GGB DU — Metal-Polymer Bearings
The GGB DU is a metal-polymer bearing available in standard sizes featuring very good dry operation, good lubricated operation, and fair greased operation. This component exhibits a coefficient of friction ranging from 0.02 to 0.25 and 0.02 to 0.12, while machinability requires consultation with an applications engineer and the product is not RoHS compliant. Submit the exact part number, quantity, and application requirements to receive a formal quotation.

Request a QuoteWhy no listed price?
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued GGB references — within one business day.
