No matter the conveyor, its pulleys are often one of the most critical links to effective operation. If undersized, you risk the top cover of your conveyor belt separating from the bottom, rim and end disc failures or cracked hubs. While safer on the belt, an oversized pulley simply takes up too much space, often requires enhancements to other components and costs more than you need to spend. So to save your pockets and your belts, it’s important to size conveyor pulleys correctly. Designs for Every Application
About two years ago, pulley builder Superior Industries completed major product additions to help conveyor owners stuck between two pulley styles. In the wake of a production expansion, the company increased its range of conveyor pulleys, developing what many consider to be the widest range of on the market. Simpler than that, there’s not an aggregate-sized pulley Superior does not have access to in its collection.. To help you size a style for your application, the company helped Aggregates and Mining Today produce this chart:
