摘要： PROBLEM TO BE SOLVED: To solve problems that (1) enclosed grease in a bearing is discharged in an early stage to a bearing end part to prohibit secure lubrication life as less grease is left in the bearing, and that (2) a quantity of grease discharged and held at the bearing end part is likely to cause leak of grease, and cause heat generation at a seal lip as the grease presses the seal lip.
SOLUTION: This bearing with a sealing is provided with a pair of inner rings 2 each having a track 2a in the outer circumference, an outer ring 3 having a plurality of tracks 3a in the inner circumference, a retainer 5 to retain conical rollers 4 in each row at a prescribed interval in a circumferential direction, and sealing devices 10 installed on both end parts of the outer ring 3. The sealing device 10 is composed of a seal case 12 of metal installed on the outer ring 3, and a seal body 20 fixed to the seal case 12 and having a the lip 24 in sliding contact with the outer circumferential surface of a large flange 2b of the inner ring 2. By means of the sealing 10, grease discharged to the bearing end part as the bearing is rotated is guided into the bearing. Grease pushed to the bearing end part in accordance with rotation is thus supplied back into the bearing. Grease enclosed in the bearing is thus effectively utilized, thereby lubrication life can be elongated.
