About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX50-10
The AirTAC SAIJ100X50-10 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 50 mm nominal stroke that can be fine-tuned backward by up to 10 mm, creating a precise 40-50 mm usable travel window for commissioning without external stops. Delivering a robust 3927 N push force at 0.5 MPa, it is built with a SUS304 stainless steel rod and tapered PT ports.
This adjustable-stroke model uses a mechanical stopper at the retract end to set the travel limit, meaning it does not hold the load without live air pressure. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to add CMSE reed or DMSE electronic sensors if position feedback is required later.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX50-10 Is Used
Press Fit Tuning
Dial in the exact 40-50 mm travel during assembly cell commissioning to guarantee precise pressing force without adding external mechanical stops.
Product Changeover
Quickly adjust the retract end-position by up to 10 mm on packaging lines when switching to a slightly shorter product format.
End-Stop Calibration
Use the rear adjuster to fine-tune the resting position of heavy actuators, ensuring perfect alignment with downstream machinery.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX50-10 the Right Cylinder?
Choose this 100 mm bore when an 80 mm bore (providing 2513 N at 0.5 MPa) is insufficient for your clamping or pressing requirements, but a 125 mm bore is oversized. The SAIJ100X50-10 is selected over a fixed SAI cylinder when you need to dial in the exact end-of-stroke position during machine setup or product changeover. To match this ISO 15552 interchangeable cylinder, specify the 100 mm bore, 50 mm stroke, 10 mm adjustment, PT ports, and your required mounting from the SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2. Because the 25 mm rod and M20x1.5 thread handle significant side loads, ensure your mounting arrangement supports the load properly.
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 SAIJ100BX50-10 FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
The rear adjusting screw acts as a mechanical stopper that shortens the 50 mm nominal stroke by up to 10 mm, giving a usable travel window of 40-50 mm. It sets the end position but does not lock or hold the load without live air pressure.
