Purchase now: Bonfiglioli VF 30 P1 20 P63 B5 B3 Gearbox
Purchase now: Atlantechdrives provides you the VF 30 P1 20 P63 B5 B3, a highly versatile and ultra-compact worm gear reducer engineered by the global power transmission specialists at Bonfiglioli. As one of the most popular sizes within the globally recognized VF Series, this fractional gearbox is the absolute industry standard for 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 small conveyor belts, automated packaging mechanisms, precision rotary indexing tables, and light-duty material handling. Configured with a standard «P1» output housing, it provides integral mounting feet and a hollow output shaft for seamless machine integration. It is built to accept a standard IEC P63 electric motor via a large B5 mounting flange. The die-cast aluminum casing guarantees exceptional thermal dissipation, allowing for continuous operation while keeping the overall assembly extremely lightweight, minimizing structural strain on your robotic end-effectors or mobile factory machinery.
Technical Specifications of the VF 30 P1 20 P63 B5 B3
Despite its small footprint, the VF 30 utilizes a precision-machined steel worm shaft driving a centrifugally cast bronze worm wheel. This time-tested metallurgical pairing guarantees smooth sliding friction and exceptional longevity for light-to-medium duty cycles.

Expert Tips: Dynamic Reversibility of a 20:1 Ratio
Understanding the tribology and mechanical properties of your selected worm gear ratio is critical for machine safety. Expert Tip: Many engineers falsely assume that all worm gearboxes act as mechanical brakes. Because the VF 30 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 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 offers 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; you must install an external failsafe brake on the AC motor.
Installation Advice: B5 Flange and Factory Lubrication
The VF 30 is a factory-sealed, maintenance-free unit. It is pre-filled with the exact required volume of high-performance synthetic ISO VG 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. When mounting your IEC P63 motor into the B5 input flange, you must apply a premium anti-seize paste to the solid motor shaft. Without this paste, microscopic vibrations will cause fretting corrosion, essentially cold-welding the motor to the gearbox’s input quill and making future motor replacement impossible without causing severe damage.
Frequently Asked Questions (FAQs)
Q: What does the P1 output designation signify for the VF 30?
A: The P1 designation refers to Bonfiglioli’s standardized housing geometry. It means the aluminum casing is cast with integral mounting feet at the base and features a standard hollow output shaft bore with a keyway for simple, direct-drive machine integration.
Q: Will the aluminum casing get hot during continuous 24/7 operation?
A: Yes. Because worm gears rely on sliding friction, a portion of the mechanical energy is always converted into radiant heat. The aluminum casing is specifically designed with cooling fins to run warm or hot to the touch during continuous duty cycles.
