滚珠丝杆支撑轴承

　　滚珠丝杆支撑轴承的接触角为60度，可承载较大的轴向载荷，并主要用于各类精密机床的滚珠丝杆，也可用于转速不高但轴向载荷较大的磨头电机中。其尺寸精度达到P4级，带有密封结构的滚珠丝杆轴承

The ball screw support bearing has a contact angle of 60 degrees and can carry a large axial load. It is mainly used for ball screws of various precision machine tools, and can also be used for grinding head motors with low speed but large axial load. The ball screw bearing can reach a dimensional accuracy of P4 with a sealed structure.
