  • Bearings have a couple of measurements that you should be aware of. 8mm, shown with these bearings, tells you the diameter of the inner hole. This diameter matches the diameter of the axle used on the trucks. 8mm axles are by far the most common.

              The next number is shown as an abec rating. This number classifies the precision of a bearing when manufactured. Abec1 is considered the lowest rating, and abec9 as the highest. An abec9 bearing will be ground or polished to a higher tolerance and in turn may be faster and last longer. A very precise bearing will have reduced friction, friction causes heat, and heat ultimately will cause bearings to fail.

             Ceramic bearings use balls that are made from a very precise ceramic material. This material will also run cooler than metal balls, and heat is what causes bearings to fail.

    We always recommend that you clean and lube bearings regularly. A well maintained Abec5 bearing will outlast an Abec7 bearing that is not maintained.

               The purpose of a radial bearing is to reduce rotational friction and support loads. This is achieved by using two races to hold the balls and to spread the load through the balls. As the bearing race rotates it causes the balls to rotate. The ball provides for substantially less rolling resistance and coefficient of friction than if two flat surfaces were rotating.

              Single-row, deep groove radial ball bearings are the most common bearing type, having a wide range of applications. Radial bearings are made with very high levels of precision and used in applications where rotational performance and low torque is necessary, but load is a secondary issue. Deep-groove bearings however do have higher load ratings for their size than shallow-groove ball bearings, but are also less tolerant of misalignment.
