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.
