Design Highlights

Design highlights of right angle gearbox

High-precision, ground spiral bevel gear sets incorporate helical geometry for smooth, accurate and repeatable rotation. Gears exceed in DIN 5.

Gears are carburized to provide a consistent tooth hardness for superior wear resistance and durability.

Steel Housing This housing is designed for maximum rigidity and corrosion resistance and offers multiple precision-machined surfaces for ease of installation.

Input/Output Shafts Multiple input and output configurations are available to meet a wide variety of applications.

The precision right angle gearboxes incorporate Nyogel 792D synthetic grease and are lubricated for life. Food grade grease is available upon request.

Design flexibility offers a number of options including; single shaft left or right, through shaft, hollow shaft, adaptors to accommodate most metric and NEMA motors, and multiple planetary stages to achieve ratios up to 500:1.
