About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX120-10
The AirTAC SAIJ200X120-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 110 to 120 mm, allowing you to dial back the nominal 120 mm stroke by up to 10 mm during machine commissioning. Belonging to the 200 mm bore class, it delivers a robust push force of 15708 N and a pull force of 15080 N at 0.5 MPa, making it suitable for moving heavy industrial loads.
This variant features a SUS304 stainless steel piston rod for superior corrosion resistance and includes PT tapered port threads. The extruded aluminum barrel incorporates sensor grooves on both sides for flexible switch mounting. It operates at speeds from 30 to 500 mm/s and utilizes adjustable air cushions at both ends to decelerate the massive 40 mm diameter rod smoothly.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX120-10 Is Used
Machine Setup Tuning
Dial in the exact 110 to 120 mm end-position during initial commissioning without swapping out the entire cylinder or adding external stops.
Heavy Payload Shift
Leverage the 15708 N push force at 0.5 MPa to move heavy assemblies, using the rear stopper to absorb final position variations.
Product Changeover
Quickly adjust the travel window by up to 10 mm on packaging lines handling slightly different product sizes, minimizing downtime.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX120-10 the Right Cylinder?
Choose this 200 mm bore cylinder when your application requires extreme force—up to 15708 N at just 0.5 MPa. If your force requirements are lower, stepping down to a 160 mm bore provides 10053 N of push force, which may offer a more compact and economical footprint. The integrated 10 mm rear adjuster is ideal for fine-tuning the end-of-stroke position without adding external mechanical stops.
For any stroke length of 120 mm, the 40 mm rod handles high axial loads well, but long unsupported strokes still require an external guide to prevent side-loading damage. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for secure load-holding, consider the SAIL or BSAI series. This model is dimensionally interchangeable per ISO 15552 and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
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 SAIJ200BX120-10 FAQ
It delivers a push force of 15708 N and a pull force of 15080 N at 0.5 MPa. At 1.0 MPa, the maximum push force is 31904 N. The operating speed range is 30 to 500 mm/s.
The rear adjuster allows you to shorten the effective travel from the nominal 120 mm down to 110 mm, creating a 110-120 mm adjustable window. It acts as a mechanical stop to fine-tune the retract position and is not a locking device.
