Abstract: The radial roller bearing has an outer ring (1), an inner ring (2), several roller members (3), and a cage (4). The cage (4) is guided on the edges (1a) of the outer ring (1) via several supporting rollers (5) distributed around the circumference in the form, for example, of ball bearings. This makes it possible to avoid sliding friction for guiding the cage (4) and to guide the cage without any clearance, so that the roller bearing can attain a high limit speed.

Abstract: A thread guide for guiding a thread between a bobbin of a warp or bobbin creel, from which the thread is payed-off, through a thread tensioner, while deflecting the thread through about 90.degree. in the direction towards a winding machine, is structured such that the thread, between its bobbin and upon leaving the creel, experiences a single deflection. This is accomplished by means of a deflection roll mounted to be low in friction and arranged at the outlet side of the thread from the bobbin creel. This deflection roll is arranged such that its axis extends vertically in a manner that the axis of the thread course, from the bobbin through the thread tensioner, up to the roll, forms a tangent at the traveling groove of the deflection roll. The deflection rolls which are operatively correlated with a vertical bobbin row at the creel are arranged in a tube or pipe. This tube consists of a number of tube sections, detachably interconnected with one another, while interposing in each case a deflection roll.
