This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X500-100S, 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 SIJ100 Double Rod Adjustable Cylinder SIJ100X500-100S
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X500-100S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 500mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X500-100S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X500-100S
The AirTAC SIJ100X500-100S is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, now discontinued and replaced by the SAIJ100X500-100S. Its external stop screw lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 400-500 mm extend window from the 500 mm nominal maximum. The stop sets end position only; it is not a load lock.
The SAIJ direct reuses your ISO 15552 mounting and adds an upgraded two-piece Y-shaped piston seal for lower start-up pressure. For 500 mm strokes, use external guides to prevent rod bending. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ100X500-100S carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X500-100S Is Used
Variable Press Tooling
Trimming the extend stroke by up to 100 mm on-site allows rapid adaptation of press tooling without machining a new cylinder.
Adjustable Diverter Arms
Fine-tuning the 400-500 mm extend window lets operators reposition conveyor diverter arms precisely for changing package sizes.
Dynamic End-Stop Positioning
The external stop screw provides a hard mechanical end position for pallet stops, adjustable within the 100 mm window.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X500-100S with the SAIJ100X500-100S
To replace the discontinued SIJ100X500-100S, order the direct replacement SAIJ100X500-100S; it matches the ISO 15552 interface, G1/2 port, and 3927 N @0.5 MPa force. Choose the 100 mm adjust window if your end-position tuning exceeds 75 mm. Mounting options include FA, LB, and TC brackets. The -S suffix includes a piston magnet for legacy CS1-B/DS1-B sensors. Because the 500 mm stroke exceeds 300 mm, add external guides to manage side loads and prevent rod bending. Remember, the stop screw sets end position but does not lock the load on air loss; for held loads use SAIL, BSAI, or an external rod lock.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X500-100S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
