R&P Knowledge Hub
Idler hubs support trailer wheels on axles that do not use electric brakes. A pre-greased hub kit simplifies installation because the bearings are already installed and lubricated inside the hub.
Always verify wheel bolt pattern, axle capacity, bearing sizes, and seal dimensions before installing a replacement hub.
