About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX240-30
The AirTAC SAIJ200X240-30 is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty applications requiring exact end-position tuning. It features a robust 200 mm bore generating 15708 N of push force at 0.5 MPa, alongside a rear adjuster that creates a usable travel window of 210-240 mm. This allows you to trim the effective stroke by up to 30 mm during commissioning without swapping hardware.
This unit is configured with a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and PT tapered port threads. It utilizes an extruded aluminum barrel with sensor grooves on both sides, operating at speeds of 30-500 mm/s. The rear stopper mechanism solely defines the travel end and deceleration point; it does not function as a lock, meaning live air pressure is required to hold the load.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX240-30 Is Used
Heavy Press Tuning
Dial in the exact 210-240 mm end position during heavy press commissioning to accommodate material thickness variations without adding external mechanical stops.
Product Line Changeover
Quickly adjust the stroke window on automated assembly lines when switching between different product sizes, minimizing downtime and maximizing throughput.
Large Load Positioning
Leverage the 15708 N push force to move massive fixtures, using the rear stopper to precisely set the retraction point within the 30 mm adjustment range.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX240-30 the Right Cylinder?
Select this 200 mm bore cylinder when an application demands substantial thrust, stepping up from a 160 mm bore that provides 10053 N at 0.5 MPa. The adjustable 210-240 mm window is ideal for product changeovers or fine-tuning machine setup, providing flexibility that a fixed-stroke SAI cylinder cannot offer. To match this exact ISO 15552 footprint for replacement, verify the 240 mm stroke, 30 mm adjustment range, PT port threads, and the specific mounting accessory (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
Because the 240 mm stroke is substantial and the piston rod diameter is 40 mm, ensuring adequate external guiding is critical to prevent excessive side-loading on the seal package. For any requirement involving load-holding without continuous air pressure, this standard adjuster will not suffice; instead, explore an external rod lock or pilot-operated check valve, or select a related SAIL or BSAI cylinder.
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 SAIJ200AX240-30 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder delivers 15708 N of push force and 15080 N of pull force. At a maximum 1.0 MPa, the push force reaches 3204 kgf.
The rear adjuster acts as a stopper that allows you to shorten the nominal 240 mm stroke by up to 30 mm, creating a usable travel window of 210-240 mm. It only sets the travel end and does not lock the load without live air pressure.
