ABSTRACT:
A supporting disk for a supporting disk bearing of open-end spinning rotors comprises a disk-like metal base body and a thin running ring made of plastic. The outer diameter of the running ring measures at least 75 mm. The width of the running ring amounts to at most a tenth of its outer diameter. With these dimensions, the supporting disk can withstand the heat load at rotor speeds of over 130,000 rpm, so that often so-called cooling grooves and anchoring grooves can be omitted.
