Specific embodiment
The present invention will be further illustrated below in conjunction with specific embodiments.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please the appended claims limited range.
The embodiments of the present invention is related to a kind of track roller bearing, as shown in Figs. 1-2, including outer ring 1, steel ball 3
With inner ring 4, the steel ball 3 is arranged between inner ring 4 and outer ring 1 by retainer 6, between the inner ring 4 and outer ring 1
It is provided with dustproof cover 2 positioned at the two sides of steel ball 3, the lateral wall of the outer ring 1 has channel 5 around circumference, the ditch
The bottom of 5 cross section of road is horizontal plane 11, and the two sides side wall of 5 cross section of channel is inclined-plane 13, two inclined-planes 13 it
