This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B06-SAI40X150S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B06-SAI40X150S 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-SI40X150S
The AirTAC Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI40X150S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø40mm bore and 150mm stroke, G1/4 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B06-SAI40X150S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI40X150S
The AirTAC B06-SI40X150S is a discontinued double-acting ISO 15552 profile cylinder. The B06- prefix marks it as a battery-manufacturing dedicated variant, though mechanically it is identical to the base SI40X150S. It delivers 628 N push force at 0.5 MPa, features a 16 mm rod, G1/4 port, and a 150 mm stroke.
Because this SI model is end-of-life, AirTAC specifies the SAI40X150S as the true drop-in replacement. The SAI retains the exact ISO 15552 mounting dimensions, bore, and port, but upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure. For reference, a safe working load is roughly 377 N (60% of the 0.5 MPa push force), and it can vertically lift about 32 kg with a 2:1 margin.

Where the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI40X150S Is Used
Cell Stacking Press
Applies steady 628 N clamping force during lithium cell stacking and alignment processes in battery module assembly.
Tab Handling
Drives 150 mm strokes to sort and transfer battery tabs or interconnect foils between welding stations.
Pack Indexing
Indexes battery packs along roller conveyors, utilizing the 32 kg vertical lift capacity for smooth transitions.
Replacing the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI40X150S with the B06-SAI40X150S
To replace the B06-SI40X150S, order the SAI40X150S. Confirm the ISO 15552 mounting interface (LB, FA, TC, etc.), the G1/4 port, and the -S magnet for CS1-B/DS1-B switches (the SAI uses current AirTAC switches). The 40 mm bore yields 628 N push at 0.5 MPa; if sizing up, the 50 mm bore provides 982 N. Remember that a plain cylinder drifts on air loss—the cushion only decelerates. For battery line load-holding, use an external pilot check valve, or specify the SAIL or BSAI lock variant. At 150 mm stroke, rod bending is low, but always guide lateral loads.
Replacement checklist
- ✓ Same ISO 15552 interface → B06-SAI40X150S
- ✓ 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-SI40X150S FAQ
Yes, the B06-SI40X150S is discontinued. The exact drop-in replacement is the SAI40X150S. The B06- prefix simply denotes the battery-manufacturing dedicated variant of the SI40X150S, and the SAI replacement matches its ISO 15552 mounting interface, 40 mm bore, 150 mm stroke, and G1/4 port exactly.
The 40 mm bore uses a G1/4 air port. Force output is 628 N push and 528 N pull at 0.5 MPa, 879 N push at 0.7 MPa, 1130 N push at 0.9 MPa, with a theoretical max of 128 kgf at 1.0 MPa. It operates at 30-800 mm/s.
