Purchase now: Bonfiglioli C 22 2 P 40 P80 B5 Helical Gearbox
Purchase now: Atlantechdrives provides you the C 22 2 P 40 P80 B5, a premium-grade, highly efficient inline coaxial helical gearmotor assembly engineered by the power transmission experts at Bonfiglioli. Belonging to the renowned C Series, this gearbox is designed for severe-duty industrial applications where energy efficiency and low operating temperatures are strictly required. Unlike traditional 90-degree worm gears that lose substantial power to sliding friction, the helical gear architecture of the C 22 delivers mechanical efficiencies often exceeding 96%. This specific model features a 2-stage reduction design, achieving a substantial 40:1 ratio that provides excellent torque multiplication. Configured with a solid output shaft and a «P» foot-mounted cast-iron housing, it is built to accept a robust IEC P80 electric motor via a standard B5 large mounting flange. This inline unit is the ultimate solution for heavy-duty material handling, continuous fluid pumps, industrial mixers, and long linear conveyors.
Technical Specifications of the C 22 2 P 40 P80 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. The internal helical gears are case-hardened and precision-ground to ensure incredibly quiet, continuous 24/7 operation.

Expert Installation Advice: Managing Overhung Radial Loads
Unlike 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» configuration, you will likely connect it to your driven machine via a chain sprocket, a V-belt pulley, or a pinion gear attached 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. 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 as physically possible to minimize the mechanical leverage effect.
Maintenance: B5 Flange Fretting Corrosion Prevention
When installing your IEC P80 motor into the B5 input flange of the C 22 gearbox, you are inserting a solid steel motor shaft into a steel input hub. During thousands of hours of continuous industrial vibration, «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 physically impossible without a hydraulic press. To prevent this, you must 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 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 40:1 ratio incredibly smoothly while maintaining high torque capacity in a relatively compact length.
Q: Why choose an inline helical gearbox over a standard worm gearbox?
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 mechanical durability are critical.
