This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X700-75S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X700-75S 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 SIJ80X700-75S
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X700-75S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 700mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X700-75S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X700-75S
The AirTAC SIJ80X700-75S 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 75 mm on-site, yielding a usable 625-700 mm forward travel from the 700 mm nominal maximum. The 80 mm bore uses a G3/8 port, M20x1.5 rod thread, and 36 mm adjustable air cushions. It generates 2513 N push and 2268 N pull at 0.5 MPa, reaching 4523 N at 0.9 MPa.
Because this SIJ model is end-of-life, the exact drop-in replacement is the SAIJ80X700-75S, retaining the same ISO 15552 mounting interface, bore, and force. The SAIJ upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. For sizing, the safe working load is roughly 1508 N (60% of the 0.5 MPa push), equating to a 128 kg vertical lift with a 2:1 margin. Note the stop screw sets end position only; it is not a lock. For load holding without live air, use an external rod lock or the SAIL/BSAI variants.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X700-75S 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 SAIJ80X700-75S 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 SIJ80X700-75S Is Used
Variable Pitch Indexing
Allows on-site extend stroke tuning up to 75 mm to alter part pitch without swapping the entire actuator.
Adjustable Reject Pusher
Fine-tunes the extend end position on-site to push varying product widths off a line into different chutes.
Pallet Positioning Stop
Sets a precise external stop for pallets, trimming the forward stroke up to 75 mm to adapt to new pallet depths.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X700-75S with the SAIJ80X700-75S
To replace the discontinued SIJ80X700-75S, order the drop-in SAIJ80X700-75S, which preserves the G3/8 port, 700 mm maximum stroke, 75 mm adjust window, and ISO 15552 mounting. When sizing both ways, the neighboring 63 mm bore yields 2182 N push at 0.7 MPa, while the 100 mm bore yields 5497 N at 0.7 MPa; this 80 mm bore provides 3518 N at 0.7 MPa. Choose the 75 mm adjust window if your extend stroke needs field tuning between 625 and 700 mm. Reuse FA, LB, or TC mounts directly. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches (the SAIJ uses current AirTAC switches). For the 700 mm stroke, use external guides to prevent rod bending and side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X700-75S
- ✓ 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 SIJ80X700-75S FAQ
Yes, the SIJ80X700-75S is discontinued. The exact drop-in replacement is the SAIJ80X700-75S. It shares the identical ISO 15552 interface, 80 mm bore, 700 mm stroke, 75 mm adjust window, G3/8 port, and mounting, but adds an upgraded two Y-shaped one-way piston seal.
The 80 mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N at 0.7 MPa, and 4523 N at 0.9 MPa, with a theoretical max of 513 kgf at 1.0 MPa. The external stop screw provides a 75 mm adjust window, shortening the extend stroke on-site from 700 mm down to 625 mm. The stop sets end position only and is not a load lock.
