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。
