This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X400-100S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X400-100S in place of this model. 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 SIJ80 Dual Axis Adjustable Cylinder SIJ80X400-100S
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X400-100S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 400mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X400-100S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X400-100S
The AirTAC SIJ80X400-100S is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder. An external stop screw lets you trim the extend stroke by up to 100 mm on-site, giving a usable 300-400 mm extension out of the 400 mm nominal maximum. This 80 mm bore uses a G3/8 port, M20x1.5 rod thread, and 36 mm adjustable cushions, delivering 2513 N push and 2268 N pull at 0.5 MPa. The exact drop-in replacement is the SAIJ80X400-100S, matching the interface, bore, force, and mounting.
The SAIJ successor retains the ISO 15552 mounting dimensions for direct reuse of FA, LB, and TC brackets, and incorporates an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. Computed buyer insight: using the 0.5 MPa push figure yields a safe working load of roughly 1508 N (60% of 2513 N), translating to a 128 kg vertical lift with a 2:1 safety margin. The stop screw strictly sets the end position; it is not a load lock, so use an external rod lock or SAIL/BSAI variant for held loads.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X400-100S carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAIJ80X400-100S produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X400-100S Is Used
Variable Pitch Indexing
Allows on-site extend stroke adjustment up to 100 mm to alter part spacing without changing the cylinder.
Adjustable Diverter Gate
Tunes the extend position on-site to handle varying package widths on a single routing line.
Variable Depth Pusher
Trims the extend stroke from 400 mm down to 300 mm to push loads into different pallet depths.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X400-100S with the SAIJ80X400-100S
To replace the discontinued SIJ80X400-100S, order the drop-in SAIJ80X400-100S, ensuring your FA, LB, or TC mounting hardware and G3/8 porting transfer directly. Size both ways by checking neighboring bores: the 63 mm offers 2182 N push at 0.7 MPa, while the 100 mm provides 5497 N at 0.7 MPa. Select the -100 mm adjust window if your process requires field-tuning the extend stroke between 300 and 400 mm. Keep the -S suffix to retain the piston magnet for CS1-B/DS1-B switches (the SAIJ uses current AirTAC switches). For the 400 mm stroke, verify external guides to prevent rod bending and manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X400-100S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X400-100S FAQ
Yes, the SIJ80X400-100S is discontinued. The exact drop-in replacement is the SAIJ80X400-100S, which shares the same ISO 15552 interface, 80 mm bore, 400 mm stroke, 100 mm adjust window, G3/8 port, and mounting options.
The 80 mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and 4523 N at 0.9 MPa, with a 513 kgf max at 1.0 MPa. The external stop screw provides a 100 mm adjust window, allowing the extend stroke to be shortened from the 400 mm nominal maximum down to 300 mm on-site.
