产品介绍
NSK推力轴承结构·型式和特征
推力球轴承
推力球轴承，根据外圈(机壳座堑、固定圈)座的形状，分为平面座型和调心球面型。可以承受轴向载荷，但不能承受径向载荷。
推力球轴承的轴承系列如表1所示。
单向推力球轴承，通常如表2所示，使用冲压保持架和铜合金车制保持架。
双向推力球轴承的保持架，与相同系列的单向推力球轴承同样。
尺寸表记载的额定载荷，以表2的保持架区分为基准。
另外，相同型号的轴承因保持架不同，球的个数也有变化，这种情况下，额定载荷与尺寸表记载的数值相异。
推力圆柱滚子轴承
使用圆柱滚子的推力轴承，只可以承受轴向载荷，适于高载荷用途，轴向刚度也大。
使用铜合金车制保持架。
推力调心滚子轴承
使用球面滚子的推力轴承，具有调心性。不受安装误差、轴挠曲的影响。除传统型之外，有以高承载设计，使用冲压保持架的H型。(公称代号末尾标有H的记号)。
滚子头部和内圈挡边之间，保持架与导套之间的滑动接触面等，润滑剂不易润滑的部分多，因此，即使是低速旋转也采用油润滑。
传统型保持架为铜合金车制保持架。
尺寸精度·旋转精度
推力球轴承、推力圆柱滚子轴承
推荐配合
推力球轴承、推力圆柱滚子轴承、推力调心滚子轴承
与安装有关的尺寸
推力调心滚子轴承的安装关系尺寸，编录于轴承尺寸表。另外，承受重载荷情况下，需要足以支持轴圈挡边部分的轴肩尺寸和强度。
容许调心角
推力调心滚子轴承的容许调心角，因轴承的尺寸系列而异。普通 载荷的场合，大约1°～2°。
最小轴向载荷
推力轴承，为防止滚动体与套圈之间的滑动，须使轴承承受一定程度以上的轴向载荷。有关详细请参照A99页。

NSK集团简介
NSK自1916年在日本率先开始生产轴承以来，作为日本的轴承先锋，开发与提供各类轴承，为产业的发展和机械的进步做出了巨大贡献。NSK还利用生产轴承锤炼出的精密加工技术，从很早以前就开始通过向汽车零部件、精密机械产品、电子应用产品等领域的进军，推动多方位的事业拓展。
NSK于上世纪60年代初在美国密歇根州安阿伯设立了销售公司，以此为开端，正式迈开建立并运营海外事业网点的步伐。1970年，在巴西圣保罗市郊外建立了生产基地，其后，又在北美、英国、亚洲各国开辟了新的生产基地。另外，1990年，NSK收购了拥有欧洲硕大轴承厂家RHP公司的UPI公司。横跨欧洲市场全境的NSK生产基地及销售网点，正进一步巩固着NSK在欧洲市场的优势地位。
90年代中期开始，NSK加快了中国及亚洲地区的事业拓展，特别是针对急速成长的中国市场，建立起能够自主研发到销售、技术服务的全套经营体制。
NSK将在全集团范围内进一步贯彻遵纪守法的原则，秉持企业的社会责任，不断推进事业活动。NSK通过全球网络，努力促进开发能力、生产能力、销售能力及经营管理能力的相互强化，争取更大地进步。
