About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX700-50S
The AirTAC SAIJ100X700-50-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 650 to 700 mm, letting you dial in the exact retract end-position during commissioning without adding external stops. Delivering 7068 N of push force at 0.9 MPa, it handles heavy positioning tasks with precision.
This unit includes a SUS304 stainless steel rod for corrosion resistance and a magnet for CMSE reed or DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the PT tapered ports ensure a tight pneumatic connection. It supports a speed range of 30-800 mm/s.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX700-50S Is Used
Variable End-Stop Positioning
Fine-tune the 650-700 mm travel window during machine setup to hit precise retract positions on large fixtures without machining new stop blocks.
Product Size Changeover
Quickly adapt a conveyor line for different part lengths by dialing the rear screw up to 50 mm, minimizing downtime between production runs.
Heavy-Duty Forming Press
Leverage the 7068 N push force at 0.9 MPa to drive large forming tools, using the adjustable stop to set the exact material engagement depth.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX700-50S the Right Cylinder?
Choose this 100 mm bore when a 63 mm bore (2182 N at 0.5 MPa) is insufficient for your load, but you want to avoid stepping up to a massive 125 mm body. The 50 mm adjustment window is ideal for product changeovers that require shifting the end-stop without swapping the cylinder. Because the stroke is 700 mm, an external guide is recommended to prevent side-load damage to the rod.
For ISO 15552 interchangeability, match the 100 mm bore, 700 mm stroke, 50 mm adjustment, G1/2 port, PT thread, and -S magnet. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, consider SAIL or BSAI cylinders.
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 SAIJ100 Adjustable Cylinder SAIJ100BX700-50S FAQ
At 0.9 MPa operating pressure, this 100 mm bore cylinder provides 7068 N of push force and 3681 N of pull force. At 0.5 MPa, the push force is 3927 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 50 mm, creating a 650-700 mm usable travel window. It only sets the travel end and does not lock the load without continuous air pressure.
