Polyurethane on Aluminum

Medium duty kingpinless casters are superior due to the machined raceway that exerts radial force evenly where there is full contact between the ball bearing and the raceway. This greatly reduces wear on the raceway and eliminates the loosening forces of stress in the swivel section providing a smoother and stronger swiveling action. These raceways are built to last longer with less maintenance required and hold up better in high impact environments. Polyurethane on Aluminum Wheels are designed to roll easier and last longer than rubber on iron wheels. The polyurethane wheel tread is made out of high quality liquid cast polyurethane that is chemically bonded to the aluminum core to prevent any thread de-bonding. These wheels are very popular in applications such as Research Laboratories, Hospitals, Bakeries and many Industrial Manufacturing facilities.
