ABSTRACT:
An adjustable roller bearing for lateral guidance of travelling webs, e.g. a paper wire, comprises a bearing casing that is slidably mounted in a bearing foundation by the aid of members projecting diametrically from the bearing casing and bearing foundation and being in engagement with each other as well as encased by in hydraulic or pneumatic bellows which act to displace the bearing casing. The projecting members are provided with cooperating guide grooves and rollers respectively. The guide grooves are diametrically outside the contact faces of their associated roller, and have faces which in cross section follow a circular curve having the roller center as its center. Between each of these faces and the adjacent roller contact face there is a lining one end of which is adapted to the circular shape, whereas the other side, facing the roller contact face, is planar and forms a contact face for the corresponding roller.
