Cup And Cone Ball Bearings

The surfaces are cut typically by grinding.

Cup and cone ball bearings.

Round ball bearings roll on the curved surface of the cup and cone. Bearing surfaces are made from hardened steel. Cup cone bearing. If the cones are screwed on too far they exert pressure on the bearing balls.

Steel balls roll between these two parts. There is a bearing on each side of the hub. Angular contact bearings also allow easier maintenance adjustability and serviceability. The cones are conical nuts that screw onto the axle.

Angular contact bearings of the cup cone type offer greater strength than sealed cartridge industrial bearings due their ability to displace lateral and vertical loads more effectively for super smooth rotation and longer durability. The combination of cup cone and balls forms the bearing. Cup cone sets bearings lm11749 lm11710 cup cone tapered bearing set brand new dura roll tapered bearing cup and cone set.

Even the highest quality bearing surfaces will have slight grinding marks.
