The roller is characterized in that the elastomeric material is formed into inner and outer concentric cylinders which are joined together and which encompass therebetween in co-axial relation a rigid cylindrical bushing. Preferably, the inner and outer cylinders are connected by bridges defined by holes formed in the bushing. The bushing may include beveled end faces for facilitating centering of the bushing in a mold.
