Are Ball Bearing Pulleys Always Better?

A well-designed pulley, such as the above mentioned 2-stage bearing system, will remain highly efficient across the full working load range. However, some ball bearing pulleys may produce great results at a low load, then rapidly lose efficiency as the load increases. Read the rest

Solid Bearing vs Ball Bearing Pulley Blocks

Load type is a major consideration that can determine which style pulley (also referred to as a block) to use in your pulley system. Static loads are stationary, applying a constant load to the same area of the bearing. Dynamic loads occur when the line is in motion causing the pulley wheel (also known as the sheave) to turn. The type of bearing in a pulley can determine which type of load it is best suited for. Read the rest
