Purchase now: Bonfiglioli C 32 2 P 10 P112 B5 Helical Gearbox
Purchase now: Atlantechdrives provides you the C 32 2 P 10 P112 B5, a premium-grade, highly efficient inline coaxial helical gearmotor assembly expertly engineered by the power transmission professionals at Bonfiglioli. Belonging to the highly respected C Series, this gearbox is specifically designed for heavy industrial applications where maximizing energy efficiency, power density, 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 advanced helical gear architecture of the C 32 transfers rotational power through precise rolling contact, delivering mechanical efficiencies often exceeding 96%. This specific heavy-duty model features a 2-stage reduction design, achieving a fast 10:1 ratio. Configured with a massive solid output shaft and a «P» foot-mounted cast-iron housing, its standout feature is its input interface: it is built to accept a massive IEC P112 electric motor via a large B5 face-mount flange. This inline unit is the ultimate solution for driving large continuous fluid pumps, heavy industrial mixers, massive material handling conveyors, and heavy-duty agitators requiring substantial horsepower.
Technical Specifications of the C 32 2 P 10 P112 B5
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 delivered by the large P112 motor. 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 Extreme Overhung Radial Loads
Unlike hollow-shaft mounted gearboxes, inline helical gears with solid output shafts rely heavily on precision front-bearing load management, especially when driven by a powerful P112 motor. Expert Tip: Because the C 32 features a «P» foot-mounted configuration, you will likely connect it to your driven machine via a massive chain sprocket, a heavy V-belt pulley, or a thick 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 catastrophically 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: Handling the Massive P112 B5 Flange
This specific model utilizes an input flange designed for an IEC 112 frame motor, which represents a significant jump in physical size and weight (typically a 28mm motor shaft and a 250mm flange diameter). When installing your heavy IEC P112 motor into the gearbox, you are inserting a large solid steel motor shaft into a steel input hub. During thousands of hours of continuous heavy-duty 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 massive hydraulic press. To prevent this, thoroughly clean the motor shaft and apply a heavy coating of high-quality molybdenum disulfide (MoS2) assembly paste before hoisting the motor into the input hub.
Frequently Asked Questions (FAQs)
Q: What does the «2» mean in the part number C 32 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 incredibly smoothly and highly efficiently while maintaining massive 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 driven by a 112 frame motor?
A: A 112 frame motor produces substantial horsepower. Pushing that much power through a worm gear generates massive amounts of wasted heat due to sliding friction. Helical gearboxes offer significantly higher energy efficiency, saving thousands in electricity costs, and do not suffer from the rapid bronze gear wear inherent to worm gears under heavy loads.
