Abstract

For a dual-mass flywheel in the driving train of a motor vehicle there is proposed a cage-free ball-bearing 9 which has solid balls and is therefore particularly narrow in the axial direction and is sealed in a lubricant-tight manner by a sealing and insulating ring arrangement 31 formed by two ring elements 27, 29. The ring elements 27, 29 are tightly connected to one another axially beyond the ball-bearing 9 and rest with inherent elasticity under bias on the lateral faces of the ball-bearing 9.
