In general, a needle bearing is a rolling-element bearing that uses long, slender cylindrical rollers to carry radial loads within a compact space. On heavy equipment, needle bearings are commonly found in pivot points, linkages and rotating shafts where room is limited and loads are substantial.
Use part number 0081717 as the reference when searching the catalog. Before ordering, check the recorded serial number ranges, configuration qualifiers and parent assembly conditions for the machine in question, because the catalog associations shown here do not confirm compatibility for every configuration.
