Abstract
NOVELTY - The spindle has a first spindle bearing set (10, 12) for high revs. and low axial loads and a second set (14) for low revs. and high axial loads. These can be brought into engagement to receive axial loads by means of a setting device (16, 24). The bearing sets may be in a common casing (4, 6, 8), with the second one able to move in the casing against a preset force relative to the spindle. USE - For taking high axial forces and running at high revolutions. ADVANTAGE - Stronger construction to withstand forces arising in deforming processes.
