Ball bearings for smooth operation
Steel versus ceramic
Steel ball bearings are the standard for reliability and affordability. Ceramic bearings are harder, lighter, and less susceptible to corrosion, popular among road cyclists seeking maximum efficiency. Bearings are used in headsets, bottom brackets, wheels, and pedals.
Loose balls versus cartridge
Loose balls are used in open bearings like older headsets and wheels. Cartridge bearings (sealed bearings) are replaced as a complete unit and are dust- and waterproof. Know the correct dimensions: inner and outer diameter and width.
Dimensions
Bearings are designated by a standard code specifying inner and outer diameter and width. Common sizes for wheels are 6000, 6200, and 6300 series. Different sizes are used for headsets. Measure the old bearing or check frame specifications.
Maintenance
Bearings should be regularly re-greased with grease for smooth rotation. Worn bearings make noise and have play. Clean the bearing housing with brake cleaner before greasing.
Bearings are essential for a smooth-running bike. Check bearings in wheels, headset, and pedals regularly for wear.
