The lower plane of circular body forms annular groove, the bottom surface of annular groove forms central axis along central through bore around uniform multiple the first greasing holes and the second greasing hole, and the first greasing hole to the distance of the central axis of central through bore is greater than the distance of the second greasing hole to the central axis of central through bore;
In the upper plane of described the first circular protrusions, form the second annular groove, the second circular protrusions is at the center of the second annular groove, and the upper end in the first greasing hole passes the bottom surface of the second annular groove and is connected with the second annular groove;
On the sidewall of described the second circular protrusions, form radial direction through hole, radial direction through hole is connected with the upper end in the second greasing hole corresponding with it.
The bottom surface of described annular groove forms central axis along central through bore around uniform 14 the first greasing holes and 14 the second greasing holes, on the sidewall of the second circular protrusions, form 14 radial direction through hole, radial direction through hole is corresponding one by one with the second greasing hole.
Described 14 the first greasing holes, 14 radial direction through hole are corresponding with the pocket hole homogeneous one on retainer.
The central axis of described circular body, the first circular protrusions, the second circular protrusions, annular groove and the second annular groove all coincides with the central axis of central through bore.
Outstanding effect of the present utility model is:
Compared with prior art, it can directly carry out fatten on the assembly of unilateral bearing (being made up of retainer, roller, spring), grease is added on the internal-and external diameter of assembly, while making assembly be mounted to bearing ring, ensure just can produce between roller and raceway one deck oil film, improve the life-span of bearing.
