The SKF 1643 hub cap provides exceptional protection and lubricant containment for heavy-duty commercial trailer axles. Because proper hub maintenance prevents costly axle damage, this OE-quality composite component seals out road contaminants reliably. Therefore, it protects your wheel bearings and keeps fleet trailers moving safely on the road.
Engineers specifically built this composite hubcap with an embedded aluminum ring to distribute clamping loads evenly and resist severe impacts. In addition, the molded pressure ridge drastically improves sealing efficiency against the mounting face. The proven center-fill vented plug design maintains proper internal pressure while keeping dirt out. Furthermore, the threaded side fill plug incorporates a high-grade O-ring for extra leak protection, along with an integrated magnet that continuously traps metallic particles suspended in the lubricant. This hub cap works seamlessly with all common axle oils and synthetic wheel-end lubricants.
This hubcap features a universal 6-hole mounting design with a 5.500″ bolt hole circle diameter and an overall height of 2.469″. Mechanics commonly install this unit on heavy-duty commercial trailer axle hubs requiring an oil lubrication setup. For a complete seal replacement, pair this unit with related gasket part number 180.10619.1. For easy inventory mapping, this part directly cross-references numbers SKF 1643, 1643-C30, and Automann 180.CR1643-C30.
