These are the magical little circular things found in the centre of your wheel. There are different types of bearings which range in hardness, quality and material, but in simple terms, they are a set of metal balls (called ball bearings) which sit between 2 rings of metal, an outer and an inner. The ball bearings are sealed with a rubber ring outside to keep them free from dirt and dust. They’re cushioned in place with washers and there’s always a set of 2 on each wheel.

There’s no such thing as a truly waterproof bearing (not for skateboards and longboards anyway), some make this claim but after time water and grime does get in. This causes the bearing to run less efficiently and eventually fail. Its good to regularly clean the outside of your bearings to prevent this grime from being pushed inside. If you’ve got them wet, make sure they’re properly dried or replaced before you ride again. As a general rule of thumb, water is the enemy of the bearing.
