About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX80-50
The AirTAC SAIJ200X80-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 30-80 mm usable travel window from its 80 mm nominal stroke. Delivering 15708 N of push force at 0.5 MPa, it handles heavy loads using a robust 40 mm piston rod. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches.
This variant features a SUS420J2 stainless steel rod (code A) for improved corrosion resistance and uses PT tapered port threads with a G3/4 connection. The rear adjustment screw acts purely as a mechanical stop to fine-tune the retract end position during commissioning without adding external stops. It is not a locking device and cannot hold loads without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX80-50 Is Used
Heavy Press Tuning
Dial in the exact 30-80 mm retract distance on heavy press assemblies, allowing precise end-position tuning during product changeovers without swapping cylinders.
Large Mold Handling
Position large molds securely with 15708 N of push force at 0.5 MPa, relying on the SUS420J2 stainless rod for durability in demanding industrial environments.
Variable End Stops
Adjust the mechanical stopper at the rear to fine-tune the travel window on the fly, accommodating varying material thicknesses on the production line.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX80-50 the Right Cylinder?
Choose this 200 mm bore when the 160 mm bore (10053 N push at 0.5 MPa) is insufficient for your heaviest positioning tasks. An adjustable stroke is preferred over a fixed SAI cylinder when you need to dial in the exact end-of-stroke position during machine setup or product changeover. The massive 40 mm rod and M36x2 thread handle significant side loads, but because this cylinder operates within an 80 mm stroke, external guiding is less critical than on longer travels.
For load-holding without continuous air pressure, this cylinder is inadequate because the rear adjuster and air cushions only set travel ends, acting neither as a brake nor a lock. In such cases, select an SAIL air-released lock, a BSAI clamp-lock, or an external pilot-operated check valve. This model is dimensionally interchangeable per ISO 15552 using the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting set, omitting FB, CA, CB, and CR.
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 SAIJ200AX80-50 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 the maximum 1.0 MPa pressure, it delivers 3204 kgf.
The rear adjuster screw lets you shorten the 80 mm nominal stroke by up to 50 mm, creating a 30-80 mm usable travel window. It functions as a mechanical stop for end-position tuning, not as a lock.
