 N pull force at 0.5 MPa to securely seat components while trimming the final 30 mm of approach.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX190-30 the Right Cylinder?
Choose this 63 mm bore when a 50 mm bore yields insufficient thrust (982 N push at 0.5 MPa) but an 80 mm bore (2513 N push) is physically oversized. The 30 mm adjustment range is perfect for product changeovers on a line, allowing variable end-stops without installing a completely new cylinder. For load-holding without continuous air pressure, select a SAIL (air-released lock) or BSAI (clamp-lock) cylinder instead, as the SAIJ rear adjuster is not a locking mechanism. To match this ISO 15552 replacement exactly, verify the 190 mm stroke, 30 mm adjustment, PT G3/8 port, and standard mounting.
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 SAIJ63AX190-30 FAQ
At 0.5 MPa it provides 1559 N push and 1402 N pull force. At the maximum 1.0 MPa operating pressure, it delivers 318 kgf.
The rear adjuster acts as an external stopper that lets you shorten the 190 mm nominal stroke by up to 30 mm, creating a 160-190 mm usable travel window. It sets the retract end position but does not lock the load without live air.
