Upgrade your machinery with Raydafon Group's Double Groove V-belt Pulley, crafted from durable materials for superior power transmission and reduced slippage. Ideal for industrial professionals and DIY enthusiasts, it enhances efficiency and reliability in various applications. Experience smoother operations and longer lifespan—choose premium quality that stands out.
Double groove v-belt pulleys (also commonly known as double groove sheaves) are manufactured for either two single v-belts or a double banded v-belt. Our pulleys alongside the belts are manufactured following ARPM standards. They offer premium features like dynamic balancing and phosphate coating, most of which are made with a Grade 35 cast iron. Our standard inventory on double-groove pulleys includes popular configurations like a fixed bore, Q.D. bushed, taper bushed, and variable pitch. These pulleys can be found in agricultural, industrial, and home use applications. However, all our pulleys are industrial-duty to ensure durability and extended longevity.
Fixed Bore Double Groove Pulleys
Fixed bore pulleys are already pre-bored to fit a machined shaft. These pulleys will include two set screws and a standard key-way to ensure secure running operation.2AK Series (A-Type V-Belts):

Double Groove V-Belt Pulley Features
Double Groove V-belt pulleys are excellent for distributing torque to many belts. They are available with a single or double groove for varying power transmission capacities. The double grooves ensure proper torque distribution across the v-belts and provide mechanical redundancy.Double Groove V-belt pulleys are made from solid cast iron and are statically balanced. They are designed to work with "A" series belts. This allows them to increase the efficiency and life of your drive. They are also available with adjustable pitch.Double Groove V-belt pulleys have many features that make them the best option for your application. They are designed with thin cross sections that allow them to operate over smaller pulleys, which is advantageous for many applications. In addition, their design can accommodate larger ratios and shorter center distances, saving weight and space.Double Groove V-belt pulleys are great for industrial applications because of their wear resistance. The V-shaped belt wedges tightly into the Groove, increasing friction and operating torque. The V-belts are also designed to prevent slipping. Wear groov
