<p>A bearing device (1) includes: an outer ring (13) having an outer ring raceway groove (17) on its inner circumferential surface; an inner ring (14) having an inner ring raceway groove (18) on its outer circumferential surface; balls (15) arranged between the outer and inner ring raceway grooves (17, 18); a retainer (16) retaining the balls (15); and a liquid lubricant supply device (12) supplying oil content of grease (21) to the space between the inner circumferential surface of the outer ring (13) and the outer circumferential surface of the inner ring (14). The liquid lubricant supply device (12) includes a liquid lubricant passage (30) providing fluid communication between the inner circumferential surface of the outer ring (13) and the outer circumferential surface of the inner ring (14); and a vibrating device (24) contacting the grease (21) to vibrate the grease (21) to supply a liquid lubricant to the space between the inner circumferential surface of the outer ring (13) and the outer circumferential surface of the inner ring (14) via the liquid lubricant passage (30).</p> |
