About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX700-50S
The AirTAC SAIJ200X700-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical adjuster, allowing you to dial back the 700 mm nominal stroke by up to 50 mm for a usable travel window of 650-700 mm. As an extruded aluminum profile cylinder, it provides standard ISO 15552 mounting dimensions without relying on tie-rods. It delivers massive thrust, generating 15708 N of push force and 15080 N of pull force at 0.5 MPa.
This specific configuration features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and includes a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors. The G3/4 PT tapered ports and 50 mm cushion strokes effectively manage the kinetic energy of heavy loads moving within the 30-500 mm/s speed range.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX700-50S Is Used
Heavy Machinery Changeover
Dial in the 650-700 mm retract end-stop during production format changes on large presses, accommodating different part sizes without swapping cylinders.
Precision Positioning Stops
Fine-tune the final resting position of heavy platforms or lifts at commissioning, using the 50 mm adjustment window to perfect the mechanical alignment.
Large Material Handling
Actuate heavy diverter gates or lifting arms on conveyor lines, relying on the 15708 N push force and adjustable end-position to manage varying load profiles.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX700-50S the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when your application requires up to 15708 N push force at 0.5 MPa; stepping down to a 160 mm bore would reduce that output to 10053 N. The adjustable stroke is chosen over a fixed SAI cylinder when you need to fine-tune the retract end position during machine setup or product changeovers without adding external stops. To replace an ISO 15552 cylinder, match the 200 mm bore, 700 mm stroke, 50 mm adjustment, G3/4 PT ports, SUS420J2 rod, and the -S magnet.
Because the 700 mm stroke is substantial, the 40 mm rod diameter and M36x2 thread provide robust support, but an external guide is still recommended to prevent excessive side-loading on the piston. Remember that the rear adjuster acts only as a travel stop to set deceleration, not as a lock; this SAIJ model cannot hold a load without live air pressure, so a SAIL or BSAI lock cylinder is required for load-holding duties.
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 SAIJ200AX700-50S FAQ
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder generates a push force of 15708 N and a pull force of 15080 N. At the maximum pressure of 1.0 MPa, it can deliver up to 3204 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the 700 mm nominal stroke by up to 50 mm, providing an effective travel window of 650 to 700 mm. It sets the end position and deceleration point, but it is not a lock and cannot hold the load without continuous air pressure.
