Webex standard idlers are perfect for many applications. But when your web requires special handling, look beyond the Webex standards. This is where custom machined surfaces and modifications can tailor a standard idler to provide a more custom fit to your specific application.

When determining which roll modifications are best, all options must be taken into consideration. For example, roll material, wall thickness, roll diameter, bearing type and shaft configuration all must work in conjunction with any surface treatment in order to maximize roll performance.

This is only an overview of some of the more commonly specified grooved metal finishes. When you’re ready to order, call us. Custom modifications are best determined with the help of the Webex customer support team. These professionals have years of experience in specifying machined roll surfaces to fit specific web handling applications. They’ll not only help you determine the right specifications, they’ll help protect your budget, too.
