The Fein 30905034008 cup spring is a genuine replacement component for selected Fein high-frequency die grinders and angle grinders. Also known as a disc spring or Belleville spring, it is used within the machine's mechanical assembly to provide spring tension and replace a worn or damaged original component.
Compatible models include Fein MShyo840-1, MShyo840-1b, MSho849-1z and MShyo848-1z die grinders, along with MSfo849-1b and MSfo849-1c angle grinders.
Some machine assemblies require two cup springs. This product is supplied individually. Check your machine's full 11-digit model number before ordering.
