From its inception in 1869, David Round Company has established itself as a leading provider of high-quality chain sheaves and chain wheels for demanding applications. Typically center-bored with options for customization, these sheaves are designed to meet specific needs. Hand-wheel sheaves cater to low-load requirements such as roll-up doors and hard-to-reach valve actuation, while load wheel sheaves handle heavy loads like furnace doors, ladles, and process equipment. All DRC sheaves come standard with a blank hub for machining upon arrival or offer customization options including bores, keyways, and set screws. With capacities reaching up to 10,080 lbs., these precision-engineered products ensure perfect mating with DRC chain. Optional guides are available for hand-wheel sheaves. Additional sizes and capacities can be requested. Manufactured in the USA, David Round Chain is a requirement for valid sheave warranty. Shipping point FOB applies. Steel surcharges may be applicable. See the Related Items tab for David Round Chain Sheaves & Load Wheels Optional Chain Guide.
