Hi-Lo 30TBRX3/4 HIL30TBR3/4

Product Number: HIL30TBR3/4Product Type: SheaveManufacturer Part Number: 30TBRX3/4Weight: 1.8 lbsThe HIL30TBR3/4 Sheave is designed to deliver a simplified, economical, and trouble-free drive system. This sheave is particularly effective when used with standard V-belts, offering minimal belt misalignment while maintaining efficient performance. For optimal operation, 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 crafted from a lightweight, corrosion-resistant aluminum alloy, ensuring high wearability and compatibility between the belt and the face surface. For added durability, the model 86TBR features close-grain cast iron faces.Permanently Lubricated Moveable Face Bushings: The sheave incorporates high load-carrying bronze bushings, precisely fitted and impregnated with specially formulated oil. This design helps to eliminate fretting and corrosion problems, making it suitable for severe corrosion conditions where the pulley shaft may require treatment to resist specific environmental factors.Torque Sensing Design: The sheave's torque-sensing design automatically regulates belt tension according to load requirements, reducing bushing wear. The peripheral support of the cam followers enhances durability, and the design eliminates the need for torque-carrying keys.
