摘要： The present disclosure provides an arc-shaped segment (1) for assembling a segmented bearing cage. An arc length L and a radian angle θ of the arc-shaped segment (1) satisfy the following relationship: 360L/πD−20°≤θ≤360L/πD+30° with D being a diameter of the segmented bearing cage. The arc length L refers to an arc length corresponding to the radian angle θ of the arc-shaped segment (1). The present disclosure also provides a segmented bearing cage comprising a plurality of arc-shaped segments (1) as mentioned herein. And the present disclosure provides a bearing comprising the segmented bearing cage. After being assembled in the bearing, a plurality of arc-shaped segments abut on or connect with each other, to form a complete cage. Relevant structures and dimensions of the arc-shaped segments can be designed according to the diameter of the interested bearing and the actual needs.

摘要： A bearing seal provides a first flinger and a second flinger. A first sealing body formed on the first flinger is configured to form sealing engagement with a corresponding surface of the second flinger and/or the second bearing ring, and a second sealing body formed on the second flinger is configured to form sealing engagement with a corresponding surface of the first flinger and/or the first bearing ring. The seal has a lean structure formed at least within a partial scope thereof that faces the rolling elements and/or the cage, which lean structure allows axial space to be released to the interior of the bearing, such that a ratio W/H of the axial size W within the partial scope of the seal to the spacing H between the first and second bearing ring shoulders falls within a range of W/H ≤ 0.5. The invention also provides a rolling bearing with standard boundary dimensions, with the bearing seal provided on its axial side.

摘要： The present disclosure provides a cage for bearings. The cage includes a pocket (2) for accommodating a rolling element of the bearing. The pocket (2) completely encloses the corresponding rolling element on a cylindrical surface where a pitch circle of the cage is located. The pocket has a roughly ellipsoidal shape. The ellipsoidal shape of each pocket (2) has a major axis L1 and a minor axis L2. The major axis L1 and the minor axis L2 satisfy the following relationship: L2

摘要： A bearing seal provides a first sealing member to be secured to a shoulder on one side of a first bearing ring and a second sealing member that can be secured to a shoulder on the same side of a second bearing ring. A labyrinth seal gap is formed between the first sealing member and the second sealing member, which has at least one tooth-shaped turn. On the basis of the above bearing seal, the present invention further provides a rolling bearing that employs the bearing seal on an axial side thereof.

摘要： A cage includes a first sub-part having a plurality of first partitions integrated as a whole and a plurality of first pocket portions formed by adjacent first partitions. A second sub-part has a plurality of second partitions integrated as a whole and a plurality of second pocket portions formed by adjacent second partitions. A first recess is provided on the first partition belonging to a first set of the plurality of first partitions. A second pin extends along an axial direction from the second partition belonging to a second set of the plurality of second partitions. The second pin is fixed in its corresponding first recess. The first set of first partitions includes any one or more of the plurality of first partitions. The second set of second partitions includes any one or more of the plurality of second partitions and correspond to the first set of first partitions respectively.
