About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-75S
The AirTAC SAIJ200X500-75-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa, making it suitable for heavy-duty industrial tasks. The integrated -S magnet allows direct mounting of CMSE reed and DMSE electronic solid-state sensors in the dual-side barrel grooves. This variant features a SUS420J2 stainless steel rod (code A) and PT tapered port threads.
With a nominal 500 mm stroke and a 75 mm adjustment range, the usable travel window is 425-500 mm. This external rear stopper allows precise end-position tuning during commissioning or product changeover without adding external stops. The adjuster acts solely as a travel stop and deceleration aid, not a lock, so live air pressure is required to hold the load.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-75S Is Used
Heavy Press Tuning
Dial in the exact 425-500 mm end-position on a large metal forming press during setup, ensuring precise crimping depths without swapping out the entire cylinder body.
Pallet Diversion
Adjust the retract stroke on a heavy pallet diverter arm to handle different pallet lengths on the same conveyor line quickly during product changeover.
Large Fixture Stops
Provide a variable hard stop for large automotive sub-assemblies, tweaking the 75 mm window to dial in the exact resting position for various part models.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-75S the Right Cylinder?
Choose this 200 mm bore when 160 mm (10053 N push at 0.5 MPa) is insufficient for your heavy machinery setup. An adjustable stroke is selected over a fixed SAI when you need variable end-stops to accommodate multiple product sizes on the same line. For load-holding without continuous air pressure, this cylinder will not suffice; instead, consider the SAIL or BSAI locking series, or an external rod lock. To replace an ISO 15552 cylinder, match the 200 mm bore, 500 mm stroke, 75 mm adjustment, PT G3/4 port, and Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting interface.
Because the 500 mm stroke is long and the 40 mm rod with M36x2 thread carries high side loads, you must use an external guide rail to prevent rod binding and premature seal wear. The operating speed is 30-500 mm/s, and the cylinder uses 50 mm variable air cushions at both ends to absorb kinetic energy.
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 SAIJ200AX500-75S FAQ
At 0.5 MPa it provides 15708 N of push force and 15080 N of pull force. At the maximum operating pressure of 1.0 MPa, the push force reaches 28274 N.
The rear adjuster screw lets you shorten the effective travel from 500 mm down to 425 mm. It functions as a mechanical stop for end-position tuning, but it is not a lock and cannot hold the load without live air pressure.
