<p>A roller-guided track apparatus includes a support member and a track roller arrangement. The track roller arrangement includes a roller and an axle having first and second axial ends. The first axial end of the axle is attached to the support member and the second axial end of the axle forms a distal end of the axle projecting away from the support member. The roller defines inner and outer sides of the roller and an aperture therethrough configured for receiving the axle. The roller is rotatable about the axle, with the inner side of the roller facing the support member. The distal end of the axle extends beyond the outer side of the roller and is orbitally deformed to form a head for retaining the roller upon the axle.</p> |
