單列角接觸球淮安INA軸承能承受單向軸向載荷。單列角接觸球軸承通常與其余軸承成對(duì)使用。這種軸承是不可分割的設(shè)計(jì)，內(nèi)外環(huán)兩側(cè)的軸肩尺寸是不同的。肩部越小，滾珠軸承越多，承載能力越高。

Single row angular contact ball Huaian INA bearing can bear unidirectional axial load. Single row angular contact ball bearings are usually used in pairs with other bearings. The bearing is an inseparable design, and the shoulder sizes on both sides of the inner and outer rings are different. The smaller the shoulder, the more ball bearings, the higher the load-carrying capacity.

該軸承具有接觸角，適用于承受軸向載荷或單向復(fù)合載荷。

The bearing has contact angle and is suitable for bearing axial load or unidirectional composite load.

在結(jié)構(gòu)中，軸承在承受徑向載荷后會(huì)軸向分離，所以兩個(gè)軸承將成對(duì)使用，或者兩個(gè)以上的軸承將成對(duì)使用。單列角接觸球軸承采用預(yù)緊法可提高剛度，適用于高精度機(jī)床主軸。

In the structure, bearings will be axially separated after bearing radial load, so two bearings will be used in pairs, or more than two bearings will be used in pairs. Single row angular contact ball bearings can improve stiffness by pre-tightening method, which is suitable for spindle of high precision machine tools.

通常，接觸角為30度（代碼A UU）和40度（代碼B）角接觸球軸承保持架。然而，合成樹(shù)脂保持架或聚酰胺保持架也在不同的條件下使用。尺寸表中記錄的基本額定載荷基于保持架面積。

Usually, contact angles are 30 degrees (code A UU) and 40 degrees (code B) angular contact ball bearing cages. However, synthetic resin cages or polyamide cages are also used under different conditions. The basic rated load recorded in the dimension table is based on cage area.

萬(wàn)向成對(duì)軸承主要成對(duì)使用。一般配套淮安INA軸承均經(jīng)過(guò)特殊加工。當(dāng)軸承彼此靠近安裝時(shí)，任何組合都可以在不使用墊圈或類似裝置的情況下實(shí)現(xiàn)給定的內(nèi)部間隙或預(yù)加載，以及平均負(fù)載分布。

Universal paired bearings are mainly used in pairs. Generally matching Huaian INA bearings are specially processed. When bearings are installed close to each other, any combination can achieve a given internal clearance or preload, as well as an average load distribution without using gaskets or similar devices.

當(dāng)單個(gè)軸承的承載能力不足時(shí)（槽結(jié)構(gòu)），或當(dāng)使用兩個(gè)方向的組合荷載或軸向荷載（背對(duì)背或面對(duì)面配置）時(shí)，使用匹配軸承。

Matched bearings are used when the bearing capacity of a single bearing is insufficient (groove structure), or when combined loads in two directions or axial loads (back-to-back or face-to-face configuration) are used.

背靠背配置：后碼為db（如7000/db），背靠背軸承的載重線與軸承軸分離。兩個(gè)方向的軸向載荷都可以承受，但每個(gè)方向的載荷只能由一個(gè)淮安INA軸承承受。背對(duì)背安裝軸承提供相對(duì)剛性的軸承配置，可以承受傾覆力矩。

Back-to-back configuration: the rear code is DB (e.g. 7000/db), the load line of back-to-back bearing is separated from the bearing shaft. Axial loads in both directions can be sustained, but loads in each direction can only be sustained by a Huaian INA bearing. Back-to-back mounted bearings provide relatively rigid bearing configurations that can withstand overturning moments.

面對(duì)面配置：后代數(shù)為df（如7000/df），面對(duì)面匹配軸承的載荷集中在軸承軸上。兩個(gè)方向的軸向載荷都可以承受，但每個(gè)方向的載荷只能由一個(gè)軸承承受。這種配置不像背對(duì)背配對(duì)那樣剛性，不適合傾覆力矩。該結(jié)構(gòu)的剛度和傾覆力矩不如DB結(jié)構(gòu)。軸承能承受雙軸載荷。

Face-to-face configuration: the number of offspring is DF (e.g. 7000/df), and the load of face-to-face matched bearings is concentrated on the bearing shaft. Axial loads in both directions can be sustained, but loads in each direction can only be sustained by one bearing. This configuration is not as rigid as back-to-back pairing and is not suitable for overturning moment. The stiffness and overturning moment of this structure are not as good as those of DB structure. Bearings can withstand biaxial loads.

系列配置：后碼為dt（如7000/dt）。在串聯(lián)結(jié)構(gòu)中，載荷線平行，徑向和軸向載荷由軸承均勻分擔(dān)。然而，淮安INA軸承組只能承受作用于一個(gè)方向的軸向載荷。如果軸向載荷的作用方向相反或存在復(fù)合載荷，則bi須添加第三個(gè)具有相對(duì)串聯(lián)對(duì)調(diào)整的軸承。該結(jié)構(gòu)還可用于同一支架上串接三個(gè)或三個(gè)以上軸承，但只能承受單向軸向載荷。通常情況下，為了平衡和限.制軸的軸向位移，應(yīng)安裝另一個(gè)軸承來(lái)承受另一個(gè)方向的軸向載荷。

Series Configuration: The rear code is DT (e.g. 7000/dt). In the series structure, the load lines are parallel, and the radial and axial loads are evenly shared by the bearings. However, Huaian INA bearing group can only bear the axial load acting in one direction. If the direction of action of the axial load is opposite or there is a composite load, the Bi must add a third bearing with relative series pair adjustment. The structure can also be used to connect three or more bearings in series on the same support, but can only bear unidirectional axial load. Usually, in order to balance and limit the axial displacement of the shafting, another bearing should be installed to bear the axial load in the other direction.
