Purchase now: Bonfiglioli C 12 2 P 10 P80 B14 Helical Gearbox
Purchase now: Atlantechdrives provides you the C 12 2 P 10 P80 B14, a premium-grade, highly efficient inline coaxial helical gearmotor assembly engineered by the power transmission experts at Bonfiglioli. Belonging to the highly respected C Series, this gearbox is specifically designed for industrial applications where maximizing energy efficiency and minimizing operating temperatures are strictly required. Unlike traditional 90-degree worm gears that lose substantial electrical power to sliding friction and heat generation, the helical gear architecture of the C 12 transfers rotational power through precise rolling contact, delivering mechanical efficiencies often exceeding 96%. This specific model features a 2-stage reduction design, achieving a fast 10:1 ratio. Configured with a solid output shaft and a «P» foot-mounted housing, it is built to accept a robust IEC P80 electric motor via a compact B14 face-mount flange. This inline unit is the ultimate solution for continuous fluid pumps, industrial mixers, material handling conveyors, and heavy-duty agitators.
Technical Specifications of the C 12 2 P 10 P80 B14
The C Series utilizes a highly rigid, unibody housing that maintains absolute internal gear alignment even under severe radial and axial shock loads. The internal helical gears are case-hardened and precision-ground to ensure incredibly quiet, continuous 24/7 operation without significant wear.

Expert Installation Advice: Managing Overhung Radial Loads
Unlike hollow-shaft mounted gearboxes, inline helical gears with solid output shafts rely heavily on precision front-bearing load management. Expert Tip: Because the C 12 features a «P» configuration, you will likely connect it to your driven machine via a chain sprocket, a V-belt pulley, or a pinion gear attached directly to the solid output shaft. You must carefully calculate the Overhung Load (Radial Load) applied to this shaft. If your drive chain is tensioned too tightly, the massive radial force pulls sideways on the gearbox output shaft. Over time, this extreme stress will crush the front bearings and cause the internal helical gears to misalign and grind against each other. Always position your sprockets or pulleys as close to the gearbox housing face as physically possible to minimize the mechanical leverage effect.
Maintenance: B14 Flange Fretting Corrosion Prevention
This specific model utilizes a B14 motor input flange, which is a face-mount design that significantly reduces the overall footprint of the machine. When installing your IEC P80 motor into the gearbox, you are inserting a solid steel motor shaft into a steel input hub. During thousands of hours of continuous industrial vibration, a phenomenon known as «fretting corrosion» inevitably occurs. This chemical reaction creates a rust-like powder that essentially cold-welds the motor shaft to the gearbox bore, making future motor replacement impossible without a hydraulic press. To prevent this, thoroughly clean the motor shaft and apply a heavy coating of high-quality molybdenum disulfide (MoS2) assembly paste before sliding the motor into the input hub.
Frequently Asked Questions (FAQs)
Q: What does the «2» mean in the part number C 12 2?
A: The «2» indicates that this gearbox features 2 internal reduction stages (two sets of mating helical gears). This dual-stage architecture allows the gearbox to achieve the 10:1 ratio smoothly and efficiently while maintaining high torque capacity in a relatively compact physical length.
Q: Why choose an inline helical gearbox over a standard worm gearbox for a 10:1 ratio?
A: Helical gearboxes offer significantly higher energy efficiency, produce far less radiant heat, and do not suffer from the rapid sliding friction wear inherent to bronze worm gears. They are ideal for applications running continuously where electricity costs and long-term durability are critical.
