About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX190-10
The AirTAC SAIJ63X190-10 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear mechanical adjuster. It delivers 1559 N of push force and 1402 N of pull force at 0.5 MPa, utilizing a G3/8 port. By turning the rear screw, you achieve a usable travel window of 180 to 190 mm, allowing precise end-position tuning without adding external stops.
This variant features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides. If position detection is later required, you can add AirTAC CMSE reed or DMSE electronic solid-state switches, though this specific SKU ships without a magnet.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX190-10 Is Used
Precision End-Stop Tuning
Dial in the exact 180 to 190 mm retract distance during machine commissioning to perfectly seat parts without relying on external shims.
Product Changeover
Quickly adjust the stroke by up to 10 mm on a packaging line when switching to a slightly different product size, minimizing downtime.
Machining Clamps
Fine-tune the clamping reach on a 63 mm bore actuator delivering up to 318 kgf at 1.0 MPa, ensuring parts are held securely without over-traveling.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX190-10 the Right Cylinder?
Choose this 63 mm bore when a 50 mm bore (982 N push at 0.5 MPa) is underpowered, but an 80 mm bore (2513 N push) would be excessive. The 10 mm adjustment range is ideal for applications needing minor commissioning tweaks rather than massive travel changes. Unlike a fixed-stroke SAI cylinder, this model lets you dial in the exact retract distance during machine setup.
Because the stroke is under 300 mm, side-load stress on the M16x1.5 rod thread is manageable, though external guides are always recommended for heavy loads. Remember that the rear adjuster functions strictly as a travel stop, not a locking device; the cylinder cannot hold a load without live air. For dead-air load holding, consider an AirTAC SAIL or BSAI cylinder. This unit is dimensionally interchangeable per ISO 15552 and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
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 SAIJ63AX190-10 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 its maximum 1.0 MPa pressure, it can deliver up to 318 kgf.
The rear adjuster acts as a mechanical stop, allowing you to shorten the 190 mm nominal stroke by up to 10 mm. This creates a 180 to 190 mm travel window for fine-tuning at commissioning, though it does not lock the position without continuous air pressure.
