Description
The Carrier KR51BJ413 is a steel material two-groove sheave. Sheaves are simply wheels that have grooved rims through which the direction of a belt or a rope can be changed. In HVAC equipment they are particularly used in belt driven systems to transfer power between a motor and a fan. The KR51BJ413 has two grooves that mean that it can take two belts at the same time, which can increase the amount of power that is being transferred, or it can be used to operate several parts with just one motor.
