ABSTRACT:
A ball bearing roller assembly for extensible draw tracks and the like includes a plastic roller having a bore with an annular race terminating at its rear end in a resilient releasable retainer lip and at proximate its forward end in a peripheral inside flange. A steel core coaxially registers with the roller and has a cylindrical outer race terminating at its forward end in a converging arcuate face and a coaxial stub projects rearwardly from the core. Bearing balls are entrapped between the races are impeded from forward movement and releasably restricted from rear movement by the resilient lip. A mounting plate includes a centrally apertured raised circular section abutting the core rear face with the stub engaging the aperture and being upset to lock the assembly and lock the balls against rearward release.
