Purchase now: Bonfiglioli C 22 2 P 20 P90 B14 Helical Gearbox
Purchase now: Atlantechdrives provides you the C 22 2 P 20 P90 B14, a premium-grade, highly efficient inline coaxial helical gearmotor assembly meticulously engineered by the power transmission experts at Bonfiglioli. Belonging to the highly respected C Series, this heavy-duty gearbox is specifically designed for complex industrial applications where maximizing energy efficiency, optimizing power density, and minimizing operating temperatures are strict operational requirements. Unlike traditional 90-degree worm gears that lose substantial electrical power to sliding friction and heat generation, the advanced helical gear architecture of the C 22 transfers rotational torque through precise rolling contact, delivering extreme mechanical efficiencies often exceeding 96%. This specific model features a robust 2-stage reduction design, achieving a fast 20:1 ratio. Configured with a massive solid output shaft and a «P» foot-mounted cast-iron housing, it is built to accept a standard IEC P90 electric motor via a compact B14 face-mount flange. This inline unit is the ultimate solution for driving continuous fluid pumps, industrial mixers, long material handling conveyors, and heavy-duty agitators requiring continuous 24/7 reliability.
Technical Specifications of the C 22 2 P 20 P90 B14
The C Series utilizes a highly rigid, unibody cast-iron 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 operation without significant wear over decades of use.

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 22 features a «P» foot-mounted configuration, you will likely connect it to your driven machine via a chain sprocket, a heavy 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 heavy-duty 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 heavy-duty 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 significantly minimize the mechanical leverage effect.
Maintenance: Helical vs. Worm Gear Tribology
Many automation engineers wonder why they should select a C Series inline helical gearbox over a standard W Series worm gear for a 20:1 ratio. The answer is long-term energy consumption and thermal durability. Worm gears rely heavily on sliding friction, which acts as a heater, wasting electrical amperage. The C 22 transfers torque via the rolling contact of its precision helical teeth. This means it consumes less electrical amperage to perform the exact same mechanical work, runs drastically cooler to the touch, and eliminates the rapid bronze gear wear inherent to worm drives, resulting in a significantly longer operational lifespan.
Frequently Asked Questions (FAQs)
Q: What does the «2» mean in the part number C 22 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 20:1 ratio incredibly smoothly and highly efficiently while maintaining massive torque capacity in a compact physical length.
Q: What is the benefit of the B14 motor flange on the P90 input?
A: The B14 is a face-mount design where bolts thread directly into the motor face. This drastically reduces the outer radial footprint of the assembly compared to a massive B5 flange, making it perfect for extremely tight machine enclosures.
