Cup And Cone Bearings Bike
There are some exceptions use your old cones for reference.
Cup and cone bearings bike. If the cones are screwed on too far they exert pressure on the bearing balls. Taiwanese cones fit 9mm 9 5mm and 10mm diameter axles. The cup is normally a permanent press fit into the hub shell. A basic bearing system is seen below.
The bits that keep your bike rolling. The cone traps the ball bearing. Steel balls roll between these two parts. 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.
Modern freehubs tend to be more complex. The cones are conical nuts that screw onto the axle. The locknut is tightened against the cone to prevent the cone from moving. There is an improvement on this technique as follows.
For the rear first remove the cassette from the. Standard bicycle bearing ball sizes. If there is looseness from bearing play the cone can be move closer to the cup. Thanks for your suggestion.
There is a bearing on each side of the hub. Angular contact bearings also allow easier maintenance adjustability and serviceability. The hubs of most bicycle wheels revolve around one of two types of bearing system. We are using a rear wheel but the procedure is the same for a front.
Measure your axle thread size the cones outer diameter and overall length. I do a lot of old bikes and finding cones is always a big pain. Find out how to service cup and cone hubs in our walkthrough video step 1. For bearing ball standards see.
A disposable cartridge bearing or a cup and cone system which can be serviced. The cups are built into the shell of the hub. 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. Bicycle bearings commonly use bearing balls placed in a cone compressed with a cup cup and cone bearing.
Cup with curved walls holds the balls while the cone presses on top holding them in place. 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.
