為保證nsk軸承的長(zhǎng)壽命，不能滿(mǎn)足于般的安裝與調(diào)整要求，宜重點(diǎn)采取以下幾項(xiàng)措施：將nsk軸承按其過(guò)盈配合表面的尺寸分組，每組中又將軸承按其游隙大小順次排列。將相應(yīng)的軸或座孔直徑作同樣分組。將過(guò)盈配合表面尺寸大的軸承組與直徑大的軸組或座孔組對(duì)應(yīng)選配，而尺寸小的與直徑小的對(duì)應(yīng)組選配。在相配的每個(gè)對(duì)應(yīng)組中，將游隙大的nsk軸承取較緊的配合，游隙小的nsk軸承取較松的配合。這樣選配的結(jié)果，使得在同批安裝的機(jī)器中，nsk軸承的配合過(guò)盈較為致，既不過(guò)松，也不過(guò)緊，游隙也較為均勻致，從而保證nsk軸承安裝后的預(yù)應(yīng)力合宜，并避免蠕動(dòng)、套圈脹裂、因游隙不當(dāng)而產(chǎn)生的沖擊、振動(dòng)或發(fā)熱、抱合等非正常軸承失效的發(fā)生。
