Amana Tool 47762 Steel Ball Bearing Guide 1-5/16 Overall D x 5/16 Inner D x 21/64 Height

Amana Tool uses only the finest industrial quality precision ball bearings available. Bearings are double steel-shielded for extra rigidity and to inhibit dust. A special high-performance, high temperature grease is used for maximum life.Bearings #47701-HP, 47706-HP and 47712-HP have Teflon Shields which provide a better seal and increased bearing life while routing materials that generate very fine dust particles (such as solid surface).Note: Solvents should not be used to clean ball bearings, as this will deteriorate the special grease. 'Frozen' bearings (ones that do not rotate freely), should be replaced immediately.
