About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX80-10S
The AirTAC SAIJ200X80-10-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 15708 N push force at 0.5 MPa and allows you to dial back the nominal 80 mm travel by up to 10 mm, creating a precise 70-80 mm usable end-position window for commissioning without external stops.
This variant features a SUS420J2 stainless steel rod, PT tapered ports, and a built-in magnet for CMSE reed and DMSE electronic sensors. It uses an extruded aluminum barrel with sensor grooves on both sides and omits the FB, CA, CB, and CR mounts, utilizing a reduced SAIJ set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX80-10S Is Used
Stroke Commissioning
Fine-tune the 70-80 mm retract window during machine setup to perfect end positions without adding external mechanical stops.
Product Changeover
Adjust the travel end on the fly to accommodate slight size variations in heavy-duty production lines.
Force Testing
Leverage the 15708 N push force at 0.5 MPa for heavy material testing, dialing back the stroke to prevent over-travel.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX80-10S the Right Cylinder?
Choose this 200 mm bore when you need maximum thrust, such as stepping up from a 160 mm bore that yields 10053 N push at 0.5 MPa. The adjustable stroke is ideal for fine-tuning retract end positions during product changeovers, whereas a fixed SAI cylinder locks you into one exact dimension. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for fail-safe holding, consider SAIL or BSAI types. The 40 mm rod and M36x2 thread handle high side loads, but an external guide is recommended for long unsupported travel.
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 SAIJ200AX80-10S FAQ
It delivers a push force of 15708 N and a pull force of 15080 N at 0.5 MPa, scaling up to a maximum of 3204 kgf at 1.0 MPa.
The rear adjuster screw lets you shorten the nominal 80 mm stroke by up to 10 mm, providing a usable 70-80 mm travel window. It functions as a stop, not a lock, so the cylinder requires live air to maintain position.
