The DODGE ST series V-belt pulley is designed for power transmission systems that rely on V-belts. It mounts on a shaft and accommodates one or more belts, transferring motion from a motor to driven equipment while maintaining the desired speed ratio and torque. These pulleys are commonly used in fans, pumps, compressors, conveyors, and other process machinery where dependable alignment and performance are essential.

Understanding the ST series part number helps identify the right pulley. The first digit indicates the number of grooves, the letters B and V specify the belt profile (classic V), the following number is the outside diameter in inches, and the Q suffix denotes the taper bushing type. For instance, 2B5V78Q1 corresponds to a two-groove pulley with a 5V profile, 7.8-inch outside diameter, and Q1 bushing.

These pulleys serve a wide range of industrial applications, including food processing, water treatment, mining, cement, and ventilation systems. They are also found in agricultural equipment such as milling machines and grain elevators. When replacing a worn pulley or building a new drive, the ST series offers a practical balance between performance and maintenance cost.

To select the correct pulley, consider the belt profile and number of belts, the pitch diameter required for the transmission ratio, and the taper bushing compatible with the shaft. During installation, ensure the bushing is clean and free of burrs, tighten screws evenly, and verify alignment with a straightedge or laser. Misalignment beyond 0.5° can accelerate wear on both belts and bearings.

DODGE ST series pulleys are interchangeable with other brands that use equivalent taper bushings, provided the profile, pitch diameter, number of grooves, and bushing type match. When requesting a quote, include the complete part number of the original pulley or the shaft and belt measurements.
