About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-75
The AirTAC SAIJ200X500-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 500 mm travel back by up to 75 mm. This creates a highly flexible 425-500 mm usable stroke window, letting you dial in the exact end position at commissioning without swapping out the barrel or adding bulky external stops. Built with an extruded aluminum barrel housing sensor grooves on both sides, it delivers massive thrust up to 15708 N at 0.5 MPa and 21991 N at 0.7 MPa.
This heavy-duty unit is configured with a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and features a robust M36x2 rod thread paired with G3/4 PT tapered ports. The 40 mm cushion length at both ends helps manage the kinetic energy of large loads moving within the 30-500 mm/s speed range. It supports AirTAC CMSE reed and DMSE electronic sensors via the integrated side grooves, providing reliable position feedback.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-75 Is Used
Heavy Press Tuning
Fine-tune the 425-500 mm travel window during heavy press commissioning to achieve precise bottoming force without re-engineering the machine frame.
Large Fixture Changeover
Adjust the end-stop rapidly when swapping out large product fixtures on a production line, accommodating varying part heights on the fly.
Variable Position Damping
Leverage the 40 mm air cushions alongside the rear stopper to safely decelerate massive 2805 kgf loads moving at up to 500 mm/s.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-75 the Right Cylinder?
Choose this 200 mm bore when your application requires extreme push force, stepping up from the 160 mm bore which provides 10053 N at 0.5 MPa. The adjustable rear stopper is ideal for heavy machinery setup and product changeover, allowing variable end-stops without machining new hard stops. However, the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for true load-holding, consider the SAIL (air-released lock) or BSAI (clamp-lock) series.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 500 mm stroke, 75 mm adjustment range, G3/4 PT ports, and the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting interfaces. Because the 500 mm stroke is substantial, the 40 mm diameter rod and M36x2 thread handle high stresses, but an external guide is strongly recommended to prevent side-load damage to the seal and bearing.
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 SAIJ200AX500-75 FAQ
At 0.5 MPa, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N, and it reaches a maximum of 3204 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that shortens the effective travel from the nominal 500 mm stroke. With the 75 mm adjustment range, you can set the usable stroke anywhere within a 425 mm to 500 mm window to fine-tune the retract end position.
