Abstract
PURPOSE:To reduce frictional resistance, to suppress temperature rise and to prevent burning of crankshaft by forming a film having high lubrication and burning resistance onto at least the inside face of circumferential groove of an outer ring where opposite endfaces slide each other. CONSTITUTION:A chromium oxide film 10 having excellent lubrication and burning resistance is formed onto the inside face 9a of circumferential groove of an outer ring 5 where opposite endfaces 4a of a ceramic roller make slippery contact. A shallow groove is formed in the inside face 9a where basic coating of SiO2+Al2O3 is applied followed by coating of chromium oxide. Consequently, frictional resistance is reduced, temperature rise is suppressed and burning can be blocked for relatively long term.
