This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X100-50 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X100-50 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 SIJ80X100-50
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-50 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 100mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X100-50, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-50
The AirTAC SIJ80X100-50 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 50 mm on-site, giving a usable 50-100 mm window from the 100 mm nominal maximum. This 80 mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa, features a 25 mm rod, M20x1.5 thread, and a G3/8 port. The exact drop-in replacement is the SAIJ80X100-50, matching the interface, force, and adjustability.
The SAIJ successor retains ISO 15552 mounting reuse and adds an upgraded two Y-shaped one-way piston seal for low start-up pressure. Computed buyer insight: safe working load is roughly 1508 N (60% of the 2513 N push @0.5 MPa), equating to a 128 kg vertical lift with a 2:1 margin. Note this SKU lacks a -S magnet, so it cannot take a switch. The stop screw sets end position but is not a load lock; for held loads use an external rod lock or SAIL/BSAI variant.

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 SAIJ80X100-50 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 SIJ80X100-50 Is Used
Press Fit Tuning
Allows operators to dial in the exact 50-100 mm extend position for pressing bearings without swapping cylinders.
Variable Stop Positioning
Adjusts the extend endpoint on the fly to accommodate different package sizes on a G3/8 powered line.
End-of-Stroke Dampening
Uses the external stop screw to set a precise mechanical endpoint for 80 mm bore assembly tooling.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-50 with the SAIJ80X100-50
To replace the discontinued SIJ80X100-50, order the drop-in SAIJ80X100-50, keeping the identical 50 mm adjust window and 100 mm nominal stroke. When sizing both ways, the neighboring 63 mm bore yields 1559 N push @0.5 MPa, while the 100 mm bore yields 3927 N push @0.5 MPa. Choose the 50 mm adjust window if your field tuning requires trimming the extend stroke by up to 50 mm on-site. Mounting options include FA, LB, and TC brackets. Because this SKU lacks the -S magnet, it cannot accept a magnetic switch; if sensing is required, select a -S model. For stroke lengths of 300 mm or greater, carefully verify side-load limits to prevent excessive rod wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X100-50
- ✓ 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 SIJ80X100-50 FAQ
Yes, the SIJ80X100-50 is discontinued. The exact drop-in replacement is the SAIJ80X100-50, which shares the same ISO 15552 interface, 80 mm bore, 100 mm stroke, 50 mm adjust window, and G3/8 port. The SAIJ family also features an upgraded piston seal.
The 80 mm bore provides 2513 N push and 2268 N pull @0.5 MPa, 3518 N push @0.7 MPa, and 4523 N push @0.9 MPa. The external stop screw window is -50 mm, allowing you to trim the extend stroke by up to 50 mm on-site (usable 50-100 mm). The stop sets end position and is not a load lock.
