Opening roller for an open-end spinning arrangement

A spinning machine opening roller assembly comprising:

• a base body having only one radially outwardly facing centering guiding surface,
• a combing ring slidably mountable on said base body centering guiding surface,
• and a clamping member spaced from the base body and clampingly engageable with an end of said combing ring which is spaced from the centering guiding surface,
• whereby more than half of the axial length of the combing ring is unsupported along its inner circumference between the clamping member and the centering guiding surface.
