Radial deep groove bearings that have 5/32" Grade 20 balls, the largest in the industry, resulting in a 12% increase in static load compared to standard 6806 bearings. Dirt is kept out by no less than two double lip seal systems from the outside elements. The bearing seals are dual lip, groove type seals rather than standard 2RS types that other manufacturers use; one lip to keep the dirt out and the other to keep the 90% grease fill inside.
Bearings are filled both sides with Mobil HP 222 synthetic grease for the best protection and long lasting set up. Another external seal with dual lips on both sides and made from the best Silicone material guards from water and dirt penetration.
