Pulleys, Blocks, and Key Stocks at Do it Best
Die-cast pulleys are used to make lifting and moving heavy objects easier and also in mechanical applications to transfer power from the engine to other machine components. Pulleys can change the direction of the force placed on an object or increase the amount of force applied. Do it Best carries single groove and cone pulleys. Single groove pulleys work by guiding a rope, cord, or belt that is attached to an object through the groove on the pulley. Cone pulleys have multiple grooves of decreasing diameter and are used in applications where speed adjustments are necessary.
A key stock is a steel rectangular or square bar that provides torque to drive rotation and prevents slipping. Do it Best carries key stock in 12-inch lengths that can be cut to size for various applications, such as the creation of machine keys in custom sizes.
Pillow block bearings provide a stable housing for a rotating shaft. Pillow block bearings are specifically used for light to medium load applications. They are used in machinery and ensure that the shaft rotates smoothly.
How to Choose the Right Pulleys, Blocks, and Shafts
Application Needs
Consider the speed and torque requirements of your machinery, as well as the load being moved, if applicable. Larger pulleys may reduce speed but increase torque, while smaller pulleys increase speed and reduce torque. Determine if your application requires easy maintenance access or permanent installation when choosing pillow blocks.
Material Considerations
Die-cast stainless steel pulleys offer strength and corrosion resistance while being lightweight. They are ideal for outdoor power equipment. Pillow blocks should be selected based on load capacity and operating environment.
Compatibility and Sizing
Pulleys, blocks, key stocks, and shafts are offered in various sizes to ensure the correct pulley size and fit for your application. Selecting the right size is essential for safety and performance.
