Of the present utility modelly further be set to: described Elastic buckle is at least three.

By adopting technique scheme, Elastic buckle be skillfully at least three, make Elastic buckle can be more by retaining ring is fixed in mounting pipe, and can there is not the phenomenons such as retaining ring one end is subjected to displacement, even comes off, guaranteed the steadiness of installing.

Of the present utility modelly further be set to: on described retaining ring, be circumferentially distributed with oil hole.

By adopting technique scheme, on retaining ring, be provided with multiple oil holes, can add oiling agent or lubricant oil by oil hole, make to there is better lubrication effect between ball, the noise having produced when having extended the working life of bearing and having reduced bearing operation.

The utlity model has following advantage: the retaining ring easy accessibility on bearing makes to place or to adjust ball, avoid ball that wearing and tearing occur when mounted and cause reducing working life, can well fix retaining ring by the Elastic buckle in mounting pipe simultaneously, also easy disassembly and maintenance of while, bearing long service life.
