Martin 5V Series Hi-Cap wedge stock sheaves are used in power transmission systems, such as belt-driven applications. They feature a solid, one-piece design for increased durability & strength, a 3-groove system to accommodate up to three belts running simultaneously and QD (quick detachable) bushings to allow easy installation & removal without disassembling the entire drive system. These sheaves are made of Class 30 grey iron with maximum tensile strength and speed of 30000 psi & 6500 fpm, respectively. They are suitable for use with 5V cross-section belts and are designed to handle high power loads & torque, unlike standard sheaves.
Blocks and Sheaves are designed to lift heavy loads when used with heavy-duty wire rope or aircraft cable. Available options include forged block fittings with zinc finish and are riveted to all-steel sheaves that can resist weather damage and offer prolonged durability. Choose from a wide variety of types, sizes, load capacity or dimensions.
