About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX450-100S
The AirTAC SAIJ200X450-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a massive 3204 kgf maximum thrust at 1.0 MPa and features a usable travel window of 350-450 mm, letting you dial back the 450 mm nominal stroke by up to 100 mm. The barrel is extruded aluminum with sensor grooves on both sides, and this variant includes a magnet for position feedback alongside SUS420J2 stainless steel rod material and PT tapered port threads.
Because the rear adjuster acts purely as a mechanical stop, it decelerates the travel end alongside the variable air cushions but cannot hold a load without live air pressure. For true fail-safe load holding, you would need a related type like the SAIL (air-released lock) or BSAI (clamp-lock) rather than relying on the adjuster screw.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX450-100S Is Used
Heavy Press Fine-Tuning
Dial in the exact 350-450 mm end position for large pressing operations without changing out the entire cylinder setup.
Product Size Changeover
Quickly adjust the retract stop on a production line to accommodate varying large product dimensions during changeovers.
Machine Commissioning
Set precise end-position tuning at startup using the rear screw, avoiding the need to add external mechanical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX450-100S the Right Cylinder?
Choose this 200 mm bore when you need extreme thrust—stepping down to a 160 mm bore yields 2050 kgf, while this size delivers 3204 kgf at 1.0 MPa. The adjustable stroke is ideal for commissioning fine-tune or product-size changeovers, letting you shift the end position without swapping the cylinder or bolting on external stops. It uses PT tapered port threads and a G3/4 port.
When configuring your ISO 15552 replacement, match the 200 mm bore, 450 mm stroke, 100 mm adjustment, G3/4 port, and -S magnet. This SAIJ model uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR. Since the stroke is 450 mm, the 40 mm rod diameter and M36x2 thread carry high side loads, but long unsupported strokes still require an external guide to prevent binding.

- ✓ 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 SAIJ200AX450-100S FAQ
The rear adjusting screw lets you shorten the effective travel by up to 100 mm, creating a usable window of 350-450 mm from the 450 mm nominal stroke. The adjuster acts as a stop to set the end position and does not lock the load without live air.
It delivers a push force of 21991 N at 0.7 MPa and up to 3204 kgf (approximately 31392 N) at its maximum 1.0 MPa operating pressure.
