This listing contains a range of bearings to suit many bicycles. Each bearing is SOLD INDIVIDUALLY in quantities of 1. The bearings are listed by size & Bearing Number, for example 8x16x5mm - 688.

Once the bearing size is selected you can then select the Bearing Type which will only display the available options depending on which size you have selected. We have an explanation for each bearing type below.

All bearings on this listing are rubber sealed.

Please contact us if you are unsure of what bearings are required to suit your application.

Bearing Types

Chrome Steel

SAE 52100 Chrome Steel is the most common material used in deep groove ball bearings. This type of steel is useful in most applications, it's not recommended for use in fishing reels or any environment where it is exposed to water, it has low corrosion resistance.

Advantages are high hardness for long life, low cost for high performance, operates at temperatures up to 150c, lower noise and higher hardness compared to stainless steel.

When selecting this option, you are receiving an ABEC 3 rated chrome steel bearing that is pre-lubricated and ready to use.

Ceramic Hybrid

Our Ceramic Hybrid Bearings are constructed with Chrome Steel Rings and Si3N4 Ceramic Balls. There are many different options on this listing, some have chrome steel retainers whilst others have PA46 Nylon retainers, the ABEC ratings vary depending on which option is selected. Please contact us if you would like information on a particular bearing, we also have all bearings listed individually on our eBay store.

Ceramic Hybrid bearings can run at higher RPM's than steel bearings due to the lower centrifugal force generated by ceramic balls, they are lighter and harder than steel. Ceramic bearings are less subjected to ball skidding under initial torque / acceleration and they do not suffer from heat expansion. These 2 factors contribute to wear and when used in the right conditions a ceramic bearing will outlast chrome steel or stainless bearings.

Ceramic balls are corrosion resistant and non magnetic.

Seal Types

PTFE Contact Rubber Seals

The PTFE Rubber is bonded to a metal washer, the inner lip of the seal makes contact with the inner ring of the bearing to provide an effective seal against smaller particles such as dirt and dust, whilst protecting the lubricant from contamination and from leaking.
