R&P Knowledge Hub

Oil seals prevent lubricant from escaping the hub while keeping contaminants away from the bearings.
Proper fitment depends on both spindle diameter and hub bore dimensions.
Common service issues include leakage caused by incorrect installation depth or worn spindle surfaces.
Seals should be replaced during bearing service to maintain proper lubrication control.
Confirm dimensions and axle rating before ordering.
