About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX170-30S
The AirTAC SAIJ63X170-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 140-170 mm usable travel window, allowing you to trim the nominal 170 mm stroke by up to 30 mm during commissioning. Delivering 1559 N of pull force at 0.5 MPa, it handles robust actuation while utilizing a SUS420J2 stainless steel rod for enhanced corrosion resistance.
This variant includes a magnet for position sensing and is compatible with AirTAC CMSE reed and DMSE electronic solid-state switches. The extruded aluminum barrel features sensor grooves on both sides for flexible mounting. Unlike fixed-stroke SAI models, this cylinder allows precise end-position tuning without adding external stops or swapping the unit.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX170-30S Is Used
Machine Changeover
Dial in the 140-170 mm retract position precisely when switching between product sizes on a packaging line without changing cylinders.
End-Stop Tuning
Fine-tune the final end position during commissioning to avoid mechanical crashes, using the rear screw rather than external hard stops.
Robust Actuation
Leverage the 1559 N pull force and SUS420J2 stainless rod for durable pushing and pulling in general industrial automation.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX170-30S the Right Cylinder?
Choose this 63 mm bore when you need 1559 N pull force at 0.5 MPa, stepping up from a 50 mm bore that provides 825 N pull, or down from an 80 mm bore that yields 2268 N pull. The adjustable 140-170 mm window is ideal for product changeovers on a line, letting you fine-tune the retract end position on the fly. The PT tapered port threads match standard pneumatic fittings.
For any stroke of 170 mm, ensure external guides support the load if side loads are present, as the M16x1.5 rod thread handles moderate stress but cannot compensate for severe misalignment. The rear adjuster acts strictly as a travel stop and does not hold the load without live air; for pilot-operated locking, consider the SAIL or BSAI series. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and 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 SAIJ63AX170-30S FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of pull force and 2182 N of push force. At 0.7 MPa, the push force increases to 2182 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 30 mm, creating a usable travel window of 140 to 170 mm. The adjuster acts as a mechanical stop to set the retract position and does not lock the load without air pressure.
