The small single direction tapered roller thrust bearings are used almost exclusively for the kingpin bearing arrangement of commercial vehicles (fig 4). They have a full complement of rollers and are held together by a sheet steel cover (fig 5). Most of these bearings are fitted with rubbing seals of wear and oil-resistant nitrile (NBR) rubber (fig 6). They are lubricated for life with a multi-purpose grease and require no maintenance. There are several designs which differ only in the design of the housing washer and the cover (fig 7).
