This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B06-SAI50X50S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B06-SAI50X50S 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-SI50X50S
The AirTAC Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI50X50S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø50mm bore and 50mm stroke, G1/4 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B06-SAI50X50S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI50X50S
The AirTAC B06-SI50X50S is a discontinued double-acting ISO 15552 profile cylinder. The B06- prefix marks this as a battery-manufacturing dedicated variant of the SI50X50S, mechanically identical to the base model. It delivers 982 N push force at 0.5 MPa through a 50 mm bore and 50 mm stroke, operating at 30-800 mm/s with a G1/4 port.
Because the SI line is end-of-life, buyers should order the drop-in SAI50X50S. This current-production replacement shares the exact ISO 15552 mounting interface, bore, stroke, force, and port. The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. For battery line upgrades, the SAI family also adds SAIL (air-released lock), SAIF (built-in 4M valve), and BSAI (clamp-lock) variants the SI lacked. A safe working load is roughly 589 N (about 60% of the 982 N push force), yielding a vertical lift capacity of about 50 kg with a 2:1 margin.

Where the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI50X50S Is Used
Cell Stacking Press
Applies the 982 N push force at 0.5 MPa to align and press lithium-ion battery cells during module stacking, utilizing the 50 mm stroke for rapid cycling.
Module Transfer
Pushes battery modules onto assembly conveyors, where the 50 kg vertical lift capacity and ISO 15552 mounting ensure stable handling.
Tab Welding Clamp
Holds battery tabs firmly in position for laser welding, relying on the adjustable 30 mm air cushions to decelerate the 20 mm rod smoothly at stroke ends.
Replacing the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI50X50S with the B06-SAI50X50S
To replace the B06-SI50X50S, order the SAI50X50S. Confirm the ISO 15552 mounting interface, 50 mm bore, 50 mm stroke, G1/4 port (PT/G/NPT thread options), and the -S magnet for CS1-B/DS1-B legacy sensors (the SAI uses current AirTAC switches). Sizing both ways: a 40 mm bore yields 628 N push at 0.5 MPa, while a 63 mm bore yields 1559 N. A plain cylinder drifts on air loss since the cushion only decelerates; for battery cell stacking or handling, use the SAIL lock, BSAI clamp-lock, or an external pilot check valve to hold loads. Rod material options include carbon steel, SUS420J2 (A), or SUS304 (B); Viton H seals raise the temperature range to 0-150 C.
Replacement checklist
- ✓ Same ISO 15552 interface → B06-SAI50X50S
- ✓ 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-SI50X50S FAQ
Yes, the SI series is discontinued. The exact drop-in replacement is the SAI50X50S. It is dimensionally interchangeable per ISO 15552, keeping the same 50 mm bore, 50 mm stroke, 982 N force, G1/4 port, and mounting interface. The B06- prefix simply marks the battery-manufacturing dedicated variant, and the SAI replacement shares these exact physical specs.
The bore is 50 mm with a G1/4 air port, M16x1.5 rod thread, and 30 mm cushions. Force output is 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, 1767 N push at 0.9 MPa, and a theoretical max of 200 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa, with speeds of 30-800 mm/s.
