Airtac B01-MFC Dedicated Cylinder B01-MFC25X250SCA
The AirTAC Airtac B01-MFC Dedicated Cylinder B01-MFC25X250SCA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø25mm bore and 250mm 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-MFC25X250SCA
Delivering 245.3 N of push force at 0.5 MPa, the AirTAC B01-MFC25X250SCA is a double-acting, JIS-standard round-body mini cylinder built for high-speed actuation. The leading "B01-" prefix marks this as an application-dedicated (customer-specified) variant of the base MFC25X250SCA, meaning it is mechanically identical to the standard model but grouped into a dedicated line for specific customer builds. It features a SUS304 stainless steel barrel with riveted aluminium covers, offering excellent mild corrosion and washdown resistance.
A defining feature of this series is the variable air cushion at both ends, which uses a needle valve to soak up end-of-stroke shock at high speeds, protecting the load and cutting noise. For the same 25 mm bore and 250 mm stroke, the riveted rolling-packed body is noticeably shorter than an ISO 6432 cylinder, saving valuable mounting length. Equipped with a 1/8" port and an M10x1.25 male rod thread, it includes a built-in piston magnet (-S) for CMSG, DMSG, or EMSG switches, and a CA rear pivot cover.

Where the Airtac B01-MFC Dedicated Cylinder B01-MFC25X250SCA Is Used
High-Speed Diverting
Ideal for rapidly pushing small to mid-weight packages on a conveyor at 30-800 mm/s, using the variable air cushion to silently stop the 250 mm stroke without jarring the mechanism.
Light Assembly Pressing
Provides a reliable 245.3 N pressing force for seating electronic components, where the adjustable end-cushioning protects delicate parts from impact damage.
Automated Carton Sealing
Handles the repetitive motion of folding or sealing flaps on packaging lines, benefiting from the SUS304 stainless barrel's resistance to washdown environments.
Is the Airtac B01-MFC Dedicated Cylinder B01-MFC25X250SCA the Right Cylinder?
When sizing this 25 mm bore, evaluate your force needs both ways: the smaller MFC20 provides 157 N of push force at 0.5 MPa, while the larger MFC32 yields 402.2 N. The B01-MFC25X250SCA sits comfortably in the middle, offering a computed safe working load of roughly 147 N (about 60% of its 245.3 N push force) and lifting approximately 12.5 kg vertically with a 2:1 safety margin. Choose this model when your cycle speed demands the adjustable air cushion to prevent harsh impacts.
Keep in mind the cushion only decelerates the piston near the stroke end; it does not function as a lock or brake. If your application must hold a load on air loss or when a valve is centered, you must add an external rod lock or a pilot-operated check valve to prevent drift. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion, and the included magnet allows seamless sensor integration.
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-MFC25X250SCA FAQ
This double-acting cylinder has a 25 mm bore, a 1/8" port, and an M10x1.25 male rod thread. It delivers 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push and 288.5 N pull at 0.7 MPa, with a theoretical maximum force of 50 kgf at 1.0 MPa. The maximum standard stroke for this bore is 500 mm.
The "B01-" prefix indicates an application-dedicated (customer-specified) variant of the MFC25X250SCA; mechanically, the bore, stroke, seals, and materials are identical to the base model. The cylinder features a variable air cushion and a CA pivot cover, but the cushion only decelerates the piston near the stroke end—it is not a brake. The piston will drift on air loss, so an external rod lock or pilot check valve is required for load holding.
