What are the different types of bike bearings?

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 size bearings does my bike have?

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”.

Are all bike bearings the same?

Bicycles usually use ball bearings. However, many bicycles still use older, cup and cone system, where balls can (and should) be replaced with new ones when servicing bearings. This is the case with most Shimano hubs (wheels) – they still use the cup and cone system.

What type of bearings are used in wheels?

Most automotive wheel bearings are one of two basic designs: ball bearings or tapered roller bearings. Each type of bearing has pros and cons, depending on the application. Generally you’ll find ball bearings in passenger cars. These low-friction bearings are suitable for high engine speeds.

What are bicycle wheel bearings?

Wheel bearings keep your bike wheel spinning smoothly, with small ball bearings reducing friction. If your bike wheel is wobbling or isn’t spinning as freely as it should be, then your wheel bearings may be causing the problem.

How long do bicycle wheel bearings last?

Bike wheel bearings should be changed every 1 to 2 years, depending on their quality and riding habits. Assuming that they’re well-lubricated and properly maintained when needed, most ball bearing with steel races will stay in working condition for at least three to four years.

Are front and back wheel bearings the same?

Both are generally tapered roller bearings, both allow one part to spin relative to another. The front tends to have inner and outer bearings close to one another – on the wheel spindle – while the back will have an outer bearing at the wheel and the inner end will track in the side gear in the differential.
