Cup And Cone Bearings Bike

I do a lot of old bikes and finding cones is always a big pain.

Cup and cone bearings bike.

Standard bicycle bearing ball sizes. 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. The cones are conical nuts that screw onto the axle. A basic bearing system is seen below.

The combination of cup cone and balls forms the bearing. For the rear first remove the cassette from the. If the cones are screwed on too far they exert pressure on the bearing balls. The hubs of most bicycle wheels revolve around one of two types of bearing system.

Cup with curved walls holds the balls while the cone presses on top holding them in place. The cone traps the ball bearing. Steel balls roll between these two parts. 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.

Angular contact bearings also allow easier maintenance adjustability and serviceability. Bicycle bearings commonly use bearing balls placed in a cone compressed with a cup cup and cone bearing. 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. Thanks for your suggestion.

Cup and cone bearings. The bits that keep your bike rolling. If there is looseness from bearing play the cone can be move closer to the cup. Modern freehubs tend to be more complex.

The locknut is tightened against the cone to prevent the cone from moving. Loose ball bearings are the most traditional and require the use of bearings with a mated cup and cone. There is a bearing on each side of the hub. Measure your axle thread size the cones outer diameter and overall length.

Taiwanese cones fit 9mm 9 5mm and 10mm diameter axles. Find out how to service cup and cone hubs in our walkthrough video step 1. The cups are built into the shell of the hub. For bearing ball standards see.

We are using a rear wheel but the procedure is the same for a front. The cup is normally a permanent press fit into the hub shell.
