This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X230-50TC — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X230-50TC 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 SIJ80X230-50TC
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X230-50TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 230mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X230-50TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X230-50TC
The AirTAC SIJ80X230-50TC 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 180-230 mm window from the 230 mm nominal maximum. This 80 mm bore uses a G3/8 port, a Ø25 mm rod with M20x1.5 thread, and 36 mm adjustable cushions. It delivers 2513 N push and 2268 N pull at 0.5 MPa, reaching 4523 N at 0.9 MPa.
The exact drop-in replacement is the SAIJ80X230-50TC, retaining the same ISO 15552 interface, TC mounting, and force. The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. For sizing, the 0.5 MPa safe working load is roughly 1508 N (60% of push), yielding a 128 kg vertical lift with a 2:1 margin. Note this SKU lacks a -S magnet and cannot take a switch; the stop sets end position but is not a load lock.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X230-50TC 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 SAIJ80X230-50TC 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 SIJ80X230-50TC Is Used
Press Fit Tuning
Allows on-site extend stroke adjustment up to 50 mm to set precise pressing depth for varying bearing sizes without swapping cylinders.
Variable Length Diverter
A TC-mounted diverter gate that can be re-pitched on the fly by trimming the extend stroke to accommodate different package lengths.
Adjustable End Stop
Provides a field-tunable hard stop for pallet positioning, allowing 180 to 230 mm extend lengths to adapt to changing pallet heights.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X230-50TC with the SAIJ80X230-50TC
To replace the discontinued SIJ80X230-50TC, specify SAIJ80X230-50TC directly—it is a drop-in match for the ISO 15552 dimensions, TC mount, and G3/8 port. 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; this 80 mm bore provides 2513 N push and 2268 N pull at 0.5 MPa. Choose the 50 mm adjust window if you need on-site extend trimming between 180 and 230 mm. Because this SKU lacks the -S magnet, it cannot accept a legacy CS1-B or DS1-B sensor; add external sensing if required. For strokes of 300 mm or longer, verify your side-load limits to prevent rod distortion. The external stop screw only sets the end position—it is not a lock; for held loads, use an external rod lock, a pilot-operated check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X230-50TC
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
