2.Commercial packing: 1pc/plastic bag+ single color box+ carton + plywood pallets.

3.According to customer's requirements.

Installation precautions
1.Avoid strong impact since the contact surface between the bearing raceway surface and the rolling element is close to point contact. Excessive impact force will cause indentation on the contact surface,so knock or drop impact must be avoided

2.Avoid dust entering the bearing.If dust enters the bearing during use the raceway surface and rolling element surface will be damaged, resulting in abnormal noise or poor rotation of the bearing.
