Overview
The Browning 3HB1-SF10 is a straight bevel right-angle gear reducer engineered for industrial applications requiring 90° shaft orientation and compact installation. Rated for a nominal maximum input of 2 HP with a 1:1 ratio and straight bevel gearing, this unit provides efficient torque transmission without the footprint demands of parallel-shaft reducers. The 3HB1 series is designed for direct shaft-to-shaft coupling in applications ranging from automation machinery to material handling and light industrial equipment.
Key Features
- 1:1 Speed Ratio — Input and output rotate at the same speed; ideal for right-angle direction changes without speed modification
- Straight Bevel Gearing — Delivers direct-mounted, shaft-input and shaft-output configuration
- Compact 3HB1 Frame — Space-efficient design for equipment with tight mounting constraints
- 2 HP Rated — Handles nominal maximum input rating of 2 HP at 1750 RPM
- Triangular Bolt Pattern — Standard floor-mount footprint with 153 lbs maximum overhung load capacity
- Cast Iron Construction — Durable housing for industrial duty cycles
