This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X1000-75S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X1000-75S 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 SIJ80X1000-75S
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X1000-75S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 1000mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X1000-75S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X1000-75S
The AirTAC SIJ80X1000-75S is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder. The external stop screw lets you trim the extend stroke by up to 75 mm on-site, giving a usable 925-1000 mm window from the 1000 mm nominal maximum. This 80 mm bore uses a G3/8 port, M20x1.5 rod thread, and 36 mm adjustable cushions. It delivers 2513 N push and 2268 N pull at 0.5 MPa, reaching 4523 N push at 0.9 MPa. The exact drop-in replacement is the SAIJ80X1000-75S, matching the interface, bore, stroke, force, and mounting.
The SAIJ upgrade uses an upgraded two Y-shaped one-way piston seal for low start-up pressure and long life. For sizing, a safe working load is roughly 1508 N (60% of the 0.5 MPa push), yielding a 128 kg vertical lift with a 2:1 margin. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches. The stop screw sets end position but is NOT a load lock; use an external rod lock or SAIL/BSAI variant for held loads. At 1000 mm, mind side-load and rod-bending—use external guides.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X1000-75S 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 SAIJ80X1000-75S 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 SIJ80X1000-75S Is Used
Sorter Diverter Tuning
Field-tune the 75 mm extend window on a package diverter to accommodate varying box sizes without swapping the entire cylinder.
Adjustable Press Position
Set the precise end-of-stroke contact point for a light assembly press, allowing 925-1000 mm positioning flexibility on the factory floor.
Variable Height Stop
Act as an adjustable physical stop for palletized goods, trimming the extend stroke on-site to handle different pallet stack heights.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X1000-75S with the SAIJ80X1000-75S
To replace the discontinued SIJ80X1000-75S, order the exact drop-in SAIJ80X1000-75S (insert A after the leading S), retaining the 80 mm bore, 1000 mm max stroke, 75 mm adjust window, G3/8 port, and ISO 15552 mounting. When sizing both ways, the neighboring 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N. Choose the 75 mm adjust window if you need to fine-tune the extend end position on-site between 925 and 1000 mm. Mounting options include Basic, FA, LB, and TC. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches (the SAIJ uses current AirTAC switches). Because the 1000 mm stroke exceeds 300 mm, account for side-load and rod-bending by using external guides to prevent premature seal wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X1000-75S
- ✓ 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 SIJ80X1000-75S FAQ
Yes, the SIJ80X1000-75S is discontinued. The exact drop-in replacement is the SAIJ80X1000-75S. It shares the same ISO 15552 interface, 80 mm bore, 1000 mm stroke, 75 mm adjust window, G3/8 port, and mounting, but uses an upgraded piston seal.
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. The external stop screw window is 75 mm, allowing you to trim the extend stroke from 1000 mm down to 925 mm on-site. The stop sets end position and is not a load lock.
