振动游隙
深沟球轴承无预负菏状态的游隙适用表
Redial Clearance Value

轴承内径 mm		C1		C2		C3		C4		C5
Over	To	Min	Max	Min	Max	Min	Max	Min	Max	Min	Max
10	18	0	9	3	18	11	25	18	33	25	45
18	24	0	10	5	20	13	28	20	36	28	48

备注: 游隙测量时,需加上测量负菏产生的径向内部游隙增加量进行修正.
Note: When measuring the clearancr,we should take into considerration of the
Extra clearance arisen from the measuring load.
