This model is discontinued

AirTAC has phased out the MAL series. The drop-in replacement is B06-SAI40X25 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B06-SAI40X25 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-SI40X25

The AirTAC Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI40X25 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø40mm bore and 25mm stroke, G1/4 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B06-SAI40X25, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI40X25

The AirTAC B06-SI40X25 is a discontinued double-acting ISO 15552 profile cylinder. The B06- prefix marks it as a battery-manufacturing dedicated variant of the SI40X25, mechanically identical to the standard line. Delivering 628 N push force at 0.5 MPa through a 40 mm bore, it is succeeded by the SAI40X25 drop-in replacement, retaining the exact G1/4 port, M12x1.25 thread, and ISO 15552 mounting interface.

This SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. A computed buyer insight: safe working load is roughly 377 N (about 60% of the 628 N push force), yielding a 32 kg vertical lift capacity with a 2:1 margin. Note this non-magnet SKU cannot take a sensor; legacy SI -S versions used CS1-B/DS1-B switches.

Replacing the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI40X25 with the B06-SAI40X25

To replace the B06-SI40X25, order the SAI40X25 drop-in: it matches the ISO 15552 mounting interface, 40 mm bore, 25 mm stroke, and G1/4 port. Confirm your mounting accessory (LB, FA, TC) and thread option (PT, G, NPT). Because this SKU lacks an -S magnet, it cannot accept position sensors; if sensing is needed, select an SAI40X25S and use current AirTAC switches. For sizing, the 40 mm bore yields 628 N push at 0.5 MPa; step down to a 32 mm bore (402 N) for lighter loads or up to a 50 mm bore (982 N) for higher force. The 25 mm stroke is short, so side-load risks are minimal, but always guide the load. A plain cylinder drifts on air loss; for load holding, use an external pilot check valve or specify the SAIL or BSAI lock variant.

Replacement checklist

  • ✓ Same ISO 15552 interface → B06-SAI40X25
  • ✓ 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-SI40X25 FAQ

Yes, the B06-SI40X25 (battery-manufacturing dedicated SI40X25) is discontinued. The exact drop-in replacement is the SAI40X25. It is dimensionally interchangeable per ISO 15552, matching the 40 mm bore, 25 mm stroke, 628 N force, G1/4 port, and mounting interface.

The 40 mm bore operates at 30-800 mm/s on a G1/4 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. The safe working load is approximately 377 N.
