About the Airtac B01-MI Dedicated Pneumatic Cylinder B01-MI25X350SU
Delivering 245.3 N of push force at 0.5 MPa, the AirTAC B01-MI25X350SU is a double-acting round-body mini cylinder built for demanding application cycles. The B01- prefix designates this as an application-dedicated, customer-specified variant of the standard MI25X350SU, retaining the exact same mechanical specifications while grouping specialized builds into a dedicated line. It features a 25 mm bore, a 350 mm stroke, and a 1/8" air port.
The stainless-steel barrel and piston rod naturally resist mild corrosion, making it highly suitable for damp or washdown environments where painted alternatives fail. Integrated fixed TPU bumper pads absorb end-of-stroke impact to protect the mechanism. Because the push force at 0.5 MPa is 245.3 N, you can plan for a safe working load of roughly 147 N, which translates to lifting about 12.5 kg vertically with a 2:1 safety margin.

Where the Airtac B01-MI Dedicated Pneumatic Cylinder B01-MI25X350SU Is Used
Package Diverting Gate
Actuates a routing flap on a logistics sorting line, using the 245.3 N thrust to push parcels smoothly into secondary chutes.
Vertical Parts Lift
Raises lightweight industrial fixtures weighing up to 12.5 kg between processing tiers, relying on the 350 mm stroke for extended reach.
Lab Sample Ejection
Ejects processed testing trays from a damp analytical workstation, benefiting from the stainless steel construction and fixed TPU bumpers.
Is the Airtac B01-MI Dedicated Pneumatic Cylinder B01-MI25X350SU the Right Cylinder?
When sizing this 25 mm bore unit, consider the adjacent options in the range: step down to a 20 mm bore for 157.0 N push at 0.5 MPa, or step up to a 32 mm bore for 402.2 N if your application demands greater thrust. This SKU includes the -S magnet, allowing direct mounting of CMSG, DMSG, or EMSG electronic or reed switches for position sensing. The U-type back cover provides a 90-degree port and mounting orientation for tight spatial constraints.
Keep in mind that a standard double-acting cylinder drifts if air pressure drops or the control valve is centered; the internal bumpers only decelerate the piston near the stroke ends and do not function as a locking brake. To suspend a vertical load safely during an air loss event, incorporate an external pilot-operated check valve or a dedicated rod lock. Additionally, the 350 mm stroke requires careful alignment to prevent rod bending and premature seal wear.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check Use correct back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac B01-MI Dedicated Pneumatic Cylinder B01-MI25X350SU FAQ
This 25 mm bore cylinder uses a 1/8" air port. It generates 245.3 N push and 206.1 N pull at 0.5 MPa, increasing to 343.4 N push and 288.5 N pull at 0.7 MPa. The theoretical maximum force is 50 kgf at 1.0 MPa.
The B01- prefix indicates an application-dedicated, customer-specified variant of the base MI25X350SU, mechanically identical to the standard model. Because this SKU includes the -S piston magnet, you can directly mount CMSG, DMSG, or EMSG switches for position detection. It also utilizes the ISO 6432 mounting interface for standard mini-cylinder brackets.
