                产品详细

                  高速精密角接触球轴承,主要用于载荷较轻的高速旋转场合,要求轴承高精度、高转速、低温升低振动和一定的使用寿命。常作高速电主轴的支承件成对安装使用,是内表面磨床高速电主轴的关键配套件。角接触球轴承分单列角接触球轴承和双列角接触球轴承。角接触球轴承主要技术指标:1.轴承精度指标:超过GB/307.1-94P4级精度2.高速性能指标:dmN值1.3~1.8x106/min3.使用寿命平均:大于1500h

                  高速精密角接触球轴承,有背对背、面对面和串联排列三种。背对背(两轴承的宽端面相对)安装时,轴承的接触角线沿回转轴线方向扩散,可增加其径向和轴向的支承角度刚性,抗变形能力大;面对面(两轴承的窄端面相对)安装时,轴承的接触角线朝回转轴线方向收敛,其支承角度刚性较小。由于轴承的内圈伸出外圈,当两轴承的外圈压紧到一起时,外圈的原始间隙消除,可以增加轴承的预加载荷;串联排列(两轴承的宽端面在一个方向)安装时,轴承的接触角线同向且平行,可使两轴承分担同一方向的工作载荷。但使用这种安装形式时,为了保证安装的轴向稳定性,两对串联排列的轴承必须在轴的两端对置安装。
