常用的INA调心球轴承润滑的检查方法INA轴承是采用稀油脂及油雾润滑方式的一种轴承。INA轴承应用领域：德国INA轴承的产品涉及行业包括：农业机械行业、建筑行业、水力和风力工程行业、工程机械行业、机床及制造机械行业、材料处理及包装业、港口工程行业、电动工具行业、变速箱行业、半导体行业、泵与风机行业、工业机器人及自动化行业、橡胶、塑料及化工行业、纺织行业、拖拉机行业、木工机械行业等。在这些行业中，德国INA轴承都得到了广泛的应用。检查INA轴承的方法：检查前需先清洁机器表面，然后拆INA卸轴承周边的零件。油封是很脆弱的零件，因此需小心的拆卸，切勿过度施力，然后仔细的检查油封及其周边的零件，如果已呈现出不良的症状时，务必更换掉，不良的油封会导致调心球轴承的损坏及严得的设备停机。沾上点点润滑剂在两指之间摩擦，若有污染物存在，可感觉出来，或在手背上涂一层润滑剂，然后封光检查。机油润滑的INA轴承在泻除旧机油后，可能的话，再灌入新鲜的机油并让机器在低转速旋转几分钟。尽可能使机油收集残留的污染物，然后再泻除这些机油，机油在使用前最好先经过滤。滑脂润滑的轴承在更换滑脂时所使用的乔除器应避免带有棉质物接角到轴承的任一部位，因为这些残留的纤维可能楔入于滚动件之间并且造成损坏，尤其是小调心球轴承的应用更需注意此问题。在一些特殊使用条件下，将少量固体润滑剂加入润滑脂中，如加入3~5％的1号二硫化钼可减少磨损，提高抗压耐热能力。粘度是润滑油的重要特性，粘度的大小直接影响润滑油的流动性及摩擦面间形成的油膜厚度，工作温度下润滑油的粘度一般是12-15cst。转速愈高应选较低的粘度，负荷愈重应选较高的粘度。油润滑方法包括：a.油浴润滑油浴润滑是最普通的润滑方法，适于低、中速的润滑，调心球轴承一部分浸在由槽中，润滑油由旋转的零件带起，然后又流回油槽油面应稍低于最低滚动体的中心。b.滴油润滑滴油润滑适于需要定量供应润滑油得INA轴承部件，滴油量一般每3-8秒一滴为宜，过多的油量将引起轴承温度增高。c.循环油润滑用油泵将过滤的油输送到部件中，通过后的润滑油再过滤冷却后使用。由于循环油可带走一定的热量，使降温，故此法适用于转速较高的轴承部件。d.喷雾润滑用干燥的压缩空气经喷雾器与润滑油混合形成油雾，喷射中，气流可有效地使降温并能防止杂质侵入。此法适于高速、高温部件的润滑。e.喷射润滑用油泵将高压油经喷嘴射入，射入中的油经另一端流入油槽。在轴承高速旋转时，滚动体和保持架也以相当高的旋转速度使周围空气形成气流。检查调心球轴承时，千万不要让轴承暴露于污染物或湿气的环境。如果工作中断时，应以油纸塑胶片或类似材料覆曾机器。若在不用拆卸而可能执行检查的情形下清洗无掩蔽的INA轴承的，要以涂敷用的刷子沾上石油溶剂（whitespirit）清洗，再以一块不起毛的布料擦干或用压缩空气吹干（注意不要让轴承组件起动旋转）。不可清洗加密封盖或防尘的轴承；只擦拭其外部表面即可。如果INA轴承呈受损情形时即需更换掉。在定期的停机保养时期内更换调心球轴承损坏所选成的突然停机之损失来得经济多了。INA轴承型号尺寸表：轴承型号品牌内径(mm)外径(mm)厚度(mm)10XS18INA27.025647.6312.7NKIS65INA659528RNA6915-ZWINA8510554RNA6904INA253730RNA4919INA11013035RAL012-NPPINA19.054224.6PI081216INA12.719.0525.4IR30X38X20-IS1INA303820IR60X68X45INA606845IR12X16X20INA121620RNAO18X30X24-ZW-ASR1INA183024NA4909-RSRINA456823CSXC100INA254273.059.525CSXB042INA107.95123.8257.938RCRB25/57-FA106INA2557.331K60X68X25INA6068251025INA124.993270130SL04160-PPINA16022080FTO4INA12.723.8259.525MW2INA50.893.6834.925K60X68X25INA606825B34INA65.0875100.81322.225RNAO90X105X26INA9010526IR20X25X26,5INA202526.5NKIS40INA406522RNA4901-RSRINA162413CSEC055INA139.7158.759.525207-KRR-AH03INA357225205-KRRINA255221D10INA4.2333350.01315.875CSED045INA114.3139.712.7CSXD180INA457.2482.612.7D21INA44.4578.58820.65W2INA50.875.4119.05RASE45-FA125INA89456-MINA280520145K81134-TVINA17021514BCE98INA14.28819.0512.7SCE1211-PINA19.0525.417.46HN5020INA505820SCE1012-PPINA15.87520.63819.05RNAO35X45X26-ZW-ASR1INA354526NA4904-2RSRINA203718NA4828INA14017535NA4900INA102213NKI70/35INA709535K30X34X13INA303413K20X26X12INA202612CSCA120INA304.8317.56.35K7X10X8-TVINA7108CRB20/83INA2083.636.2RAE15-NPP-FA106INA154028.6GE65-214-KTT-BINA6512566GE35-KRR-B-2CINA357251.3GE50-KRR-B-FA101INA509062.8PNA15/32INA153216SL183009INA457523AXK5070INA50703IR17X20X16,5INA172016.5IR190X210X50INA19021050CSCC100INA254273.059.525IR50X55X20-IS1INA505520SK014-205-KRR-BINA22.2255225.4GSH20-2RSR-BINA204728GAY108-NPP-B-AS2/VINA38.18039.5GT6INA20.637537.31314.3DL55INA54.9918828D24INA49.212581.76320.65919INA94.99614032.5915INA75.0062110272041INA42.862560.32514.288IR90X100X30INA9010030NCS2820INA44.4558.73831.75NCS2620INA41.27555.56331.75NA4919INA9513035IR25X30X26,5INA253026.5NK68/25INA688225BCE45INA6.3511.1127.938SCE148-PPINA22.22528.57512.7SCE2420INA38.147.62531.75SL181848-EINA24030028K155X163X26INA15516326SCE2012-PINA31.7538.119.05IR60X68X35INA606835GE60-KTT-BINA6011077.9IR20X25X16-IS1INA202516RNAO12X22X12-TVINA122212NA4900-RSRINA102214IR25X30X17INA253017NK5/10-TVINA51010SCE109-PINA15.87520.63814.288SCE2110INA33.33841.27515.875HK2524-2RSINA253224SL182928INA14019030SL04200-PPINA20027080CSEF060INA152.4190.519.05CSXF120INA304.8342.919.05CSXF075INA190.5228.619.05CSXD120INA304.8330.212.7CSXU060-2RSINA152.4171.4512.7SCE2012-PINA31.7538.119.05RNA4918INA10512535IR25X29X20INA252920YRTS260INA26038555RA010-NPPINA15.8754028.6RNAO60X78X20INA6078202922INA110.007145252907INA35.00125516NA49/32INA325220NK22/20INA223020NK15/16INA152316BCE105INA15.87520.6387.938BK1015INA101415HK2220INA222820HK2210INA222810HK1412INA142012K40X47X20INA404720K20X28X16INA202816K19X23X17INA192317SL185030INA150225100GSH20-2RSR-BINA204728RNA6914-ZWINA80100542902INA15.01143112IR200X220X50INA200220504106INA29.99745318CSCA030INA76.288.96.35CSCG070INA177.8228.625.4GYE12-KRR-B-VAINA124025CSCA042INA107.95120.656.35K68X74X20INA687420CSXC040INA101.6120.659.525CSXB060INA152.4168.2757.938K81102-TVINA15283.5HW1/2INA12.733.3518.263FT29INA57.1594.46320.638NKI15/16INA152716RNA4864INA35040080NKS65INA658528SCE2410INA38.147.62515.875K26X30X17INA263017206-KRRINA306224CSCC042INA107.951279.525SL182917INA8512022SL183009INA457523HK5022-RSINA505822NKI28/20-TVINA284220PNA15/32INA153216ZKLDF460INA46060070K60X65X30INA606530GE25-KRR-B-FA101INA255244.5RALE25-NPP-BINA254725.5CSCD050INA127152.412.7RASE30-FA164INAXSU080188INA15022525.4DKLFA2080-2RSINA205235ZKLFA0850-2RSINA83220ZKLN60110-2ZINA6011045ZARF50115-L-TVINA5011578NKIB5911INA558038RTL41INA76.2119.86325.4GAY25-NPP-BINA255227SL024876INA380480100K26X30X17INA263017PNA17/35INA173516IR35X43X22INA354322IR10X14X12-IS1INA101412LR17X20X20,5INA172020.5PI060912INA9.52514.28819.05B25INA50.884.9422.22W5-1/2INA139.7204.855.7K58X65X18INA586518GAY107-NPP-B-AS2/VINA36.51257235NKXR35-ZINA354730ZARN3062-L-
