Overview
The WC Branham 4304-0800 right-angle gear drive delivers dependable torque transmission with a 1:1 gear ratio and parallel-shaft configuration. Designed for mechanical applications requiring 90-degree power transfer, this AAS model accommodates 1-1/4″ x 1-1/4″ bore shafts and integrates seamlessly into existing industrial systems. W.C. Branham manufactures all gearboxes in Wisconsin using precision helical gears and sealed ball-bearing assemblies.
Key Features
- Sealed, pre-lubricated design: All W.C. Branham gearboxes are shipped pre-lubricated and installation ready, eliminating field assembly steps.
- Helical gear construction: Each gearbox has two 45-degree helical gears that mesh at 90º to rotate power, providing smooth, efficient operation.
- Ball-bearing support: All-ball-bearing configuration in a leak-proof, sealed gear case allows for higher thrust and radial load capabilities, lower operating temperatures, no leakage, and longer service life.
- Bi-directional operation: Gears slide axially along keyed shafts for easy installation.
- 1:1 speed ratio for direct drive applications.
- Parallel-shaft arrangement ideal for space-constrained layouts.
