About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX220-30
The AirTAC SAIJ200X220-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 190 to 220 mm, allowing you to dial back the nominal 220 mm stroke by up to 30 mm during commissioning. Delivering 15708 N of push force at 0.5 MPa, this 200 mm bore actuator handles massive loads with precision.
This configuration uses a SUS420J2 stainless steel rod for enhanced corrosion resistance and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. The rear adjustment mechanism functions strictly as a travel stop to fine-tune end positions, not as a load-holding lock.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX220-30 Is Used
Heavy Assembly Presses
Dial in the exact 190-220 mm end-stop during setup to ensure massive 15708 N press forces are applied consistently without over-traveling the fixture.
Pallet Positioning Stops
Adjust the rear stopper by up to 30 mm on the fly to accommodate different pallet depths on a single transfer line without changing the cylinder.
Large Component Machining
Fine-tune the clamping travel window for oversized workpieces, using the SUS420J2 stainless rod to resist coolant corrosion in harsh environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX220-30 the Right Cylinder?
Choose this 200 mm bore actuator when your application requires extreme thrust, stepping up from the 160 mm bore which yields 10053 N at 0.5 MPa. The adjustable 190-220 mm window is ideal for product-size changeovers on a line, eliminating the need to physically swap cylinders or bolt on external stops. For load-holding without live air pressure, select a SAIL or BSAI series cylinder instead, as the SAIJ adjuster only halts travel. Since the 220 mm stroke is under the 300 mm threshold, external guide requirements are less critical, but the robust 40 mm rod and M36x2 thread handle high side-load stresses well.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 220 mm stroke, 30 mm adjustment, PT G3/4 port, and mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). This unit lacks the -S magnet option, so confirm if CMSE or DMSE sensors are needed for your control system.
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 SAIJ200AX220-30 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. It can reach up to 3204 kgf at its maximum 1.0 MPa pressure rating.
The rear adjuster acts as a mechanical stop, allowing you to shorten the effective travel from 220 mm down to a minimum of 190 mm. It fine-tunes the retract end-position during commissioning but does not lock or hold the load without continuous air pressure.
