Description
The Browning 1VL40X1/2 variable pitch sheave is a cast iron adjustable-pitch pulley designed for fractional horsepower belt drives commonly used in HVAC blowers, fans, and light industrial equipment. This single-groove VL-series sheave features a 3.75-inch outside diameter and a 1/2-inch finished bore with keyway, allowing installation directly onto compatible shafts. The adjustable pitch design allows technicians to fine-tune the effective pitch diameter to control fan or blower speed without changing pulleys. It is compatible with 3L, 4L, A, 5L, and B belt sections, making it a flexible solution for variable-speed belt drive systems.
