The Split-Steel Pulley addresses the many problems that have plagued traditional pulleys for years. They are stronger than stamped/riveted pulleys, balanced, lighter weight to reduce drive wear, and feature multiple hub designs to make adjustments and removal and reinstallation simple. Split-steel pulleys provide for increased strength, reliability and reduced wear on drive systems. Split steel pulleys are cost-effective, lighter in weight and offer more design versatility than cast iron. They are also stronger than stamped pulleys. As split-steel pulleys are made from a single piece of steel, no balance holes are required, unlike a cast pulley where they must be balanced and drilled. These drill points for balancing can create weak points. The reduced weight (less rotational inertia) of the pulleys makes it easier for blades and other drive components to rotate up to speed. They also allow the electric clutch brake to stop the cutter blades faster with less wear on the clutch rotor and armature.
In short, the split-steel pulley design adds to the life of drive components, product reliability, and reduces maintenance time and cost.
We produce four different types of split steel pulleys:
