About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX200-50S
The AirTAC SAIJ200X200-50-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers immense thrust, providing 15708N push force at 0.5 MPa and up to 28274N at 0.9 MPa. The integrated -S magnet enables precise position detection using AirTAC CMSE reed or DMSE electronic solid-state sensors housed within the dual-side barrel grooves. A SUS420J2 stainless steel rod (code A) provides enhanced corrosion resistance for demanding environments.
With a nominal 200mm stroke and a 50mm adjustment range, this model provides a usable travel window of 150-200mm. This allows operators to dial in the exact retract end-position during commissioning without swapping out the entire cylinder. The PT tapered port threads ensure a high-integrity pneumatic seal, while the extruded aluminum profile maintains strict ISO 15552 dimensional interchangeability.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX200-50S Is Used
Heavy Press Tuning
Fine-tune the 150-200mm travel window during heavy press commissioning to achieve exact material contact without adding external mechanical stops.
Product Changeover
Quickly adjust the retract end-position on a conveyor sorting arm to accommodate different package sizes on the fly.
Variable End-Stop Actuation
Dial in the precise stroke length for heavy-duty automated machinery setups where the final position varies per production run.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX200-50S the Right Cylinder?
Selecting this 200mm bore cylinder is appropriate when an application requires upward of 15708N push force at 0.5 MPa; stepping down to a 160mm bore would reduce that output to 10053N. The adjustable 150-200mm travel window is chosen over a fixed-stroke SAI cylinder when a machine requires variable end-stops or frequent product-size changeovers. To replace an ISO 15552 cylinder, match the 200mm bore, 200mm stroke, 50mm adjustment, G3/4 port, and -S magnet.
Because the stroke is 200mm, supporting the load with an external guide is recommended to prevent excessive side-loading on the 40mm rod. Note that the rear adjuster functions strictly as a travel stop and does not hold the load without live air; for true load-holding without pneumatic pressure, consider an AirTAC SAIL or BSAI cylinder. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ200AX200-50S FAQ
At 0.5 MPa it provides 15708N of push force and 15080N of pull force. At 0.9 MPa, the push force increases to 28274N.
The rear adjuster acts as a mechanical stop that lets you trim the effective stroke back by up to 50mm, creating a usable travel window of 150-200mm from the 200mm nominal stroke. It only sets the travel end and does not lock the load without live air.
