The differences between normal and premium quality bearings.
1. Premium quality bearings have thicker outer rings and inner rings.
2. Premium quality bearings use better grease with higher dropping points (premium 130°c ,normal 110°c)
3. Premium quality bearings are carefully polished through more processes.
In general, premium quality bearings have higher precision and RPM, which means they can rotate faster, make lower noise, and last longer than normal ones.
If you need high-quality bearings, please choose the Premium option. On the other hand, If you do not have high requirements for bearing precision and speed, you can choose the Normal option, which is cheaper and cost-effective.
