Abstract
A spindle for spinning or twisting machines comprises a rigid inner sleeve which contains a neck bearing and a step bearing for a rotatably supported shaft and which inner sleeve is accommodated in a bearing housing, the bearing housing being fixed to a spindle rail. The inner sleeve is supported against the bearing housing by two radially symmetrical acting metal springs. The spring rate of the metal spring which faces the neck bearing amounts to at least five times and at most twenty times the spring rate of the metal spring facing the step bearing. The ring space between the inner sleeve and the bearing housing is filled with a highly viscous fluid. The inner sleeve is closed off against the ring space with an oilproof seal.
