|  | | Hamilton Cush-N-Aires have become widely recognized as the leading pneumatic-tired casters in the industry. The quality that earned this reputation continues without compromise: all swivels are S.A.E. 1045 drop forged steel with an integrally forged kingpin and precision tapered thrust bearing to ensure easy swiveling and longer life.
| These shock absorbing casters are popular for handling missile components, electronic equipment, ceramics, liquids, etc., as well as for use outdoors over rough surfaces. Pneumatic tires offer -variable flotation-: reduce inflation pressure to improve cushioning for lighter loads, or inflate fully for optimum rollability and capacity loads. All wheels except the 4-ply 16" size have bolted hubs.
| Rigid Cush-N-Aire models, offering overall height and template patterns to match the swivels, are constructed of plate steel legs welded inside and outside to steel mounting plate.
