[0032] The ball cage 3 is provided with a plurality of ball cages 3, and the plurality of ball cages 3 are respectively arranged on the spherical surface of the bearing ball 2.
[0033] In the specific embodiment of the utility model, the bearing ball 2 is uniformly separated by the ball cage 3 to reduce friction and wear, ensure smooth rolling of the bearing ball 2 in the first ball track 201, improve the running efficiency and service life of the bearing, and ensure accurate centering between the bearing inner ring 1 and the outer ring, improve the stability and reliability of the overall equipment, and the ball cage 3 is not a whole but an individual, which can conveniently replace the damaged part alone, reduce maintenance cost and downtime, and improve maintenance efficiency.
[0034] Specifically, please refer to Figures 1-4 The first shock pad 4 is fixedly connected in the first ball track 201, and the circumferential surface of the first shock pad 4 is slidingly connected with a plurality of bearing balls 2.
[0035] In this embodiment: the first shock pad 4 provides a buffer effect between the bearing ball 2 and the first ball track 201, reduces vibration and impact, improves bearing operation stability, while ensuring smooth rolling of the bearing ball 2 in the first ball track 201, reducing friction and wear, prolonging the service life of the bearing.
