Size
The vast majority of bearings used in skating applications are sized for 8mm axles; these are also known as standard 608 bearings. 7mm (627) bearings are comparatively uncommon by comparison, while other sizes for instance Micro (688) are only hardly ever noticed. As the only true restriction with regards to bearings, we advocate obtaining the size that your axles and wheels are developed to work with.
Components
Bearings are most efficient when friction is at its lowest, so materials play a pivotal function in efficiency. Many bearings are constructed from steel alloys which are challenging and affordable. Keep an eye out for components or coatings made from bronze, titanium, and specifically ceramic - these will enhance a bearing’s resilience, durability, and functionality. Ceramic bearings are broadly regarded as the best that money can buy.
Rating
Lots of manufacturers seek out an ABEC rating that scores bearings on a scale of 1-9. Larger ABEC scores indicate a a lot more precisely created bearing, on the other hand, the system was created for industrial applications, not skating. Therefore, a number of companies forgo ABEC ratings on their skate bearings and opt for “skate rated” labels that signifies that the bearing was tested and authorized for skating.
Number of Balls
Skate bearings traditionally have seven balls that supply a great balance of acceleration, top speed, roll, and durability. Six ball bearings use bigger balls that create significantly less friction and roll longer, creating them best for sustained skating at high speeds (think 27-in-5 or banked track). Eight ball bearings have smaller balls that far better withstand side loads, which tends to make them excellent for higher speed or aggressive turning (feel park skating). Derby is really a mixture of all of these points, so discover your magic number!
Serviceable vs Sealed
Serviceable bearings function removable shields or plastic retainers that permit you to clean and re-lubricate your bearings. Most high-end bearings are going to be serviceable to allow you to sustain optimal roll and extend the life from the bearing. Sealed bearings have non-removable shields that assistance preserve out dangerous debris, however they can't be cleaned and would need to be replaced when not performing as preferred. Sealed bearings are good for those skaters not thinking about bearing maintenance but are likely to lack the overall performance provided by serviceable bearings.
