产品简介

单列角接触球轴承可同时承受径向和一个方向轴向载荷,极限转速高,主要用于精密机床和其他高精度、高转速的部位。该类轴承在承受径向载荷时,轴承内圈会产生轴向分力,因此,单列角接触球轴承通常需要与能承受反方向轴向的轴承配套安装使用。

安装说明
高速角接触球轴承    H719系列;H70系列;HC719系列;HC70系列;B70系列
结构特点:采用小球设计的LYZYC高速系列;
套圈材料采用欧洲产高纯净轴承钢,配合特殊的热处理工艺,冷处理工艺以及材料改性技术,使得该系列轴承疲劳寿命大幅度提高。
接触角分15º和25º,成对使用可承受轴向负荷和径向负荷或合成负荷。
保持架采用外圈引导的酚醛树脂夹布胶木保持架;可长期在120ºС以下稳定工作。
滚动体材质有两种:钢球(H719,H70);陶瓷球(HC719,HC70)
一般中高速工况推荐选用钢球;
高速及特殊工况可选用陶瓷球。
速度因子:滚动体为钢球时(H719,H70)
油脂润滑  DmN≤1200000  即 极限转速N≤1200000/Dm  Dm—轴承中径油(最少量)润滑    DmN≤1800000
滚动体为陶瓷球时(HC719,HC70)
油脂润滑  DmN≤1400000  即 极限转速N≤1400000/Dm  Dm—轴承中径油(最少量)润滑    DmN≤2200000
适用范围:主要用于高转速,高精度旋转等工况。例如:数控加工中心主轴,磨削用高速电轴,磨床砂轮主轴,高速精密机械等。
可提供预装油脂的密封式轴承。
超长寿命轴承专为转速和载荷 要求*的工况而设计。这种轴承的 套圈材料为Cronidur 30,一种高氮 不锈钢。与传统的滚动轴承钢100Cr6相比,Cronidur 30的金相组织结构 更好,可确保运行温度较低并且承受更高的接触应力。
材料疲劳寿命的测试值远远超出了计算值,可以认为在实际应用中轴承是可靠的。在混合摩擦的情况下,这种轴承钢比标准轴承钢100Cr6的疲劳极限高10倍。同样这种轴承钢的赫兹应力,抗腐蚀性和热硬度也明显优于普通滚动轴承钢。
与普通轴承相比,超长寿命轴承的使用寿命更长,从而降低了系统成本。原则上,所有的主轴轴承都提供相应的产品。要充分发挥轴承的良好性能,必须正确设计轴承的周边结构。
