This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B06-SAI40X500 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B06-SAI40X500 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 B06-SI Battery Dedicated ISO Standard Cylinder B06-SI40X500
The AirTAC Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI40X500 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø40mm bore and 500mm stroke, G1/4 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B06-SAI40X500, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI40X500
The AirTAC B06-SI40X500 is a discontinued double-acting ISO 15552 profile cylinder. The B06- prefix marks it as a battery-manufacturing dedicated variant of the SI40X500, mechanically identical with 628 N push force at 0.5 MPa, a 16 mm rod, and a G1/4 port. AirTAC replaced this EOL unit with the SAI40X500 drop-in, which matches the bore, stroke, and ISO 15552 mounting interface.
The SAI upgrade uses two Y-shaped one-way piston seals for low start-up pressure and long life. For this bore, safe working load is roughly 377 N (60% of the 628 N push force) and vertical lift is about 32 kg with a 2:1 margin. Note this SKU lacks a magnet, so it cannot take a CS1-B/DS1-B sensor. For load holding, explore the SAIL lock or BSAI clamp-lock variants.

Specifications follow the official AirTAC SI datasheet (now discontinued). The B06-SAI40X500 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |

Where the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI40X500 Is Used
Battery Cell Stacking
Drives precision stacking mechanisms in cell assembly lines, providing consistent 628 N push force for electrode alignment.
Module Handling
Transfers battery modules along conveyors, utilizing the 500 mm stroke to index packs between welding and inspection stations.
Tab Welding Press
Applies clamping pressure for tab welding operations, where the 32 kg vertical lift capacity securely holds components during the process.
Replacing the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI40X500 with the B06-SAI40X500
To replace the B06-SI40X500, order the SAI40X500. Confirm the ISO 15552 mounting accessory (LB, FA, TC, etc.) and the G1/4 port. Because this SKU lacks the -S magnet, it cannot accept position sensors; if sensing is needed, order the SAI with an S suffix for CS1-B/DS1-B switches. At 0.5 MPa the 40 mm bore yields 628 N push and 528 N pull; if you need less force, the 32 mm bore gives 402 N push, or step up to the 50 mm bore for 982 N. With a 500 mm stroke, use external guides to prevent rod bending and side loads. A plain cylinder drifts on air loss; for held loads use the SAIL lock, BSAI clamp-lock, or an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → B06-SAI40X500
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI40X500 FAQ
Yes, the B06-SI40X500 (battery-manufacturing dedicated SI40X500) is discontinued. The exact drop-in replacement is the SAI40X500. It is dimensionally interchangeable per ISO 15552, keeping the same 40 mm bore, 500 mm stroke, 628 N force, G1/4 port, and mounting interface.
