描述
特点:轴向/径向轴承YRT
YRT轴承由一个推力/向心座圈,一个推力/向心轴圈,一个推力垫圈,两个滚针保持架组件和一组向心圆柱滚子组成。座圈和轴圈有均布的安装用螺钉孔。该型轴承具有高轴向和径向承载能力。高倾斜刚度和极高的精度。适用于回转工作台,卡盘和铣刀头以及测量和实验中的轴承配置。该型轴承对与之相配的设备零件的要求也较高。安装时需控制安装螺钉的扭紧力矩。
轴承特点:
1、高精度:精度可达到P4、P2级;
2、高刚性:该系列轴承均带有预载荷;
3、高承载:可承受轴向载荷、径向载荷、倾覆载荷。
4、高转速:YRTS系列轴承可应用于转速较高的工作场合。
适用范围:被广泛应用于精密回转台立式磨床、分度头、滚齿机、铣齿机工件轴等精密装置。
