About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX450-10S
The AirTAC SAIJ200X450-10-S is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, delivering massive thrust up to 28274N at 0.9 MPa. It features an extruded aluminum barrel with sensor grooves on both sides and a SUS304 stainless steel rod for superior corrosion resistance. The integrated magnet enables position feedback via CMSE reed or DMSE electronic sensors.
This model provides a 440-450 mm adjustable travel window, allowing precise end-position tuning at commissioning without external stops. It uses a PT tapered G3/4 port and includes variable air cushions at both ends to manage heavy deceleration across its 30-500 mm/s speed range.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX450-10S Is Used
Heavy Pressing
Dial in the exact 440-450 mm end-stop for heavy pressing operations requiring precise position verification via DMSE sensors.
Machine Changeover
Fine-tune the retract position during product size changes without swapping the cylinder or adding external mechanical stops.
Variable End-Stop Setup
Use the 10 mm adjustment window to perfectly time the retraction point on large automated machinery during commissioning.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX450-10S the Right Cylinder?
Choose this 200 mm bore when your application requires extreme force, stepping up significantly from a 160 mm bore that yields 18095N push at 0.9 MPa. The 10 mm rear adjuster is ideal for fine-tuning the retract end during machine setup, whereas a fixed SAI cylinder locks you into a single 450 mm endpoint.
Because the nominal stroke is 450 mm, an external guide is recommended to prevent excessive side-loading on the M36x2 rod thread. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For true load-holding, select a SAIL or BSAI cylinder. This unit is dimensionally interchangeable with ISO 15552 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 SAIJ200 Adjustable Cylinder SAIJ200BX450-10S FAQ
At 0.9 MPa, this 200 mm bore cylinder provides a push force of 28274N and a pull force of 15080N. It reaches a maximum push force of 3204 kgf at 1.0 MPa.
The rear adjuster acts as an external stopper that lets you shorten the effective stroke by up to 10 mm, creating a 440-450 mm usable travel window. It is a travel stop, not a lock, and cannot hold the load without live air pressure.
