Blocks And Sheaves

Martin Sprocket 3V Series Hi-Cap Wedge Stock QD sheaves are used in belt-driven systems for efficient power transmission. These sheaves offer a one-piece solid construction for durability, a 3 groove system for accommodating three belts simultaneously and QD bushings to allow easy installation and removal. They are made of Class 30 grey iron, offering a maximum textile strength of 30000 psi for use in heavy applications. These units have a smooth surface finish to minimise belt slippage and are ideal for use with 3V cross-section belts to ensure reliable power transfer.

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.
