IDLE ROLLERS Ralphs-Pugh idler rollers are available in Through Hole, Blind Hole and Grading and Inspection configurations. Tubing is available in standard or "Hi-Impact" formulation. The "Hi-Impact" material has UV stabilizers and additional impact modifiers. Tube diameters and wall thickness are available for virtually every type of application. All plastic bushings and endplugs are molded in our facility assuring the highest quality.
These bushings (standard and heavy duty) are molded in acetal plastic or our best material - Ultra (Acetal plastic with Teflon additives). UHMW bushings are also available in specific sizes or upon request. Larger diameter tubes utilize an economical ABS plastic endplug in conjunction with the acetal bushings.
All Ralphs-Pugh materials are FDA approved. Stainless steel bushing adapters and cap screws are also available to complete your roller requirements. We pride ourselves on manufacturing to very high standards using the finest materials. We can also manufacture custom rollers to your specifications.
