Audited Supplier Your conveyor system has a complex design that includes more than just gears and chains. Maintain a nearly perfect system with idler sprockets from Roller Chain. Our parts are different than the standard star-shaped sprockets found across industries. Test your system's strength with this ball bearing gear. Each sprocket comes with a sealed ball-bearing centerpiece that protects the permanent lubrication. Dust and grime don't have a chance at entering these chain idler sprockets. Never overlook the importance of your idler sprockets because they create longevity in an otherwise volatile setup. Vibrations and wear are quickly controlled. The tension that you demand from these ball chain sprockets will deliver too. Simply choose from our prefabricated stock. We're also pleased to customize your order. Let us know about a particular sprocket with bearing you need so we can create the parts for you. Roller Chain supports your industry with precision quality.
Our ball bearing idler sprockets for roller chain use high-quality and high-precision ball bearings with metal or rubber shields to keep contaminants out and bearing grease in.
