Browning 1VP50X3/4 Variable Pitch Sheave 4.75" OD 3/4" Bore Cast Iron

The Browning 1VP50X3/4 Variable Pitch Sheave that is used in power transmission of HVAC systems. Constructed from cast iron, this sheave can be used to control the effective diameter of the belt by shifting the two halves of the sheave. This adjustment capability allows speed variation in driven equipment while maintaining motor speed, which is useful in applications where the output speed is variable. Some of the benefits are increased productivity, less power usage and better control of the machines, the applications are in tractors, harvesters, irrigation systems, conveyor systems, and all other manufacturing equipment where speed control is required.
