The seal fits the hub(outside) and the spindle(inside). Stock seal should work fine. Keeping the grease in the hub and bearing. The type of bearing won't matter much unless it is too tall in the hub. Use your finger to feel the bearing sets all the way down to the step. If you can feel a gap, you need to seat it all the way to the seat. Compare the seal outer lip to a stock seal. They should be very close to the same height.
