Product Analysis: Bonfiglioli 300 Series Planetary Drive
The Bonfiglioli 130 1 10 STD 130A1 CD 28 S1 OR SB KL UH1 is a high-torque industrial planetary gear unit belonging to the 300 Series. These units are designed for the most demanding heavy-duty applications, where massive torque, high overhung load capacity, and extreme durability are required. The 300 Series is the choice for industries such as mining, construction, marine, and large-scale manufacturing.
Configuration Breakdown
This complex configuration designates a Size 130 unit with 1 reduction stage and a ratio of 10:1. The «STD» indicates a standard execution, while «CD 28» refers to the specific output shaft design (typically a cylindrical keyed shaft). The additional codes (S1, OR, SB, KL, UH1) specify auxiliary features such as high-temperature seals, reinforced bearings, or specific mounting orientations, ensuring the unit is perfectly tailored to harsh operating conditions.
Advanced Technical Features
- Series: 300 (Planetary Gear).
- Size: 130.
- Reduction Stages: 1.
- Gear Ratio: 10:1.

High-Performance Planetary Gearing
The planetary design provides superior torque density compared to helical or worm gearboxes. By distributing the load across multiple planet gears, the Size 130 unit can handle extreme peak loads and shocks. The 10:1 ratio is ideal for primary reduction stages in large mechanical transmissions, offering high mechanical efficiency (approx. 97% for a single stage).
