To retain certain clearances single bearings that are used in pairs have to be matched accordingly.為了維持定然的間隙，必需婚配呼應的是成對于使用的單個軸承。 For that reason single row angular contact ball bearings of the series 72 and 73 featuring contact angles of 40deg are available in a variant for use as a single bearing (suffix B) and in a universal matched variant to be used in pairs or sets (suffix BG).出于某個原因，作為一度繁多的軸承（后綴B）使用的一度變種，并以一種通用的婚配變種系列72，并設有73 40deg的接觸須的單行角接觸球軸承成對于或者成套（后綴使用BG）。
Single row angular contact ball bearings have a very limited ability to accommodate misalignments.單行角接觸球軸承有一度無比無限的威力，以順應平衡。 Therefore any operating misalignments applied to this bearing type creates additional forces subsequently reducing their service life and, additionally, generates higher running noise levels.因而這種軸承類型平衡創舉更多的部隊，隨即縮小其使用壽數，于是，發生更高的運轉樂音程度。
Where individual single row angular contact bearings or pairs of bearings are arranged Face to Face, up to 2 angular minutes misalignment from the centre position does not normally affect the bearings negatively.凡是單個列角接觸球軸承或者軸承對于陳列面對于面，同比增加2角沒有對于秒鐘從主干地位一般沒有會軸承發生反面反應。
However, when arranged in pairs Back to Back or Tandem or as Sets, spindle bearings must not run misaligned.但是，成對于陳列時前往或者并聯，或者將其安裝為，主光軸軸承，沒有得運轉對于齊。
Cages 籠
The NKE single row angular contact ball bearings, with normal tolerance class are fitted with Pressed Steel cages as standard.作為標準沖壓鋼維持架的NKE的單行角接觸球軸承與畸形的差役頭銜，都裝備。 Large types and sizes have machined Solid Brass cages (Suffix M) fitted as standard.大類型和范圍的加工液體黃銅維持架（后綴M）作為標準裝備。
Bearings used in Higher Precision or Machine in Tool Spindle applications are normally fitted with either Phenolic Resin (suffix TPA) or machined Solid Brass cages (suffix M).在更高的精密度，或者在刀具主光軸中的利用機使用的軸承一般采納要么電木樹脂（后綴TPA）的，或者加工液體黃銅維持架（后綴M）。
Some special applications have machined Solid Steel cages (suffix F) or Light Metal Alloy cages (suffix L) fitted as standard.一些特別的利用加工液體鋼維持架（后綴F）或者輕非金屬合金籠（后綴L）作為標準裝備。
Internal Clearnace 外部Clearnace
The axial play of angular contact ball bearings is achieved by adjusting one bearing against another.是經過調動人擁護另一度軸承角接觸球軸承的軸向間隙。 NKE single row angular contact ball bearings in universal design, with normal bearing mounting fits, are matched in pairs eFace" or "Back to Back" to give a small axial play. NKE的通用設計的單行角接觸球軸承與畸形軸承裝置適宜，在對于婚配任“面對于面ither "Face to ”或者“面對面”給一度小的軸向間隙。
The "normal" fits are: “畸形”千篇一概是：
Shaftfits: j5軸適
合：J5 Housing fits: J6屋宇適宜：J6
Special clearances 特別答應
NKE also produce upon request paired single row angular contact ball bearings to customers requirements and specifications. NKE還出具要求配對于單行角接觸球軸承存戶的要求和規范。
Bearing pairs (see drawing below)軸承雙（見圖紙上面）
Single row angular contact ball bearings in universal design, (suffix BG) and spindle bearings are frequently used in pairs or sets.單行角接觸球軸承通用設計（后綴為BG）和主光軸軸承時常成對于或者成套使用。 (see arrangements sketch below) （見上文調度寫生）
Tandem Arrangement并聯安排
Single row angular contact ball bearings in a tandem arrangement are used when the actual thrust force exceeds the thrust load capacity of a single angular contact ball bearing.單行角接觸球軸承在并聯安排時所使用的實踐推力超越一度繁多的角接觸球軸承推力載荷威力。 These該署
thrust forces are accommodated in one direction only and are distributed equally to both bearings.寓居在只要一度位置的推力，并均勻調配給兩個軸承。
Single row angular contact ball bearings in tandem arrangement must always be adjusted against another bearing inversely arranged for shaft guidance in the opposite direction.單行角接觸球軸承并聯安排必需一直另深溝軸承一度軸承對于軸的指點成正比調度在不同的位置調動。
