Abstract
A method of monitoring wear of a slew bearing system includes steps of assembling a slew bearing system having a first bearing ring and a second bearing ring concentrically positioned relative to each other forming at least upper and lower raceways, a plurality of bearing rollers positioned in each raceway between the first bearing ring and the second bearing ring, and an index system having a first reference connected with the first bearing ring and positioned relative to a second reference on the second bearing ring to provide a measurable distance between the first reference and the second reference, where the measurable distance changes with wear of the slew bearing system; and monitoring a change in the measurable distance between the first reference and the second reference to monitor wear of the slew bearing system.
