Airtac B01-MFC Dedicated Cylinder B01-MFC25X125U
The AirTAC Airtac B01-MFC Dedicated Cylinder B01-MFC25X125U is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø25mm bore and 125mm stroke, 1/8" air ports and a SUS304 stainless-steel barrel for mildly corrosive environments. For the same bore and stroke it is shorter than an ISO 6432 cylinder, saving mounting space.

About the Airtac B01-MFC Dedicated Cylinder B01-MFC25X125U
Designed to absorb high-speed end-of-stroke shock, the B01-MFC25X125U is a double-acting, JIS-standard round-body mini cylinder featuring a variable air cushion at both ends. The B01- prefix marks this as an application-dedicated variant of the MFC25X125U, meaning it is mechanically identical to the base model but grouped for specific customer builds. It delivers 245.3 N of push force at 0.5 MPa, yielding a safe working load of roughly 147 N or about 12.5 kg of vertical lift with a 2:1 margin. The riveted SUS304 stainless barrel and aluminium covers resist mild corrosion and washdown environments.
For the same 25 mm bore and 125 mm stroke, this cylinder is noticeably shorter than an ISO 6432 unit, saving valuable mounting length. It features a 1/8" port, an M10x1.25 male rod thread, and a U flat-end rear cover. Note that this specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG position switches.

Where the Airtac B01-MFC Dedicated Cylinder B01-MFC25X125U Is Used
High-Speed Diverting
Uses the 245.3 N push force to deflect packages on a conveyor, while the adjustable air cushion silently absorbs the 125 mm stroke end shock.
Carton Sealing Press
Ideal for compact assembly lines where the shorter-than-ISO-6432 body saves space and the U flat-end cover mounts flush to the frame.
Lab Washdown Station
The SUS304 stainless barrel withstands mild cleaning agents, pushing a 12.5 kg vertical fixture smoothly within the 30-800 mm/s range.
Is the Airtac B01-MFC Dedicated Cylinder B01-MFC25X125U the Right Cylinder?
When sizing this 25 mm bore, compare it both ways: step down to an MFC20 for lighter loads (157 N push at 0.5 MPa), or step up to an MFC32 when you need 402.2 N. The variable air cushion is essential if your cycle speed approaches the 800 mm/s limit or you are moving a heavy payload, as the needle valve lets you tune the deceleration to protect the load. This U-flat-end model does not hold position on air loss; the piston drifts, so add an external rod lock or pilot check valve for suspended loads. Because this SKU has no -S suffix, sensing is impossible without switching to a magnet-equipped variant.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/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/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac B01-MFC Dedicated Cylinder B01-MFC25X125U FAQ
This application-dedicated B01- variant matches the MFC25X125U mechanically. It has a 1/8" port and an M10x1.25 rod thread. At 0.5 MPa it pushes 245.3 N and pulls 206.1 N. At 0.7 MPa it pushes 343.4 N and pulls 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa.
No, this specific SKU lacks the -S magnet option, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. The variable air cushion at both ends only decelerates the piston near stroke end; it is not a brake and will not hold the load if air pressure drops.
