4" x 1-1/2" Polyurethane on Polyolefin Core Wheel - 400 Lbs Capacity

4" x 1-1/2" Polyurethane on Polyolefin Wheel - Part # LPPU415 These Polyurethane on Polyolefin wheels are a fantastic wheel and going to be the most economically priced of the polyurethane wheels. They will work great for most general industrial applications, however, for applications that require higher capacities we recommend our polyurethane on iron wheels. Polyurethane on polyolefin wheels offer more floor protection, non-marking treads, quieter rolling, & smoother rides compared to steel or phenolic wheels while still providing comparable load capacities. These wheels can be used in most applications, but are not recommended for hot or cold applications, or when left in direct sunlight for most of their use. Because we have a wide range of bearing sizes and types available, we only have our most popular bearings listed in the options. If you don't see the bearings or hub length you are looking for, please contact us for help.  Specifications: Wheel Diameter: 4" Hub Length
