Kingpinless caster design - no swivel kingpin to bend or break. Better than standard casters at withstanding shock and impact. Last longer, saves money.
Series 93-94 casters are made from forged steel. Top plate and inner raceway are forged from one piece, providing a superior raceway construction for shock conditions. This forged design outperforms the standard steel plate welded to tubular steel inner races, especially in abusive and impact-loading conditions.
