Cup And Cone Bearings Bike

A basic bearing system is seen below.

Cup and cone bearings bike.

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. There is an improvement on this technique as follows. The cones are conical nuts that screw onto the axle. Steel balls roll between these two parts.

Bicycle bearings commonly use bearing balls placed in a cone compressed with a cup cup and cone bearing. We are using a rear wheel but the procedure is the same for a front. The hubs of most bicycle wheels revolve around one of two types of bearing system. If there is looseness from bearing play the cone can be move closer to the cup.

I do a lot of old bikes and finding cones is always a big pain. There are some exceptions use your old cones for reference. The locknut is tightened against the cone to prevent the cone from moving. Instead of fixing the cone in a vise and then grinding on it with a stone which may not be done very evenly it is easier to make a fixed rounded grinding surface and then attach the cone to a rotary drill or dremel tool to machine it.

Modern freehubs tend to be more complex. Measure your axle thread size the cones outer diameter and overall length. A disposable cartridge bearing or a cup and cone system which can be serviced. The bits that keep your bike rolling.

The cup is normally a permanent press fit into the hub shell. The cups are built into the shell of the hub. Cup and cone bearings. Standard bicycle bearing ball sizes.

If you cannot find an exact fit cone from our hub cone charts you will need to measure your existing cone and axle to find an approximate fit. Find out how to service cup and cone hubs in our walkthrough video step 1. Angular contact bearings also allow easier maintenance adjustability and serviceability. If the cones are screwed on too far they exert pressure on the bearing balls.

There is a bearing on each side of the hub. Cup with curved walls holds the balls while the cone presses on top holding them in place. For bearing ball standards see. Loose ball bearings are the most traditional and require the use of bearings with a mated cup and cone.

The cone traps the ball bearing. The combination of cup cone and balls forms the bearing.
