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. Polyflexon wheels are specifically designed to provide a balance between durability, load capacity, and flexibility. These wheels are made from high-quality polyurethane materials, which offer excellent resistance to wear, tear, and impact. They are suitable for a wide range of applications, including industrial carts, dollies, medical equipment, and various material handling equipment.
