Polyurethane Caster Wheels with Iron Centers

Place of Origin:	Jiangsu

Polyurethane is superior to rubber in resistance to grease, oil, cutting, chunking, and abrasive wear. These caster wheels can be used on almost any dry factory floor. As with moldon rubber, the bonding agent which holds the polyurethane tire to its iron center can be affected by exposure to some chemicals, impact, overloading, and the buildup of heat. Tire hardness is 90 to 95 Durometer, Shore A. Temperature range is -20 to 180 F. The principle benefit of a polyurethane wheel over the same size rubber wheel is increased capacity. Given the same size load on a smooth floor, a polyurethane caster wheel rolls easier than the same size conventional rubber caster wheel. However, when used at full capacity, polyurethane is not easy rolling. Given a manual operation under ideal conditions, polyurethane caster wheels have a safe operating capacity of up to three times the capacity of the same size rubber wheel. Capacity ratings are offered as an idea of what the wheel will carry without failure. They are not absolute, but rather depend on the usage and service.
