About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX120-10S
The AirTAC SAIJ200X120-10-S is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty tasks. It delivers 15708 N of push force and 15080 N of pull force at 0.5 MPa, featuring a robust 40 mm SUS304 stainless steel rod. A rear-mounted stroke adjuster allows you to fine-tune the travel end-point, providing a usable window of 110-120 mm for precise commissioning without external stops.
This model includes a built-in magnet for position sensing via CMSE reed or DMSE electronic switches mounted in the dual-side sensor grooves. It features PT tapered port threads (G3/4) and a 50 mm adjustable air cushion at both ends to manage kinetic energy. The rear adjuster acts purely as a travel stop for end-position tuning and does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX120-10S Is Used
Heavy Press Fine-Tuning
Dial in the exact end-position of a high-force pressing or stamping station within the 110-120 mm window during initial commissioning without adding external mechanical stops.
Product Changeover
Quickly adjust the rear stopper by up to 10 mm to accommodate slightly different product heights on a heavy-duty assembly line, maximizing setup flexibility.
Robust End-Stop Positioning
Leverage the 15708 N push force and SUS304 rod for positioning heavy materials, relying on the rear stop to precisely set the retraction end-point.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX120-10S the Right Cylinder?
Select this 200 mm bore actuator when your application requires immense thrust, such as 15708 N at 0.5 MPa, which far exceeds the 10053 N push force of the neighbouring 160 mm bore. The 10 mm adjustable stroke range is ideal for dialing in exact end-positions during machine setup or product changeover, avoiding the need to physically swap out a fixed-stroke SAI cylinder. To match this ISO 15552 interchangeable cylinder, specify the 200 mm bore, 120 mm stroke, 10 mm adjustment, PT G3/4 ports, SUS304 rod, and the -S magnet for sensing. Because the stroke is 120 mm, side-load risks are minimal, but always ensure the mountings from the available set (Basic, FA, LB, TC, FTC, TCM1, TCM2) are correctly aligned. For load-holding without continuous air, use an external rod lock or pilot-operated check valve, as the adjuster is not a brake.
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 SAIJ200BX120-10S FAQ
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At the maximum pressure of 1.0 MPa, it delivers up to 3204 kgf.
The rear adjuster screw allows you to shorten the nominal 120 mm stroke by up to 10 mm, creating a usable travel window of 110-120 mm. This stopper sets the retract end-position for fine-tuning but does not lock or hold the load without live air pressure.
