Product Analysis: Bonfiglioli F 10 2 H 25 P80 B5

The Bonfiglioli F 10 2 H 25 P80 B5 is a shaft-mounted helical gear unit from the F Series. This series is specifically designed for applications where the gearbox «hangs» on the driven shaft, such as in belt conveyors, screw feeders, and industrial mixers. The F Series is known for its space-saving side-by-side mounting capability and its robust resistance to environmental stressors.

Key Features and Configuration

The F 10 2 features a 2-stage helical gear arrangement that offers high efficiency and low maintenance. The H 25 designation specifies a 25mm hollow output shaft, while the P80 B5 flange ensures compatibility with standard IEC motors. The shaft-mounted design eliminates the need for expensive foundations and flexible couplings, reducing both the initial installation cost and the ongoing maintenance requirements.

Reliability in Harsh Environments

The F 10 2 is built to endure. The housing is designed to minimize dust and moisture ingress, and the high-quality gearing ensures that vibrations are kept to a minimum even under heavy loads. Its «slim» profile makes it perfect for parallel-shaft mounting where multiple drives are installed in close proximity. The unit is typically filled with long-life synthetic lubricant, reducing the need for oil changes in standard operating conditions.

Maintenance Insights

When installing the F 10 2, ensure the torque arm is properly tensioned to prevent excess stress on the machine bearings. The 25mm hollow shaft should be lubricated with an anti-seize compound during installation to facilitate easier removal during future maintenance cycles.
