About the Airtac B01-MI Dedicated Pneumatic Cylinder B01-MI25X125CA
Delivering 245.3 N of push force at 0.5 MPa, the AirTAC B01-MI25X125CA is a double-acting round-body mini cylinder built for rigorous automation tasks. The B01- prefix designates this as an application-dedicated, customer-specified variant of the standard MI25X125CA, meaning it is mechanically identical to the base model but grouped for specific industrial deployments. It features a 25 mm bore, a 125 mm stroke, and a 1/8" air port. The stainless-steel barrel and piston rod provide excellent resistance to mild corrosion, making it highly suitable for damp environments or washdown areas where painted steel or aluminium cylinders would degrade.
This model incorporates fixed TPU bumper pads that effectively decelerate the piston at both stroke ends, reducing end-of-travel impact without the complexity of adjustable cushioning. Because it lacks the -S suffix, this specific SKU cannot accept magnetic position switches; adding an -S magnet variant is required to utilize CMSG, DMSG, or EMSG sensors. For practical sizing, plan for a safe working load of roughly 147 N, which equates to lifting about 12.5 kg vertically with a 2:1 safety margin.

Where the Airtac B01-MI Dedicated Pneumatic Cylinder B01-MI25X125CA Is Used
Package Diverting
Actuates routing gates on packaging lines, using its 245 N push force to reliably pivot heavy cardboard cartons onto secondary chutes.
Clamp Actuation
Secures aluminum extrusions in CNC machining fixtures, providing stable 125 mm travel to position raw stock before cutting operations.
Pallet Stops
Controls raising and lowering stop mechanisms on roller conveyors, holding pallets in place for robotic palletizing with its CA clevis mount.
Is the Airtac B01-MI Dedicated Pneumatic Cylinder B01-MI25X125CA the Right Cylinder?
When sizing this 25 mm bore unit, consider the neighboring bores: the 20 mm version offers 157.0 N of push force at 0.5 MPa, while the larger 32 mm provides 402.2 N. The 245.3 N output of this cylinder sits perfectly in between, making it ideal for moderate-duty handling. The CA rear pivot cover allows for clevis mounting, accommodating angular movement during the stroke. Keep in mind that a plain double-acting cylinder like this will drift if air pressure is lost or the valve is centered; the TPU bumpers only soften the stroke end and do not function as a brake. For applications requiring the rod to hold position under load, an external rod lock or pilot-operated check valve is necessary. Additionally, the 125 mm stroke requires attention to side loading—ensure adequate guiding 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-MI25X125CA FAQ
This 25 mm bore cylinder features a 1/8" port and generates 245.3 N push / 206.1 N pull at 0.5 MPa, and 343.4 N push / 288.5 N pull at 0.7 MPa. The theoretical maximum force is 50 kgf at 1.0 MPa.
The B01- prefix marks this as an application-dedicated variant of the MI25X125CA, sharing all physical specs with the base model. Because this SKU lacks the -S suffix, it has no magnet and cannot accept CMSG, DMSG, or EMSG sensors; you must specify the -S variant for position sensing.
