Abstract

A track link rail surface and roller interface includes a first roller including a cylindrical configuration defining a radial direction, a longitudinal axis, a circumferential direction, and a plane containing the radial direction and the longitudinal axis. The first roller includes a first track link rail engaging surface including a first concave arcuate surface defining a first concave radius of curvature. The interface includes a first track link including a first track link rail surface including a first convex arcuate surface defining a first convex radius of curvature that is less or equal to the first concave radius of curvature.
