ENDURO 79032RS-MAX Angular Contact Rubber Sealed Ball Bearing 17x30x7mm

Enduro Angular Contact MAX Type 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.

MAX Type bearings have no cage and a filling slot for the balls. MAX stands for Maximum Balls possible in the bearing which is achieved by using the filling slot to insert the balls, the balls are effectively next to each other.

They generally have a 35% more load capacity than caged bearings. MAX bearings do not spin as smoothly as the cage bearings and should in general be used for suspension pivots or problem areas where standard bearings wear out prematurely.

Static Load capacities are limits well before deformation of the bearing and are conservative.

Always install bearings by pressing on the outer race only into a housing with a fixture that is a close match to its diameter, never knock bearings into their housings with a hammer - premature bearing failure will occur from knocking bearings into housings. With max type bearings in application like suspension pivots try to position the filling slot at 90 degrees to the loading direction where practical.

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
