調(diào)心球軸承外圈滾道呈球面，具有調(diào)心性能，因此可自動(dòng)調(diào)整因軸或外殼的撓曲或不同心引起的軸心不正。 調(diào)心球軸承是外圈滾道加工成球面形、內(nèi)圈有兩條深溝滾道的雙列球軸承，具有調(diào)心性能。其主要用于承受徑向負(fù)荷，在承受徑向負(fù)荷的同時(shí)，也可承受少量的軸向負(fù)荷，但一般不能承受純軸向負(fù)荷，其極限轉(zhuǎn)速較深溝球軸承低。該類軸承多用于在負(fù)荷作用下易發(fā)生彎曲的雙支承軸上，以及雙承座孔不能保證嚴(yán)格同軸度的部件里，但內(nèi)圈中心線與外圈中心線的相對(duì)傾斜度不得超過3度。 主要用途:機(jī)電設(shè)備、塑料機(jī)械、辦公器械、紡織機(jī)械傳動(dòng)軸、醫(yī)療器械、健身和運(yùn)動(dòng)器材。型號(hào)有：NKI10/20 NKI100/30 NKI100/40 NKI12/16 NKI12/20 NKI15/16 NKI15/20 NKI17/16 NKI17/20 NKI20/16 NKI20/20 NKI22/16 NKI22/20 NKI25/20-TV NKI25/30 NKI28/20-TV NKI28/30 NKI30/20-TV NKI30/30-TV NKI32/20 NKI32/30 NKI35/20-TV NKI35/30 NKI38/20 NKI38/30 NKI40/20-TV NKI40/30-TV NKI42/20 NKI42/30 NKI45/25-TV NKI45/35-TV NKI5/12-TV NKI5/16-TV NKI50/25 NKI50/35 NKI55/25-TV NKI55/35 NKI6/12-TV NKI6/16-TV NKI60/25 NKI60/35 NKI65/25 NKI65/35 NKI7/12-TV NKI7/16-TV NKI70/25 NKI70/35 NKI75/25 NKI75/35 NKI80/25 NKI80/35 NKI85/26 NKI85/36 NKI9/12 NKI9/16 NKI90/26 NKI90/36 NKI95/26 NKI95/36 NKIA59/22 NKIA5901 NKIA5902 NKIA5903 NKIA5904 NKIA5905 NKIA5906 NKIA5907 NKIA5908 NKIA5909 NKIA5910 NKIA5911 NKIA5912 NKIA5913 NKIA5914 NKIB59/22 NKIB5901 NKIB5902 NKIB5903 NKIB5904 NKIB5905 NKIB5906 NKIB5907 NKIB5908 NKIB5909 NKIB5910 NKIB5911 NKIB5912 NKIB5913 NKIB5914 NKIS15 NKIS17 NKIS20 NKIS25 NKIS30 NKIS35 NKIS40 NKIS45 NKIS50 NKIS55 NKIS60 NKIS65 NKS20 NKS22 NKS24 NKS25 NKS28 NKS30 NKS32 NKS35 NKS37 NKS40 NKS43 NKS45 NKS50 NKS55 NKS60 NKS65 NKS70 NKS75
