About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX150-50S
The AirTAC SAIJ63X150-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the retract end-position. It provides a usable travel window of 100-150 mm, enabling rapid product changeovers without swapping hardware. The bore delivers 1559 N of pull force at 0.5 MPa and 2182 N of push force at 0.7 MPa.
This variant includes a magnet for position sensing with AirTAC CMSE reed or DMSE electronic switches. It uses a SUS420J2 stainless steel rod for corrosion resistance and features PT tapered port threads (G3/8). The extruded aluminum barrel includes sensor grooves on both sides, and mounting options span Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX150-50S Is Used
Variable End-Stop Machining
Dial in the exact 100 to 150 mm clamping depth for different material thicknesses directly at the machine without adding external stopper blocks.
Product Size Changeover
Quickly adjust the retract position on packaging lines when switching to a new carton size, keeping downtime to a minimum.
Commissioning Fine-Tuning
Trim the effective stroke by up to 50 mm during setup to perfectly time machine sequencing and prevent mechanical interference.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX150-50S the Right Cylinder?
Choose this 63 mm bore if your application requires around 1559 N pull force at 0.5 MPa. Stepping up to an 80 mm bore yields 2268 N pull, while dropping to a 50 mm bore provides 825 N. The 50 mm adjustment range is ideal for machines processing variable product sizes, replacing the need to inventory multiple fixed-stroke SAI cylinders.
For stroke lengths of 150 mm, the M16x1.5 rod handles moderate side loads, but an external guide is recommended for heavy offset loads. This cylinder does not hold loads without live air; the adjuster is a stop, not a lock. For fail-safe holding, use an external rod lock or a BSAI clamp-lock cylinder. It is dimensionally interchangeable per ISO 15552.
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 SAIJ63AX150-50S FAQ
A rear adjusting screw acts as a mechanical stop, allowing you to shorten the nominal 150 mm stroke by up to 50 mm. This creates a usable travel window of 100 to 150 mm, but it only sets the end position; it does not lock or hold the load without live air pressure.
At a 0.5 MPa operating pressure, it provides 2182 N of push force and 1559 N of pull force. At 0.7 MPa, the push force increases to 2805 N.
