The support and guide roller is for use in draw guides and similar devices formed from a cylindrical core body of high strength. It has a central aperture to accommodate a bearing cap with an anchorage profile on the cylinder jacket for mounting a plastic jacket of lower strength. It is constructed such that the anchorage profile (3, 4, 5) of the core body (2) has sequentially arranged positive and negative radii of curvature (7, 8). The anchorage profile (3, 4, 5) has its smallest separation from the central hole (13) at the core body (2) front surface. |
