About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX290-75S
The AirTAC SAIJ200X290-75-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications requiring exact end-position tuning. Equipped with a rear stopper screw, it transforms the 290 mm nominal stroke into a 215-290 mm usable travel window. This allows operators to dial back the extension distance at commissioning without swapping hardware or adding external stops. It delivers 15708 N of push force at 0.5 MPa and reaches a maximum of 3204 kgf at 1.0 MPa.
Built for demanding environments, this unit features a SUS420J2 stainless steel rod (code A) for superior corrosion and wear resistance. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet supports position feedback via AirTAC CMSE reed switches or DMSE solid-state electronic sensors. Fluid ports are PT tapered G3/4 threads, and the variable air cushions at both ends decelerate the massive 40 mm rod to prevent end-cap impact.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX290-75S Is Used
Variable End-Stop Positioning
Ideal for large presses where the rear 75 mm adjuster fine-tunes the 290 mm stroke window to accommodate different material thicknesses without repositioning the entire cylinder assembly.
Heavy Machinery Changeover
The 15708 N push force at 0.5 MPa handles massive industrial loads, while the external stopper allows quick travel adjustments during production line changeovers to new product dimensions.
Large-Scale Alignment
Perfect for aligning heavy structural components, offering a 215-290 mm adjustable travel window and a SUS420J2 stainless steel rod that withstands harsh industrial environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX290-75S the Right Cylinder?
Select this 200 mm bore when your application requires substantial thrust—stepping down to a 160 mm bore drops the 0.5 MPa push force to 10053 N, whereas this SAIJ200X290-75-S provides 15708 N. The 75 mm adjustment range is ideal for machinery undergoing frequent product changeovers, allowing the end-stop to be fine-tuned to match varying package sizes on the fly. For operations needing load holding without live air pressure, note that the rear adjuster is strictly a travel stop, not a lock; consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder for fail-safe holding.
To replace this ISO 15552 cylinder accurately, match the 200 mm bore, 290 mm stroke, 75 mm adjustment range, PT G3/4 ports, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2—omitting FB, CA, CB, and CR. Because the 290 mm stroke is substantial, external guiding is highly recommended to prevent side-loading damage to the rod and front cap, despite the robust 40 mm rod diameter and M36x2 thread handling high bending loads.

- ✓ 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 SAIJ200AX290-75S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At its maximum rated pressure of 1.0 MPa, it delivers a peak push force of 3204 kgf.
The rear external stopper screw allows you to shorten the effective stroke by up to 75 mm from the 290 mm nominal length, creating a 215-290 mm usable travel window. This adjuster acts as a mechanical stop to set the end position and does not lock or hold the load without continuous air pressure.
