2" RF85 Double Wide Bearing

06-119

RF85 is a treatment that embeds calcium into the molecules of the bearing metal surface. The result is 85% less friction for greater durability and extended life.
It is a treatment and not a coating as it becomes part of the metal and wears with the metal. It does not wear off like a coating.
It is better than ceramic because if grit gets in a ceramic bearing, the balls get trashed. RF85 holds up much better.

Very little grease is needed for these bearings. DAYLube™ NanoCeramic Racing Grease is highly recommended for this product as it does not fling off and is compatible with the treatment.
