Super precision angular contact ball bearing for high rotational speed
ID: 6 - 120 mm | 719-70 E design SKF

The new SKF super-precision bearings in the 719 .. E (VEB) and 70 .. E (VEX) series are designed for very high operational speeds. They're characterized by high degree of stiffness, relatively high load carrying capacity, extended bearing service life, low heat generation and compact cross section. Compared to high-speed B design bearings, high-speed E design bearings have a higher speed capability and they can accommodate
heavier loads.

Bearings in the 719 .. E (VEB) and 70 .. E (VEX) series provide high reliability and superior accuracy for applications such as high-speed machining centres, milling machines, internal grinding machines and
woodworking machines.

They are available in an extended range as follows:
- 719 .. E (VEB) series: open bearings accommodate shaft diameters ranging
from 8 to 120 mm; sealed bearings from 20 to 120 mm.
- 70 .. E (VEX) series: open bearings accommodate shaft diameters ranging
from 6 to 120 mm; sealed bearings from 10 to 120 mm.

Bearings in both series are manufactured to two tolerance classes (P4A or PA9A) and are available with three contact angles (15° and 25° as standard, 18° on request), two ball materials (steel or ceramic) and two ring materials (steel or NitroMax steel).
Those suitable for universal matching or mounting in sets are produced to
various preload classes, to meet almost all application requirements in terms of speed and rigidity (light preload, moderate preload, heavy preload in applications where a maximum degree of rigidity is required; reduced light/moderate or heavy preload in applications where maximum operational speeds are required).
Bearing variants for direct oil lubrication are available.
