Pull type clutch release bearing capable of injecting grease for lubricating

The invention relates to a pull type clutch release bearing capable of injecting grease for lubricating, which includes a release sleeve and a bearing outer ring, a ball and a bearing inner ring that are positioned on one side of the release sleeve, wherein a seal ring is arranged between the bearing outer ring and the bearing inner ring on the outer side of the ball; a support spring is arrangedbetween the bearing outer ring and the end surface of the release sleeve; a housing is fixed between the outer end surface of the bearing outer ring and the outer wall surface of the release sleeve; an annular groove is arranged on the inner side end surfaces of the bearing outer ring and the bearing inner ring; a convex ring in clearance fit with the annular groove is arranged on inner side end surface of the release sleeve; and a grease injecting hole communicated with the inside of the annular groove is formed in the release sleeve. By forming the grease injecting hole communicated with the interior of the release bearing in the release bearing, when the lubricating grease in the release bearing fails and flows away due to high temperature during the use of the release bearing, the lubricating grease can be timely replenished to the interior of the release bearing through the grease injecting hole, so as to retain the excellent lubricating performance of the bearing, and prolong the service life of the release bearing.
