A two-piece longitudinally adjustable roller skate has a pair of support axles resiliently mounted to it. Each axis is mounted for pivotal movement about a transverse axis. The axes are downwardly converging about the middle of the skate so that pressure to one side or the other will cause the inner ends of the axles to move together, thus causing automatic turning of the skate. Each axle mounts a pair of spherical wheels. Each wheel includes an internal bearing having a single inner and a single outer race formed within the wheel. Each axle extends through an axle carrier which mounts the axle and the pair of wheels is mounted on the ends of an axle which extend out of the associated axle carrier. The bearings in the wheels abut the axle carrier and are held in place by nuts attached to the axle ends.
