Series 7000 - Cap. to 3,700 lbs.

#S-7008-PR Swivel

#R-7012-PR Rigid

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.
