Purchase now: Bonfiglioli C 32 2 P 15 P100 B5 Helical Gearbox
Purchase now: Atlantechdrives provides you the C 32 2 P 15 P100 B5, a premium, high-efficiency inline helical gearmotor assembly from Bonfiglioli’s renowned C Series. While traditional worm gears are excellent for 90-degree applications, coaxial helical gears offer vastly superior mechanical efficiency—often exceeding 96%. This means nearly all of your electrical motor power is translated directly into turning torque rather than being lost as radiant heat. The heavy-duty C 32 size is engineered with a 2-stage reduction, achieving a highly versatile 15:1 ratio. Designed with a solid output shaft and a «P» foot-mounted cast-iron housing, it is ready to accept a robust IEC P100 electric motor via a standard B5 mounting flange. This inline gearbox is the absolute optimal power transmission solution for high-duty-cycle applications such as continuous fluid pumps, heavy-duty mixers, and long linear conveyors.
Technical Specifications of the C 32 2 P 15 P100 B5
The C series features a highly rigid, unibody cast-iron housing that keeps the internal gears perfectly aligned even under severe radial and axial shock loads. The helical gears are case-hardened and profile-ground to ensure incredibly quiet operation.

Expert Installation Advice: Overhung Radial Loads
Unlike 90-degree worm gears, multi-stage inline helical gears rely heavily on precision front bearing alignment. Expert Tip: Because the C 32 features a foot-mounted «P» configuration with a solid output shaft, it is typically connected to the driven machine via a chain sprocket, a v-belt pulley, or a pinion gear. 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 helical gears to misalign and grind against each other. Always position your sprockets as close to the gearbox housing as physically possible to minimize the leverage effect, and strictly adhere to the maximum overhung load ratings specified in the Bonfiglioli engineering manual.
Maintenance: Preventing Motor Shaft Seizure
When installing your IEC P100 motor into the B5 input flange of the C 32 gearbox, you are inserting a solid steel motor shaft into a steel input hub. During thousands of hours of continuous vibration, «fretting corrosion» inevitably occurs. This reaction creates a rust-like powder that essentially cold-welds the motor shaft to the gearbox bore, making future motor replacement physically impossible without a hydraulic press. To prevent this, thoroughly clean the motor shaft and apply a heavy coating of 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 32 2?
A: The «2» indicates that this gearbox has 2 internal reduction stages (two sets of mating helical gears). This dual-stage architecture allows it to achieve the 15:1 ratio smoothly while maintaining a high torque capacity in a compact length.
Q: Why choose an inline helical gearbox over a worm gearbox?
A: Helical gearboxes offer significantly higher energy efficiency, produce far less heat, and do not suffer from the sliding friction wear inherent to worm gears. They are ideal for applications running 24/7.
