Our Steel Ball Bearing for Front Hubs are made with low contact seals, with little to no grease (unless noted) for free spinning. 

We recommend oiling bearings every race day with a bearing oil like Lubtek or TRI-FLO; do not use a penetrating oil like WD-40 for lubrication. 

Bearing Dimensions:

I.D. 3/4"

O.D. 1-5/8"

Measure your bearing, Wheel Hub, and Spindle Axle Before Ordering.
