Rolling Element Bearings
Rolling element bearings are used for the guidance of axles and shafts, whereby they absorb radial and/or axial forces and simultaneously allow the rotation of the shaft or of the mounted components. Thus the friction and power loss should be kept to a minimum. With the bearing power loss test rig of the FZG, the bearing losses under load or no-load can be measured
for various bearing arrangements. These results then can be used for the validation of the common calculation methods for the determination of the bearing losses. Taking bearing losses in the test rig into account, the resulting gearing losses can be determined.
Wear and frictional behaviour of bearings depend on the lubricant used. Evaluation of lubricant samples is possible on the rolling element bearings lubricant test rig FE-8, according to DIN 51819, for the determination of anti-wear capacity.
