Airtac SAIJ80 Adjustable Cylinder SAIJ80X220-30S
The AirTAC Airtac SAIJ80 Adjustable Cylinder SAIJ80X220-30S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 220mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X220-30S
The AirTAC SAIJ80X220-30-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 190 to 220 mm, allowing you to dial back the 220 mm nominal stroke by up to 30 mm during commissioning. This bore size delivers a push force of 2513 N at 0.5 MPa, scaling up to 4523 N at 0.9 MPa, making it well-suited for medium-to-heavy manipulation tasks.
Equipped with a standard -S magnet, the barrel integrates sensor grooves on both sides for direct mounting of CMSE reed or DMSE solid-state switches. The extruded aluminum profile maintains the exact ISO 15552 mounting interface without relying on tie-rods. The rear adjustment screw functions purely as a mechanical stop to fine-tune the end position and does not lock the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X220-30S Is Used
Machine Changeover
Dial in the 190-220 mm end-position during product size transitions without swapping cylinders or adding external mechanical stops.
Assembly Pressing
Apply up to 4523 N of push force at 0.9 MPa for seating components, using the 30 mm adjuster to limit travel and prevent over-travel.
Sensor Integration
Utilize the integrated -S magnet with DMSE solid-state or CMSE reed switches in the dual sensor grooves for precise end-of-stroke signaling.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X220-30S the Right Cylinder?
Select this 80 mm bore when an application requires pushing 2513 N at 0.5 MPa, stepping up from a 63 mm bore that provides 1559 N. The adjustable 190-220 mm travel window is ideal for machinery requiring variable end-stops during product changeovers, avoiding the need to physically swap a fixed-stroke SAI cylinder. For replacements, match the 80 mm bore, 220 mm stroke, 30 mm adjustment, PT threaded G3/8 port, and the -S magnet requirement.
Because the nominal stroke is 220 mm, the 25 mm carbon steel rod and M20x1.5 thread provide robust resistance to side-loading, though an external guide is recommended for heavy loads. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR options. If the load must be held without live air, use a SAIL or BSAI cylinder instead, as the rear adjuster here is a stop, not a brake.
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 SAIJ80 Adjustable Cylinder SAIJ80X220-30S FAQ
At 0.5 MPa it provides 2513 N of push force and 2268 N of pull force. At 0.9 MPa, the push force increases to 4523 N.
The rear adjuster screw acts as a mechanical stop, letting you shorten the 220 mm nominal stroke anywhere down to 190 mm. It only sets the travel end and does not hold the load without live air.
