Purchase now: Bonfiglioli VF 44 P1 14 P71 B5 B3 Gearbox
Purchase now: Atlantechdrives provides you the VF 44 P1 14 P71 B5 B3, a compact, highly responsive worm gear reducer engineered by the global transmission specialists at Bonfiglioli. As a core component of the widely utilized VF Series, this gearbox is the absolute industry standard for reliable, space-saving 90-degree power transmission. This specific unit is configured with a relatively low 14:1 reduction ratio, making it an excellent high-speed solution for fast-paced conveyor belts, rapid indexing tables, and dynamic packaging automation. Featuring a standard P1 output configuration, it is ready to accept an IEC P71 electric motor via a standard B5 large mounting flange. The die-cast aluminum housing provides exceptional heat dissipation while ensuring the unit remains lightweight enough for integration into mobile machinery or suspended robotic frames without causing excessive structural strain.
Technical Specifications of the VF 44 P1 14 P71 B5 B3
The VF 44 size is engineered with a profile-ground steel worm shaft driving a centrifugally cast bronze worm wheel. This time-tested metallurgical pairing guarantees smooth sliding friction, high operational efficiency, and exceptional longevity under varying dynamic loads.

Expert Tips: Dynamic Reversibility and Back-Driving
Understanding the mechanical properties of your selected worm gear ratio is critical for machine safety and design. Expert Tip: Because this specific VF 44 gearbox features a low 14:1 reduction ratio, the lead angle of the internal steel worm thread is quite steep. This makes the gearbox highly efficient (minimizing energy loss), but it also means the gearbox is completely dynamically reversible. This signifies that the load can easily «back-drive» the gearbox when the electric motor is turned off. It will not act as a mechanical brake. If your application involves a vertical lift, an inclined conveyor, or holding a suspended weight against gravity, you must never rely on a 14:1 worm gear to hold the load. You must install an external failsafe electromechanical brake on your AC motor to ensure the machine remains locked in position when power is removed.
Maintenance and B5 Flange Integration
The VF 44 is a factory-sealed unit, pre-filled with high-performance synthetic gear oil. It is «lubricated for life,» meaning it lacks breather, drain, or fill plugs. This completely eliminates the need for periodic oil changes and prevents leaks, technically allowing the unit to operate in any physical orientation despite the cataloged B3 position. This specific model features a B5 motor input flange. When mounting your IEC P71 motor, you must apply a premium anti-seize paste (such as Molybdenum Disulfide) to the motor shaft before inserting it into the gearbox input quill. Without this paste, fretting corrosion will occur over time, essentially cold-welding the motor to the gearbox and making future maintenance or motor replacement physically impossible without destroying the equipment.
Frequently Asked Questions (FAQs)
Q: What does the P1 output designation mean?
A: The P1 designation refers to Bonfiglioli’s standardized housing geometry for this size. It means the gearbox housing features standard integral mounting feet and a hollow output shaft bore, allowing for simple integration onto a machine base or direct shaft mounting.
Q: Can I change the oil in the VF 44?
A: No. The VF 44 is a maintenance-free, sealed-for-life aluminum gearbox. It contains exactly the right amount of synthetic lubricant from the factory to last for the entire design life of the internal gears and bearings.
