About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-100S
The AirTAC SAIJ200X500-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 400-500 mm usable travel window by allowing you to dial back the 500 mm nominal stroke by up to 100 mm during commissioning. Equipped with a 40 mm piston rod, it generates 15708 N of push force and 15080 N of pull force at 0.5 MPa, making it suited for heavy-duty positioning tasks.
This variant includes a -S magnet for CMSE and DMSE sensors and uses a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance. The extruded aluminum barrel features sensor grooves on both sides, and the PT tapered port threads match the G3/4 standard for this bore size. The rear adjuster functions strictly as a travel stop for end-position tuning, not as a lock.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-100S Is Used
Heavy Press Tuning
Dial in the exact 400-500 mm end-stop distance for large metal forming or press operations, ensuring precise contact without machine recalibration.
Product Changeover Stops
Adjust the retract position on the fly when switching between product sizes on a heavy-duty conveyor line, using the 100 mm trim window to adapt stops instantly.
Large Assembly Positioning
Position heavy automotive or industrial components during assembly, leveraging the 15708 N thrust and fine-tuning the stroke to match fixture variations.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-100S the Right Cylinder?
Choose this 200 mm bore cylinder when your application requires up to 15708 N of thrust at 0.5 MPa and variable end-stop positioning. The 100 mm adjustment range is ideal for product changeovers on large machinery, allowing you to fine-tune the retract distance without swapping the cylinder or adding external stops. If your process demands load-holding without live air pressure, this standard SAIJ adjuster will not suffice; you should instead select an AirTAC SAIL or BSAI series cylinder.
Because the 500 mm stroke is substantial, the 40 mm rod helps manage side loads, but an external guide is still recommended for unsupported loads to prevent premature wear. This SAIJ model is dimensionally interchangeable with ISO 15552 cylinders and supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2. It operates at 30-500 mm/s and includes a magnet for solid-state DMSE or reed CMSE switches.
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 SAIJ200AX500-100S FAQ
At 0.5 MPa, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. The operating speed ranges from 30-500 mm/s.
The rear adjuster acts as a mechanical stop that lets you shorten the 500 mm nominal stroke by up to 100 mm, creating a 400-500 mm travel window. It is a stop for fine-tuning end positions, not a lock for holding loads without air pressure.
