How Often Should I Change My Scooter Bearings?
There is no set time as to when you should change your bearings. A set of bearings lasts depending on how much you skate and how well you take care of your bearings. There are some ways to figure out if your bearings are on their way out however. If you start hearing a crunch-like sound or your wheels or you don't seem to be able to spin them as freely. It means that your bearings are most likely gone and it would be a good idea to get a new set.
What Size Are Scooter Bearings?
Most of the scooter bearings are 8mm in size, made to fit an 8mm axle however, there are some bearings that are 10mm. The 8mm size of bearing is used in many different disciplines such as longboarding, skateboarding and rollerblading.. In fact many scooter riders use bearings that are made by skateboard brands.
Different Types of Bearings
Scooter bearings can be made using two different materials which determine the quality and durability of the bearing. Bearings can come with either 7 or 8 balls made from either steel or ceramic. The ceramic bearings are extremely durable and a lot smoother than steel bearings however, they are also much more expensive which is the reason why most people choose steel bearings.
Most bearing brands use ABEC rating to assess the precision of a bearing. The ABEC rating goes from 1-9 and the lower the rating of the bearing, the less precise are the bearings. The most commonly used bearings are either Abec-7 or Abec-9 as they are very durable and affordable.
