E&B深沟球轴承的外形尺寸公差和旋转精度公差按国标GB/T307.1分为PO、P6、P5、P4、P2五个公差等级。它们等同于国际标准IS0492、德国标准DIN620，日本工业标准JISBl514以及美国国家标准ANSI/AFBMASTD20的相应公差等级。这些公差等级和ISO等标准的对照如表3.1所示。详细的公差值如表3.2和表3.3所示。表3.1 标准公差等级对照 标准号公差等级GB/T 307.1 06542JISB1514 06542ISO49206542DIN620P0P6P5P4P2ANSI/AFBMASTD20ABEC-1ABEC-3ABEC-5ABEC-7ABEC-9表3.2 内圈公差 单位:(units)μm公差等级dmmdmphttp://www.ycbearings.com/Images/3dshttp://www.ycbearings.com/Images/3aVdspVdmpKiaSdSiaBVhttp://www.ycbearings.com/Images/3 VBS开式直径系列GB/T307.1超过到上偏差下偏差上偏差下偏差90.12,3,4Max.上偏差下偏差Max.Max.02.5101830101830500000-8-8-10-12 101013158810126689668910101315 0000-120-120-120-1201520202062.5101830101830500000-7-7-8-10 991013778105568556867810 0000-120-120-120-1201520202052.5101830101830500000-5-5-6-8 55684456445633344445778877880000-40-80-120-120555542.5101830101830500000-4-4-5-60000-4-4-5-6445633443344222.532.52.534334433440000-40-80-120-1202.52.52.5322.5101830101830500000-2.5-2.5-2.5-2.50000-2.5-2.5-2.5-2.5 2.52.52.52.52.52.52.52.51.51.51.51.51.51.52.52.51.51.51.51.51.51.51.51.50000-40-80-120-1201.51.51.51.5α 仅适用于4级、2级直径系列0、1、2、3和4。 表3.3 外圈公差 单位:(units)μm公差等级DmmDmphttp://www.ycbearings.com/Images/3dshttp://www.ycbearings.com/Images/3aVadspVdmpKeaSDSeaCShttp://www.ycbearings.com/Images/3VCS开式闭式直径系列B/T307.1超过到上偏差下偏差上偏差下偏差90.12,3,40,1,2,3,4Max.上偏差 下偏差Max.Max.02.5618305061830508000000-8-8-9-11-13 1010121416889111366781010101216206678101515152025 与同一轴承内圈的Bs http://www.ycbearings.com/Images/31相同 与同一轴承内圈的 Vbs 相同 62.51618305061830508000000-7-7-8-9-11 991011147789115567899101316556788891013 52.5618305061830508000000-5-5-6-7-9 556794455744557 3334555678888888888105555642.5618305061830508000000-4-4-5-6-700000-4-4-5-6-7445673345533455 222.533.53345544444555552.52.52.52.5322.5618305061830508000000-2.5-2.5-4-4-400000-2.5-2.5-4-4-4 2.52.54442.52.54442.52.54441.51.52221.51.52.52.541.51.51.51.51.51.51.52.52.541.51.51.51.51.5α 仅适用于4级、2级直径系列0、1、2、3和4。宁波金百联轴承有限公司总机电话：022-58059053 58059268 13102005112 87220519 销售电话：022-58059063 87222422（直拨）58059268 58059053 13102005112 87220519（转分机）采购部电话：022-87221977传真：022-23707785地址：天津市南开区华苑国际创业中心海泰信息广场B座212室E-mail：web@nskpc.com网址：www.nskpc.com www.nkspc.com 金百联特种非标轴承网: www.skf365.com
