RADIAL SEAL FOR A TRACK LINK JOINT

In some implementations, a bushing may include a cylindrical body having an at least partially annular configuration. The cylindrical body may define a radial axis and may include an inner circumferential surface, an outer circumferential surface, a first end, and a second end. The inner circumferential surface may be configured to rotatably receive an outer surface of a pin of a track link joint. The outer circumferential surface may be configured to be rotatably received within a first counterbore of a first track link of a track link joint. The bushing may include at least one groove extending radially around a radial axis into the outer circumferential surface. The at least one groove may be configured to receive a first seal of a track link joint. The first seal may form a first radial seal between the outer circumferential surface and a first inner surface of the first counterbore. 在一些实现方式中，一种衬套可以包括具有至少部分环形配置的圆柱形本体。圆柱形本体可以限定径向轴线并且可以包括内圆周表面、外圆周表面、第一端，以及第二端。内圆周表面可以被配置为可旋转地接收履带链节接头的销的外表面。外圆周表面可以被配置为可旋转地接收在
