摘要： An object of the present invention is to prevent breakup of segments which constitute a split type retainer for a tapered roller bearing, when the tapered roller bearing is being mounted on target equipment, thereby improving operability in the mounting process.
A segment 27 for a tapered roller bearing is provided with a predetermined number of posts 31 between a small-diameter-side end fringe 28 which constitutes a small-diameter-side circumferential edge of a split type retainer 16 and a large-diameter-side end fringe 29 which constitutes a large-diameter-side circumferential edge thereof. Pockets 32 are formed between the posts 31. At least the large-diameter-side end fringe 29, out of the small-diameter-side end fringe 28 and the large-diameter-side end fringe 29, is provided with a large-diameter-side engagement piece 36. When the bearing is mounted, the large-diameter-side engagement piece 36 is engaged with the large-diameter engagement member 23 fitted and fixed onto the bearing's inner ring, whereby the segment 27 is prevented from breaking up.

摘要： It is desired to prevent generation of negative pressure in the bearing space and to prevent entry of foreign matter such as water into the bearing. A bearing is provided which includes an inner race (1), an outer race (3), rolling elements (5) disposed between raceways (2 and 4) of the inner and outer races and retained by a retainer (6), and seal assemblies (7) provided at the respective ends of the outer race (3). Each seal assembly (7) includes a seal case (9) fitted on one end of the outer race (3), and an oil seal (11) mounted in the seal case. A check valve (20) is mounted in the seal case (9) which allows only a flow of gas from outside the bearing into the bearing space. A filter (29) is mounted in a flow passage in the check valve which allows passage of gas and prevents passage of liquid and solids.
