About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX145-10
The AirTAC SAIJ200X145-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the effective travel down to a 135-145 mm window. Delivering massive thrust, it provides 21991N of push force at 0.7 MPa and reaches 28274N at 0.9 MPa. The extruded aluminum barrel features sensor grooves on both sides for flexible positioning of CMSE reed or DMSE electronic switches.
This variant features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and uses PT tapered port threads. The rear adjustment screw acts purely as a mechanical stop to decelerate the piston at the end of travel, complementing the 50 mm variable air cushions at both ends. It is not a locking mechanism, meaning the cylinder cannot hold a load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX145-10 Is Used
Heavy Pressing
Fine-tune the 135-145 mm travel window to apply exact 28274N pressing force on large assemblies without over-traveling.
Changeover Setup
Quickly adjust the rear stop to accommodate slight variations in heavy product dimensions during line changeovers.
Robotic End Effector
Provides massive thrust for heavy lifting tasks, using the rear screw to safely set the retracted end position.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX145-10 the Right Cylinder?
Choose this 200 mm bore when your application requires extreme force that exceeds the 18095N push capacity of the 160 mm bore at 0.9 MPa. The 10 mm adjustable stroke is ideal for precision commissioning, letting you dial in the exact end position during product changeover without swapping the cylinder or adding external stops. For load-holding without continuous air pressure, consider the SAIL or BSAI series instead.
As a dimensionally interchangeable ISO 15552 cylinder, it replaces standard profile cylinders using a 200 mm bore, 145 mm stroke, PT G3/4 ports, and the SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the 145 mm stroke is relatively short for this massive bore, side-load stress is minimized, but an external guide is still recommended for heavy loads. The operating speed is 30-500 mm/s.
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 SAIJ200AX145-10 FAQ
At 0.9 MPa, this 200 mm bore cylinder generates 28274N of push force and 15080N of pull force. At 0.7 MPa, it provides 21991N of push force.
The rear adjuster screw lets you shorten the 145 mm nominal stroke by up to 10 mm, creating a 135-145 mm usable travel window. It acts as a mechanical stop for end-position tuning and does not lock the load without live air.
