Are all bike bearings the same size?
Bearing sizing There are a few common sizes. Headsets and pedals tend to be 5/32”. Front hubs tend to be 3/16”. Rear hubs and bottom brackets tend to be 1/4”.
What size are freehub bearings?
You will need 20 (10 per side) 3/16″ bearings for the front hub and 18 (9 per side) 1/4″ bearings for the rear. The freehub body comes off with a 10mm hex wrench like in this tutorial from Park Tools. The bottom bracket is not serviceable.
Are cup and cone bearings any good?
The principal advantage of a cup-and-cone hub bearing system when compared to a cartridge system is that it is serviceable. Because the bearings are free to move in any direction, they can do so regardless of the trajectory of the wheel.
Why do Shimano still use cup and cone?
One of the main reasons why Shimano continues to use cup and cone is the ability of the bearing to “displace axial and radial loads effectively”. Subsequently, there’s less stress on the bearing system when the bike moves from side to side.
What are cup and cone bearings?
A basic bearing system is seen below. The cup is normally a permanent press fit into the hub shell. The cone traps the ball bearing. The locknut is tightened against the cone to prevent the cone from moving. If there is looseness from bearing play, the cone can be move closer to the cup.
What are cartridge bearings?
In the bicycle industry, cartridge bearings refer to a bearing assembly that can be entirely removed. and replaced into the component such as a hub or bottom bracket. Traditionally, each bearing. assembly in a hub would consist of four separate components; a cup, a cone, a retainer and balls.
Can you replace cup and cone bearings?
If the cup is damaged, it typically cannot be replaced. A new hub would be required. Cones are typically available as replacement parts. If inspecting axle, roll axle on flat surface.
Which bearing has a cup and a cone?
They consist of the “cup” that acts as the bearing’s outer race, which is pressed into the hub shell and not replaceable, and the “cone” that serves as the inner race and threads onto the axle. The hub bearings, which are usually 1/4″ in rear hubs and 3/16″ in front hubs, spin between the cup and cone.

What is a bearing cup?
This tapered roller bearing cup is designed to help carry a maximum combination of radial and thrust loads simultaneously. Note: When replacing bearings, replace both cone and cup to ensure optimum performance and longer life.
