This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X60-40, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAI replacement keeps the same ISO 15552 mounting interface, bore, stroke, output force and accessories, so it drops straight into existing fixtures. It is the current-production version of this cylinder with an upgraded piston seal.
Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X60-40
The AirTAC SIJ63 Double Rod Adjustable Cylinder SIJ63X60-40 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 60mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ63X60-40, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X60-40
The AirTAC SIJ63X60-40 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 63 mm bore and 60 mm maximum extend stroke. An external stop screw lets you trim the extend stroke by up to 40 mm on-site, yielding a usable 20-60 mm window. The stop sets the end position but is not a load lock; the piston drifts on air loss. This SKU has no -S magnet and cannot take a switch.
It is replaced direct by the SAIJ63X60-40 (same G3/8 port, M16x1.5 rod, 30 mm cushion, 0.15-1.0 MPa range, 30-800 mm/s speed). The SAIJ upgrades the piston seal to two Y-shaped one-way elements for low start-up pressure and long life.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |

Where the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X60-40 Is Used
Variable-depth pressing
Dial in the exact 20-60 mm pressing distance for bearings or pins on-site without swapping cylinders when the part tolerance varies.
Adjustable reject diverting
Tune the extend stroke on a line to push varying product widths off the belt, using the 40 mm trim window to match package dimensions.
Variable-position stopping
Set a precise mechanical stop for incoming pallets, adjusting the end position on the fly as pallet sizes change without reprogramming.
Replacing the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X60-40 with the SAIJ63X60-40
Replace the SIJ63X60-40 directly with the SAIJ63X60-40, keeping the existing ISO 15552 mounting (Basic, FA, LB, TC, FTC, TCM1, TCM2) and the G3/8 port. The 40 mm adjust window covers a 20-60 mm extend stroke; if you need more extend, choose a longer nominal stroke and trim down. Because this is a non-magnetised SKU, add a -S suffix on the SAIJ order if you need legacy CS1-B/DS1-B sensor accuracy. For stroke lengths >=300 mm, verify the rod-end side-load tolerance. For held loads, the stop screw is not a lock—use an external rod lock, a pilot-operated check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ63X60-40
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X60-40 FAQ
Yes, the SIJ63X60-40 is discontinued. The direct replacement is the SAIJ63X60-40, which shares the same ISO 15552 interface, 63 mm bore, 60 mm stroke, 40 mm adjust window, G3/8 port, and mounting options. The SAIJ family also uses an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life.
The external stop screw provides a 40 mm trim window, allowing the 60 mm nominal extend stroke to be shortened to as little as 20 mm on-site. The port is G3/8 and the speed range is 30-800 mm/s.
