ABSTRACT:
According to the invention, an inexpensive antifriction bearing is located in a plastic block and the plastic block is encircled by a further plastic ring. The softening point of the plastic ring is lower by 20.degree. C. than that of the material of the bearing block and between the softening point and melting point of the ring a difference of at least 30.degree. C. exists ensuring that in case of excessive warming up of the bearing, the sliding on each other of the plastic block and of the outer plastic ring as plain bearing, puts the bearing out of action for a certain time. The contact surfaces of the bearing block and the ring are spherical, ensuring the compensation of possible eccentricity by self-aligning. The ring is fixed in the seat of a roller by flanging. The invention renders superfluous the otherwise indispensable high-precision single-purpose machine or horizontal lathe for boring the roller, and makes possible the application of the technology of mass production.
