This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B06-SAI32X25S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B06-SAI32X25S 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-SI32X25S
The AirTAC Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI32X25S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 25mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B06-SAI32X25S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI32X25S
The AirTAC B06-SI32X25S is a discontinued double-acting ISO 15552 profile cylinder. The B06- prefix marks it as a battery-manufacturing dedicated variant of the SI32X25S, mechanically identical to the base model. Delivering 402 N push at 0.5 MPa, it is replaced drop-in by the SAI32X25S.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. The G1/8 port and interface are unchanged. Safe working load is about 241 N, allowing a 20 kg vertical lift. The SAI family adds SAIL lock, SAIF valve and BSAI clamp-lock variants the SI lacked.

Specifications follow the official AirTAC SI datasheet (now discontinued). The B06-SAI32X25S carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The B06-SAI32X25S 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 B06-SI Battery Dedicated ISO Standard Cylinder B06-SI32X25S Is Used
Cell Stacking
Ideal for battery cell stacking and alignment tasks requiring a compact 25 mm stroke and precise low-force actuation.
Module Handling
Pushes or indexes battery modules along assembly conveyors where a 402 N push force at 0.5 MPa is sufficient.
Tabbing & Welding
Clamps battery tabs during ultrasonic welding or laser processing, benefiting from the adjustable air cushions.
Replacing the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI32X25S with the B06-SAI32X25S
To replace the B06-SI32X25S, order the SAI32X25S. It drops into existing ISO 15552 fixtures with the same 32 mm bore, 25 mm stroke, G1/8 port and M10x1.25 rod thread. Keep the -S magnet for CS1-B/DS1-B sensors (the SAI uses current AirTAC switches). For higher force, the neighbouring 40 mm bore offers 628 N push at 0.5 MPa. A plain cylinder drifts on air loss; for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. The 25 mm stroke is short, so side-load risks are minimal, but ensure alignment to avoid rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → B06-SAI32X25S
- ✓ 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-SI32X25S FAQ
Yes, the B06-SI32X25S is discontinued. The exact drop-in replacement is the SAI32X25S. It shares the same ISO 15552 mounting interface, 32 mm bore, 25 mm stroke, force, G1/8 port and mounting accessories. The B06- prefix simply denotes the battery-manufacturing dedicated variant, and the SAI32X25S matches it mechanically.
The 32 mm bore features a G1/8 air port and M10x1.25 rod thread. Force ratings are: push 402 N and pull 345 N at 0.5 MPa, push 563 N at 0.7 MPa, push 724 N at 0.9 MPa, and a theoretical max of 82 kgf at 1.0 MPa. Operating speed is 30-800 mm/s.
