A gas bearing roll shell assembly comprises an outer rotatable roll shell carried on an externally pressurized gas bearing between the roll shell and a stationary axle. The roll shell has end rings, one of which has turbine buckets recessed into its bore. The axle carries a valve body having part-chordal passages aligned with the turbine buckets and a rotatable valve for selectively driving the roll shell in one direction or the other. In a modified form, selection is limited to driving in a single direction by a pin and slot arrangement. The assembly is especially useful as an overrun roller in textile machinery involving the high speed transport of threads, yarns or the like.

A rear wheel bearing assembly has a double row of balls and a two piece inner race. One race piece is positioned on the other race piece to give a desired preload or end play and maintained in such position by a pair of semicircular hardened and ground keeper ring parts of selected width. The keeper ring parts engage the one race piece and are retained in a groove of the second race piece by a retainer ring secured to the second race piece by a swaging or rolling operation.

This energy absorber yieldably couples a bumper to support structure on a vehicle and comprises a spring bracket assembly which includes a pair of diverging spring arms which carry pins on the ends thereof. A preloaded yieldable energy absorbing band of resilient plastic material is stretched across the arms, by attachment to the spaced pins. On impact of the bumper, the pins are displaced outwardly from one another as the spring arms are deflected to stretch the energy absorbing band. The deflection of the spring arms and the stretching of the energy absorber absorbs impact energy.
