WVRB Precision Planetary Gearbox

MANUFACTURER DOCUMENTATION

Overview

A helical planetary series with a double-supported output structure. Compare frame size and ratio together: a larger reduction ratio does not necessarily increase the catalog torque rating.

Selection checks for WVRB Precision Planetary Gearbox

Use these questions with the manufacturer’s current model sheet and your actual operating conditions.

• Select frame size and ratio in the same configuration row; increasing the ratio does not automatically raise its rated torque.
• The model table uses P2 backlash limits. The separate P0 precision claim applies only to specified sizes and cannot be used as the table's P2 value.
