About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX200-100S
The AirTAC SAIJ200X200-100-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications requiring exact end-position tuning. It integrates a rear stroke adjuster that allows you to shorten the effective travel by up to 100 mm, creating a highly flexible 100-200 mm usable stroke window without changing the physical cylinder. Delivering immense thrust, it generates 21991N of push force and 15080N of pull force at 0.7 MPa. The piston features a SUS420J2 stainless steel rod and an integrated magnet for position sensing.
This adjustable model is built with a PT tapered port thread and a robust M36x2 rod thread. The extruded aluminum barrel includes sensor grooves on both sides, directly supporting AirTAC CMSE reed and DMSE electronic solid-state switches. The rear adjustment screw functions purely as a travel stop to dial in the exact retract position during commissioning; it does not lock or hold the load without live air pressure. For load-holding requirements, an external rod lock or related types like SAIL or BSAI are required.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX200-100S Is Used
Heavy Press Fine-Tuning
Dial in the exact 100-200 mm retract position on a large metal stamping press during setup, using the rear stopper to compensate for die wear without adding external mechanical stops.
Product Size Changeovers
Adjust the end-of-stroke position on the fly when a packaging line switches to a different pallet size, leveraging the 100 mm adjustment window to handle varied product dimensions.
Large Assembly Positioning
Move heavy automotive components into place with 21991N of force at 0.7 MPa, fine-tuning the final resting position during machine commissioning to ensure perfect alignment.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX200-100S the Right Cylinder?
Selecting this 200 mm bore adjustable-stroke cylinder makes sense when a machine requires variable end stops for product changeovers, avoiding the need to swap out fixed-stroke SAI cylinders or bolt on external stops. If your application requires less force, stepping down to a 160 mm bore yields 14074N of push force at 0.5 MPa, but the 200 mm bore is necessary for maximum thrust up to 3204 kgf at 1.0 MPa. When replacing an ISO 15552 cylinder, match the 200 mm bore, 200 mm nominal stroke, 100 mm adjustment range, PT ports, and the -S magnet requirement.
Because the stroke is 200 mm, which is below the 300 mm threshold requiring external guidance, the substantial M36x2 rod thread handles significant side loads, though an external guide rail is still recommended for heavy offset loads. Mounting options are limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR mounts found on other series. The operating speed is 30-500 mm/s, suited for moving large masses.
Quick checklist

- ✓ 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 SAIJ200AX200-100S FAQ
At 0.7 MPa, this 200 mm bore cylinder provides 21991N of push force and 15080N of pull force. It can reach a maximum thrust of 3204 kgf at 1.0 MPa, with an operating speed range of 30-500 mm/s.
The rear adjuster acts as a mechanical stop that lets you trim the effective stroke back by up to 100 mm from the nominal 200 mm, giving a usable travel window of 100-200 mm. It only sets the end position and does not hold the load without live air pressure.
