Ball bearing bearing E series

angular-contacthigh-speed

E design bearings (fig. 1), when compared to D design bearings, have a more open osculation and a maximum number of smaller balls. They can therefore accommodate very high speeds but do not have the same high load carrying capacity as D design bearings. Compared to B design bearings, E design bearings have a slightly higher speed capability and can accommodate heavier loads. Applications Typical applications for bearings in the 719 .. E and 70 .. E series include: electro-spindles (fig. 2) high-speed machining centres (horizontal and vertical) (fig. 3) high-speed milling machines high-speed internal grinding machines (fig. 4) high-speed spindles for PCB drilling woodworking machines
