About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX100-50S
The AirTAC SAIJ200X100-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 50 to 100 mm from its 100 mm nominal stroke. Delivering 21991 N of push force at 0.7 MPa, it handles heavy-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides, and this variant features a SUS304 stainless steel rod, PT tapered ports, and a magnet for CMSE or DMSE switches.
The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position during commissioning without adding external stops. It does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series. This model supports mounting accessories Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX100-50S Is Used
Heavy Press Tuning
Fine-tune the 50 to 100 mm retract stop on heavy pressing machinery to accommodate varying material thicknesses without changing the cylinder.
Product Changeover
Quickly adjust the end-stop position on automated assembly lines when switching between different product sizes, minimizing downtime.
Commissioning Calibration
Dial in the exact end position during initial machine commissioning using the rear adjuster, avoiding the need to bolt on external mechanical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX100-50S the Right Cylinder?
Choose this 200 mm bore cylinder when your application requires substantial thrust, such as 21991 N push at 0.7 MPa, alongside precise end-position tuning. If your force requirements are lower, stepping down to a 160 mm bore yields 14074 N push at 0.7 MPa. The adjustable stroke is ideal for machine setups requiring variable end stops during product changeovers rather than relying on a fixed-stroke SAI cylinder.
Because the 100 mm stroke is below the 300 mm threshold, side-load stress from an unsupported load is minimal, though the robust 40 mm rod and M36x2 thread handle high forces well. Ensure your ISO 15552 replacement matches the 200 mm bore, 100 mm stroke, 50 mm adjustment, PT ports, and the -S magnet requirement.
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 SAIJ200BX100-50S FAQ
At a 0.7 MPa operating pressure, this 200 mm bore cylinder generates 21991 N of push force and 15080 N of pull force. It can deliver up to 28274 N push force at 0.9 MPa.
The rear adjusting screw allows you to shorten the effective stroke by up to 50 mm. With a 100 mm nominal stroke, this provides an adjustable travel window between 50 and 100 mm. The adjuster functions as a travel stop and does not lock the load without live air pressure.
