How is the load of the bike transferred to the hub cartridge bearings with a through axle?

6 min read

Asked by: Amy Evans

The thru axle only tightens the other axle to the fork. Load is mainly carried by the other axle. Then the 18mm inner diameter bearing gets the load via the other axle. However, some hubs (for example Novatec D201SB fatbike hub) use the thru axle itself to carry the load.

What is a through axle hub?

A thru-axle (TA) is a wheel attachment system that secures a wheel on a hub between a pair of dropouts on a bicycle frame or fork. The thru-axle threads directly through the fork/frame holes and into the wheel hub, which makes the wheel secure from detaching.

How do bike bearings work?


Quote from video: The ball bearings inside rotate round. And each race touches it in an opposing. Direction. And if you replace this with a bearing.

How does hub attached to axle?

Most axle hubs are attached to the axle through the use of bearings and an axle nut. The bearings, typically roller bearings, ride in a bearing race that is mounted within the hub, while the axle is positioned through the bearing and the hub.

How many bearings are in a bike hub?

Hub Assembly



Make sure balls are seated flat in cup. For rear hubs, the common number is 9 balls of 1/4-inch diameter per side. For front hubs, the common number is 10 balls of 3/16-inch diameter per side.

How do bike through axles work?

Thru-axles



In a thru-axle system, the dropouts have closed-off circular openings, rather than an open end. That means there’s no risk of the wheel falling out as you ride. The thru-axle passes through the dropout on one side of the wheel and screws into threads in the dropout on the other side.

Is my bike quick release or through axle?

If you have rim brakes, you will have a quick release skewer. If you have disc brakes you will most likely have thru axle skewers. If you have a disc brake older than 2019, you may have a quick release skewer, but disc brake road bikes made today are generally thru axle.

What bearings are used in bikes?

The different types of bearing used on a bike. Loose ball, caged ball, bushings, needle, and cartridge are the main styles of bearing founds in cycling frames and components.

What is a cartridge bearing?

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.

How does a bearing work?

Bearings reduce friction by providing smooth metal balls or rollers, and a smooth inner and outer metal surface for the balls to roll against. These balls or rollers “bear” the load, allowing the device to spin smoothly.

What connects the wheel to the axle?

The CV joint is what connects the axle and wheel together. And it is the CV joint that must be maintained in order for the axles to do their job properly.

What connects to the wheel hub?

The wheel hub is responsible for connecting a wheel to a vehicle. As a result, it connects to both the wheel and the vehicle itself. The wheel hug connects to the vehicle’s wheel axle, this is located on the brake disc side of the chassis. The tyres are then connected to the wheel hub assembly with studs.

What is the part that connects to the wheel hub?

Wheel Studs



The wheel studs are an integrated part of the wheel hub. These studs are what connect the wheel to the wheel hub assembly.

How do you use a through axle?

Quote from video: Now to use them very simply you unscrew anticlockwise. Until the lever stops moving out so probably about a centimeter or so at that point you can then simply.

What part of a bike is an axle?

A bike axle is a component within the hub, and it is the center point around which the hub bearings rotate. To allow for freer rotation, bearing cones are screwed onto the threaded bike axle on either side of the hub.

Why do road bikes have over axles?

How do I know if my bike has a through axle?

Your bike has a thru axle if the “drop out” is a hole, rather than a U-shaped dropout. This provides added security because even if the lever on the end of the thru axle flips open, it is still threaded into the frame, holding your wheel on.

Is hub the same as axle?

Hubs connect the axle to the wheel and allow the wheel to spin smoothly with the help of a bearing. A hub has a wheel flange on one end for mounting the brake rotor or brake drum and the wheel. On the other end, a hub has a wheel bearing inside or over it.

What is the advantage of hub reduction axle?

One advantage of a hub reduction or planetary drive rear axle is that the input torque gets reduced twice. First in the differential centre and then through the planetary drive wheel ends. Another advantage, especially for trucks like this one that operate out of mines and quarries, is the high ground clearance.

Can you use thru axle on quick release?

Quote from video: That allows you to use a quick release skewer. On a thru axle. Wheel. It works very simply i know some other brands make these basically all that you have to do is slide this adapter into the hub.

The easiest way to tell is if you are able to remove your wheel and replace it without any tools. There will be a lever that you can open and twist. This will undo the metal skewer. When you look at a quick-release system, you will see an acorn nut on one side and the lever on the other side.
