Premium quality bearings have higher precision and RPM, which means they can rotate faster and last longer than normal ones.
If you need high-quality bearings, please choose the Premium option.
If you do not have high requirements for bearing precision and speed, you can choose the Normal option, which is cheap and cost-effective.
All Premium quality bearings use TN cages, and Normal quality bearings use steel cages.
