A mounting plate (20, 120) for a linear skate upon which a plurality of wheel supporting brackets (22, 24, 26 & 28) are affixed in an equally spaced, generally aligned relationship. A wheel-receiving axle (32, 34, 36 & 38) is secured in each bracket, with each axle intended to receive thereon a closely fitting skate wheel (12, 14, 16 & 18). Each axle has a novel, expansion-producing arrangement (52, 62) enabling the outer end of the axle to be enlarged so as to tightly engage the non-rotatable inner portion (80) of a respective skate wheel. Each wheel is thus retained on its respective axle in a fully operational manner, without fear of the wheel coming off the end of the axle. The mounting plate has raised shoulders (84 & 86; 126 & 128) along each long side, serving not only to prevent undesired bending or twisting, but also serving to prevent the several wheel- supporting brackets from twisting out of a desired relationship to the mounting plate.
