角接触球轴承是轴承的一种，它可同时承受径向负荷和轴向负荷。能在较高的转速下工作。接触角越大，轴向承载能力越高。高精度和高速轴承通常取15 度接触角。在轴向力作用下，接触角会增大。

　　Angular contact ball bearing is a kind of bearing. It can bear radial load and axial load simultaneously. It can work at higher speed. The larger the contact angle, the higher the axial bearing capacity. High precision and high speed bearings usually take 15 degree contact angles. Under axial force, the contact angle will increase.

　　轴承特点 Bearing characteristics

　　调心滚子轴承具有两列滚子，主要承受径向载荷，同时也能承受任一方向的轴向载荷。有高的径向载荷能力，特别适用于重载或振动载荷下工作，但不能承受纯轴向载荷。该类轴承外圈滚道是球面形，故其调心性能良好，能补偿同轴度误差。

　　The self-aligning roller bearing has two rows of rollers, which mainly bear radial loads and axial loads in any direction. High radial load capacity, especially suitable for heavy load or vibration load, but can not withstand pure axial load. The raceway of this kind of bearing outer ring is spherical, so its aligning performance is good, and it can compensate coaxiality error.

　　有两列对称型球面滚子，外圈有一条共用的球面滚道，内圈有两条与轴承轴线倾斜一角度的滚道，具有良好的调心性能，当轴受力弯曲或安装不同心时轴承仍可正常使用，调心性随轴承尺寸系列不同而异，一般所允许的调心角度为1——2.5度 ，该类型轴承的负荷能力较大，除能承受径向负荷外轴承还能承受双向作用的轴向负荷，具有较好的抗冲击能力，一般来说调心滚子轴承所允许的工作转速较低。

　　There are two rows of symmetrical spherical roller, the outer ring has a common spherical raceway, and the inner ring has two raceways inclined to the axis of the bearing, which have good alignment performance. The bearing can still be used normally when the axis is bent or installed with different alignment. The alignment varies with the bearing size series, and the alignment angle is generally allowed. Degree of 1 - 2.5 degrees, this type of bearing load capacity is larger, in addition to bearing radial load can also withstand two-way axial load, has a good impact resistance, generally speaking, aligning roller bearings allow a lower speed.
