Polyolefin

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. Polyolefin wheels are a low cost when with high durability and resilience. Polyolefin wheels hold up great in wet environments since they have a high resistance to liquids, chemicals and greases. These wheels have a high abrasion resistance tolerance and are extraordinarily resistant to impacts and heavy shocks.
