What is the difference between hub-cone type rear hubs?

Asked by: Jeanne Ganguli

What are hub cones?

The cups are built into the shell of the hub; the cones are conical nuts that screw onto the axle. Steel balls roll between these two parts. The combination of cup, cone and balls forms the bearing; there is a bearing on each side of the hub.

What is a cup and cone hub?

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. Modern freehubs tend to be more complex.

What is cup and cone bearing?

A bearing system which consists of a cup contains balls adjusted by a cone nut. This system features high durability and good maintainability. The key element of maintenance is to keep smooth rotation yet without a play.

How do you adjust hub cones?

Quote from video: Then very lightly tighten down the cone until you feel it contact the ball bearings. Tighten. Down the lock nut by hand onto the cone.

Why do Shimano 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 does cone bearing mean?

Definitions of cone-bearing. adjective. of or relating to or part of trees or shrubs bearing cones and evergreen leaves. synonyms: coniferous evergreen. (of plants and shrubs) bearing foliage throughout the year.

How does a cup and cone hub differ from a cartridge bearing hub?

The principal advantage of a cup-and-cone hub bearing system when compared to a cartridge system is that it is serviceable. When a cartridge bearing has worn out, it must be thrown away and replaced. This, however, is a simple process and so not altogether a bad thing.

How tight should cone nuts be?

Usually snug it and then wrench it maybe a quarter turn, but you should be able to feel if it’s too tight or too loose. Too tight and you might feel the bearings running rough and too loose you will feel the driver shift.

How long do Sealed bike bearings last?

How long does a wheel bearing last? Wheel bearings have an average lifespan of 136,000 to 160,000 km (approximately 85,000 to 100,000 miles).

Which is better ball bearing or sealed bearing?

We use sealed so the bearings are protected from road debris and weather, so they spin cleaner and with less friction for longer. Sealed bearings perform as well or better than loose bearings, without the maintenance.

What makes a good bike hub?

Good-quality bearings, sealed and protected from dirt and water, are the key to long and healthy hubs. Older or less expensive hubs may use cup and cone bearings, which contain two rings of loose ball bearings that sit in ‘cups’ inside the hub body, and are secured in place by conical nuts known as ‘cones’.

How do you tighten rear wheel cones?

Quote from video: Screw the cone in or out to tighten or loosen the bearing on the freehub. Make small adjustments and check the bearing between. Each.

Does Shimano have sealed bearing hubs?

Shimano hubs are sealed hubs, just as cartridge type hubs are “sealed” in one way or another.

Are Shimano hubs sealed bearing?

I presume you mean loose vs cartridge bearings. They are both sealed. High grade shimano hubs are actually pretty well sealed.

What size bearings do Shimano hubs use?

Quote from video:

How do you tighten a hub bearing?

Quote from video: And then tighten the nut finger tight. We will now reinstall.

What is a bearing cup?

Tapered roller bearing cups, or bearing races, are the outer ring around which the bearing rides. Combine roller bearing cups with tapered roller bearing cones to create tapered roller bearings that allow you to carry maximum combinations of radial and thrust loads simultaneously.

What size are bicycle wheel bearings?

4.762 mm (3/16″) – front wheel hubs (2 times 10 balls – i.e. 10 balls at each side most often). 6.35 mm (1/4″) – rear wheel hubs (usually 2 times 9 balls) and cup and cone bottom brackets (2 times 11). 5.556 mm (7/32″) Campagnolo Record front hubs and some exotic hubs of other manufacturers (2 times 9 balls).

How do I know what bearings I need for my bike?

A cartridge bearing’s size is determined by its inside diameter (ID), outside diameter (OD) and width. The measurements take the form of ’15x24x5mm’ or similar. They often have a corresponding universal identifier, which in the case of the aforementioned bearing, would be 6802, for instance.

What size are rear hub bearings?

Conventional front wheel cup and cone bearings have 10x 3/16″ ball bearings per side, whereas the rear wheel has 9x 1/4″ ball bearings per side.
