ENDURO 719022RS Angular Contact Rubber Sealed Ball Bearing 15x28x7mm

Enduro Angular Contact Rubber Sealed Deep Groove Ball Bearings: These are special angular contact type bearings recommended to be used only with a hub or component designed for their usage. It is important to fit them in pairs and the correct way around, the seals on each side are different colours and the inner races are different diameters on either side, the larger diameter inner race is always the side to be under load, the smaller diameter should face each other in most installations. There should be a spacer tube between the bearings to preset any pre-load on the bearings, if there is no spacer it is important not to overtightened the bearings together as this will damage them.
Seals: Seals can be easily removed for applications that only require 1 seal.
Benefits: Prevents moisture and dirt getting into the bearing, lubricated for life, maximum load capacity
