Purchase now: Bonfiglioli VF 27 P1 20 P56 B14 Gearbox
Purchase now: Atlantechdrives provides you the VF 27 P1 20 P56 B14, an incredibly agile, ultra-compact fractional worm gear reducer masterfully engineered by the global power transmission experts at Bonfiglioli. As the absolute smallest physical frame size within the widely utilized VF Series, the VF 27 represents the ultimate industry standard for micro-automation and highly space-constrained, 90-degree power transmission applications. This specific unit features a highly responsive 20:1 reduction ratio, making it the perfect solution for fast-moving miniature conveyor belts, precise automated packaging mechanisms, micro-dosing pumps, and robotic end-effectors where physical space is virtually non-existent. Configured with a standard «P1» output housing, it provides integral mounting feet and a hollow output shaft for seamless, direct machine integration. It is strictly built to accept a fractional IEC P56 electric motor via a compact B14 face-mount flange. The ultra-lightweight die-cast aluminum casing provides excellent thermal dissipation, allowing for continuous operation without adding unnecessary mass to your automated frameworks.
Technical Specifications of the VF 27 P1 20 P56 B14
Despite its microscopic footprint, the VF 27 utilizes a precision-machined steel worm shaft driving a high-quality, centrifugally cast bronze worm wheel. This time-tested metallurgical pairing guarantees exceptionally smooth sliding friction and longevity for fractional light-duty cycles.

Expert Tips: Dynamic Reversibility in Micro-Automation
Understanding the mechanical properties of your selected worm gear ratio is critical for machine safety and design, even in micro-automation. Expert Tip: Many engineers falsely assume that all worm gearboxes act as mechanical brakes. Because the VF 27 features a relatively fast 20:1 reduction ratio, the lead angle of the internal steel worm thread is quite steep. This geometry makes the gearbox highly efficient, but it also means the gearbox is completely dynamically reversible. This signifies that any kinetic load applied to the output shaft can easily «back-drive» the gearbox and spin the micro 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 20:1 worm gear to hold the load securely; an external motor brake is required.
Installation Advice: B14 Flange and Lifetime Lubrication
The VF 27 is a factory-sealed, completely maintenance-free unit. It is pre-filled with the exact required volume of high-performance synthetic ISO VG gear oil and is strictly «lubricated for life.» It lacks breather, fill, or drain plugs, completely eliminating the need for periodic oil changes and allowing the micro-unit to operate reliably in almost any physical orientation. When mounting your fractional IEC P56 motor into the B14 face-mount flange, always apply a thin layer of premium anti-seize paste to the solid motor shaft. This prevents microscopic fretting corrosion from locking the micro-motor to the input quill over years of continuous factory 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 ultra-compact aluminum casing is cast with integral mounting feet at its base and features a standard hollow output shaft bore with a keyway for simple machine integration.
Q: Can I open this gearbox to change or top up the oil?
A: No. The VF 27 is a sealed-for-life aluminum micro-gearbox. Opening the casing or attempting to add oil will destroy the factory seals, cause immediate leaks, and void the operational warranty.
