Torque Transmission releases their newly redesigned Variable Speed Pulleys with standard bores ranging from 1/4" to 3/4" in both hex and round shaft designs. These pulleys combine the cost savings and strength of glass reinforced nylon and steel hubs with the wear resistance of steel-clad flanges. Designed for belt sizes from 1/4" V to 5/8" V and horsepowers ratings from 1/12 HP to 1.0 HP these pulleys are designed to offer an econnomical alternative for many applications that may not require the expense of AC/DC variable speed motors and drives.

Our precision VSPR series features close tolerances on round shafts, molded keyway and a variety of spring pressures ranging from 6 pounds to 82 pounds depending upon model.

Simple belt tensioning ajustments allows for speed changes from 2.25:1 up to 2.8:1.
