SPRING WASHER AND A BEARING BLOCK INCLUDING A SPRING WASHER

---

Abstract

---

A spring washer is disclosed for axially preloading anti-friction bearings. The spring washer can include an outer ring and an inner ring that is coaxially arranged with respect to the outer ring. An axis is defined by the two rings. Outer and inner rings are connected through several resilient connection rods. Resilient cantilevered rods can be provided which extend from one of the rings in between the connection rods and which have a free end at the opposite positioned ring. Thereby, the cantilevered rods can be axially bent up such that the free end has an axial offset.
