Introduction to the F Series: space-saving excellence

The Bonfiglioli F Series represents the pinnacle of design for parallel shaft gearmotors, commonly known as shaft-mounted gearboxes. Thanks to their flat and elongated shape, these gearboxes have been designed to be installed directly onto the driven shaft of the machine, minimizing lateral footprint.

Choosing the F Series means adopting a successful solution for all those industrial applications where there is no room for a protruding coaxial or right-angle gearbox. Its modularity allows for a configuration flexibility that perfectly adapts to modern construction requirements.

This series is the number 1 choice for designers seeking a reliable component, capable of ensuring extremely high efficiency thanks to the quality of the parallel shaft helical gears.

Valuable technical features of the F Series range

The technical value of the F Series lies in its robust construction and the precision of the internal mechanisms. The housing, designed using Finite Element Methods (FEM), ensures maximum structural rigidity while maintaining a limited weight.

The series offers a wide range of torques and reduction ratios, allowing you to always find the ideal combination for every specific power and speed requirement.

Here are the main technical features:

• Flat and Compact Design: Ideal for “space-saving” shaft-mounted installation.

• Parallel Shaft Helical Gears: Ground to ensure quiet operation, thermal efficiency, and durability.

• Output Modularity: Available with hollow shaft (with keyway or shrink disc) or solid shaft.

• Versatile Mounting: Prepared for torque arm, flange, or threaded holes on the housing.

Effectiveness in conveyor transmissions

The use of the F Series is extremely effective in the material handling sector and in transport systems. The ease with which it can be mounted directly onto the head of a conveyor belt eliminates the need for coupling joints and bulky support bases.

The F Series is also a successful choice due to its energy efficiency. Parallel shaft gearboxes offer very low friction losses, transforming almost all electrical energy into effective driving force.

Focusing on the F Series guarantees constant operational stability, reducing vibrations transmitted to the machine and prolonging the service life of bearings and seals.

Modular design for total integration

The design of the F Series follows Bonfiglioli’s modular philosophy. It can be easily coupled with standard IEC electric motors, compact motors, or servomotors, making it a versatile asset for industrial automation.

FP Trasmissioni offers support to configure the F Series with various options, such as backstop devices for inclined belts or special seals for humid or dusty environments.

Advantages of the F Series design include:

1. Minimal Lateral Footprint: Allows for installing multiple gearmotors side-by-side in narrow production lines.

2. High Reliability: Oversized internal components to handle sudden shock loads.

3. Ease of Installation: Shaft mounting simplifies the mechanical alignment between the gearbox and the load.

Ideal applications for the F Series

The F Series is considered the number 1 solution in numerous industrial sectors where functionality must be combined with space optimization.

Main applications include:

• Conveyor Belts and Transporters: Both light and heavy-duty, for direct and clean driving.

• Elevation Systems: Where the compactness of the drive unit is fundamental for safety.

• Packaging Machinery: In packaging lines where the space between rollers is limited.

• Agitators and Mixers: Thanks to the housing’s robustness in withstanding radial loads.

The adoption of this valuable technology allows for simplifying the overall machine design, reducing frame costs and improving accessibility for maintenance.

Technical support and 3D visual consultancy

As with all our lines, 3D model visualization of the F Series is available on the website. Please note that these images are provided for illustrative purposes only, to allow you to understand the shape and modularity of the shaft-mounted gearmotor.

For executive design and engineering dimensioning phases, 3D models should not be used as certified dimensional bases. Our technical office is at your complete disposal to provide official CAD drawings and verified dimensional data sheets.

The FP Trasmissioni team will support you in choosing the correct service factor and the most suitable output configuration (hollow or solid shaft). Choosing the F Series with our consultancy is the key to a successful transmission.
