Precautions when installing 6003 deep groove ball bearings

(1) Avoid strong impact
Since the contact surface between the bearing raceway surface and the rolling elements is close to point contact, excessive impact force will cause indentations on the contact surface, so knocking or dropping must be avoided.

(2) Prevent dust from entering the bearings
If dust invades the inside of the bearing during use, it will cause damage to the raceway surface and rolling element surface, causing abnormal noise and poor rotation of the bearing.

NSAR premium 6003 bearings is made in China and 6213 bearing Made of bearings steel,bearings steel with higher and more uniform hardness and abrasion resistance.The most rare is that of bearings steel with ultra-high hardness at the same time,have very strong elasticity.The assurance of hardness can prolong the service life of bearings.
