Hi-Lo 40TBR X 1/2 HIL40TBR1/2

Product Number: HIL40TBR1/2Product Type: SheaveManufacturer Part Number: 40TBR X 1/2Weight: 2.1 lbsThe HIL40TBR1/2 Sheave is engineered to provide a simplified, economical, and trouble-free drive system. It is specifically designed to work efficiently with standard V-belts, ensuring minimal belt misalignment while delivering consistent performance. For optimal results, the drive should be aligned with the belt at the mean diameter of the variable pulley, and the recommended shaft center distance should be used as a minimum.Key Features:Aluminum Alloy Pulley Face Material: The pulley faces are made from a lightweight, corrosion-resistant aluminum alloy that ensures high wearability and compatibility with the belt surface. The model 86TBR features close-grain cast iron faces for enhanced durability.Permanently Lubricated Moveable Face Bushings: The sheave includes high load-carrying bronze bushings, precisely fitted and impregnated with specially formulated oil. This design minimizes fretting and corrosion problems, making it ideal for environments with severe corrosion conditions where the pulley shaft may require additional treatment to resist specific environmental factors.Torque Sensing Design: The sheave's torque-sensing design automatically adjusts belt tension according to load requirements, reducing bushing wear. The peripheral support of the cam followers further enhances reliability, and the design eliminates the need for torque-carrying keys.
