Purchase now: Bonfiglioli VF 27 P1 10 P56 B14 Gearbox
Purchase now: Atlantechdrives provides you the VF 27 P1 10 P56 B14, an incredibly agile and ultra-compact worm gear reducer engineered by the renowned power transmission specialists at Bonfiglioli. As the smallest physical frame size within the legendary VF Series, the VF 27 is the absolute industry standard for fractional horsepower and micro-automation power transmission. This specific unit features a highly responsive 10:1 reduction ratio, making it the perfect solution for fast-moving small conveyor belts, automated packaging mechanisms, and precision dosing pumps where physical space is virtually non-existent. Configured with a standard P1 output housing, it is built to accept a fractional IEC P56 electric motor via a compact B14 face-mount flange. The lightweight die-cast aluminum casing provides excellent thermal dissipation, allowing for seamless integration into robotic end-effectors or suspended mobile frames without adding unnecessary weight.
Technical Specifications of the VF 27 P1 10 P56 B14
Despite its microscopic footprint, the VF 27 utilizes a precision-machined steel worm shaft driving a high-quality bronze worm wheel. This time-tested metallurgical pairing guarantees smooth sliding friction and exceptional longevity for light-duty cycles.

Expert Tips: Total Dynamic Reversibility
Understanding the mechanical properties of your selected worm gear ratio is critical for machine safety and design, even in micro-automation. Expert Tip: Because the VF 27 features a fast 10:1 reduction ratio, the lead angle of the internal steel worm thread is incredibly steep. This geometry makes the gearbox highly efficient, but it also means the gearbox is completely dynamically reversible. This signifies that any load applied to the output shaft can easily «back-drive» the gearbox and spin the electric motor backward when the power is turned off. It acts with almost zero mechanical braking force. If your micro-application involves lifting or holding a suspended weight against gravity, you must never rely on a 10:1 worm gear to hold the load securely.
Installation Advice: B14 Flange and Lifetime Lubrication
The VF 27 is a factory-sealed, maintenance-free unit. It is pre-filled with the exact required amount of high-performance synthetic gear oil and is «lubricated for life.» It lacks breather or drain plugs, completely eliminating the need for periodic oil changes and allowing the unit to operate reliably in almost any physical orientation. When mounting your IEC P56 motor into the B14 face-mount flange, always apply a thin layer of premium anti-seize paste to the motor shaft. This prevents fretting corrosion from locking the micro-motor to the input quill over years of vibration.
Frequently Asked Questions (FAQs)
Q: What does the P1 output designation mean for the VF 27?
A: The P1 designation refers to Bonfiglioli’s standardized housing geometry. It means the gearbox housing features integral mounting feet and a standard hollow output shaft bore with a keyway for simple machine integration.
Q: Can I change the oil in this gearbox?
A: No. The VF 27 is a sealed-for-life aluminum gearbox. Opening the casing or attempting to add oil will destroy the factory seals and void the operational warranty.
