Abstract

A rotating band of projectiles is made of a compound sleeve bearing material. The compound material comprises a carrier material and a porous slide layer applied thereto and having pores filled with a polytetrafluoroethylene mixture. The outer surface of the slide layer is coated with a cover layer of a polytetrafluoroethylene mixture. The rotating band is held in place in the groove by a latching connection.
