The first locking block 5 and the second locking block 6 are both provided with limiting parts facing the direction of the pocket hole 2. The distance between the first locking block 5 and the second locking block 6 is less than the distance between two adjacent partition beams 4. The first locking block 5 and the second locking block 6 cooperate to limit the roller 3. By evenly arranging a plurality of pocket holes 2 on the cage body 1, and each pocket hole 2 is provided with a roller 3. Between two adjacent pocket holes 2, they are separated by a partition beam 4. At least one set of locking components is installed on each partition beam 4. These locking components are composed of a first locking block 5 and a second locking block 6, which are respectively installed on the partition beams 4 on the adjacent sides of the pocket hole 2, and are both provided with limiting parts facing the direction of the pocket hole 2. The distance between the first locking block 5 and the second locking block 6 is less than the distance between two adjacent partition beams 4. Such a layout enables the first locking block 5 and the second locking block 6 to effectively cooperate to limit the roller 3. This design not only improves the stability and safety of the cage body 1, but also enhances its control ability over the roller 3, ensuring the precise positioning and movement of the roller 3 in the pocket hole 2, thereby improving the reliability of the entire system and the convenience of operation; the limiting part includes a roller 7 arranged on the first locking block 5 / second locking block 6. The first locking block 5 / second locking block 6 is provided with a roller groove 8 corresponding to the direction of the pocket hole 2. The roller 7 is arranged to roll in the roller groove 8. The roller 7 can rollingly cooperate with the surface of the roller 3. By arranging rollers 7 on the first locking block 5 and the second locking block 6, these locking blocks are respectively provided with roller grooves 8 in the direction facing the pocket hole 2, and the rollers 7 roll in these grooves and form a rolling cooperation with the surface of the roller 3. Such a structure not only improves the operation flexibility of the locking component, but also enhances its durability and reliability, ensuring the stability and smoothness of the locking during long-term use. It is more convenient for the roller 3 to be installed at the position of the pocket hole 2, and the roller 7 has better contact with the arc surface of the roller 3 and is more adaptable; an elastic pad 9 is circumferentially arranged on the surface of the roller 7. By axially arranging the elastic pad 9 on the surface of the roller 7, it is convenient for the roller 3 to be installed in the pocket hole 2, and the elastic pad 9 is not easy to cause damage to the surface of the roller 3; there are two sets of locking components. The first locking blocks 5 and the second locking blocks 6 of the two sets of locking components are respectively evenly arranged along the length directions of the adjacent two partition beams 4 of the same pocket hole 2. The configuration mode of the locking components is two sets, and each set includes a first locking block 5 and a second locking block 6. These two sets of locking components are evenly arranged on the adjacent two partition beams 4 of the same pocket hole 2 and are arranged along the length direction of the partition beam 4.This structure not only ensures uniformity and symmetry, but also may improve the overall stability and safety, and is also convenient for installation and operation; several oil storage grooves 10 are arranged at the positions corresponding to the rollers 3 in the pocket holes 2. By arranging the oil storage grooves 10 in the pocket holes 2, the excess grease on the surface of the rollers 3 can enter the oil storage grooves 10 for storage when the rollers 3 are rolling. When the surface of the rollers 3 lacks grease, the grease in the oil storage grooves 10 can also be evenly attached to the surface of the rollers 3 through the rolling of the rollers 3, avoiding waste of excess grease and also improving the service life of the bearing. When implementing this solution, first place the cage at the designated position in the bearing, and place the rollers 3 corresponding to the pocket holes 2 on the cage. At this time, the surface of the rollers 3 can contact the first locking block 5 and the second locking block 6 on the cage. Those skilled in the art apply force to press the rollers 3 into the pocket holes 2. At this time, the rollers 3 are under pressure to press the elastic pads 9 on the surfaces of the rollers 7 on the first locking block 5 and the second locking block 6 to deform, so that the distance between the first locking block 5 and the second locking block 6 becomes larger. When the deformation of the elastic pad 9 is not sufficient to allow the rollers 3 to enter the pocket holes 2, the partition beam 4 of the cage can also undergo slight deformation to allow the rollers 3 to enter the pocket holes 2 under pressure. The rollers 7 can roll when the rollers 3 enter the pocket holes 2, facilitating the entry of the rollers 3 into the pocket holes 2 and reducing the friction between the surface of the rollers 3 and the first locking block 5 / second locking block 6. In this solution, oil storage grooves 10 are arranged in the pocket holes 2. There are four oil storage grooves 10, which are respectively arranged at the four bends of the square pocket holes 2 and corresponding to the rollers 3. The excess grease on the surface of the rollers 3 can stay in the oil storage grooves 10 when the rollers 3 are rolling.
