The Sterling SMV30A075-W1A Speed-Trol mechanical variable speed reducer uses a cone gear drive with a ribbed belt and dual variable-pitch pulleys to deliver infinitely variable output speeds over a wide range, with speed variation up to 10:1. Designed for industrial drives that require adjustable speed, it can regulate output for mechanical loads driven by a compatible motor. The unit weighs approximately 380 lb and measures about 42 in long by 38 in wide by 24 in high, indicating a substantial, floor-mounted installation for robust industrial environments.
