4" x 2" Solid Polyurethane Elastomer Wheel Kingpinless Swivel Caster - 1,000 Lbs Capacity

4" x 2" Solid Polyurethane Elastomer Wheel Kingpinless Swivel Caster - Part #: P5104201631 Solid cast polyurethane elastomer wheels are similar to solid poly wheels but offer higher capacities, have excellent impact strength, abrasion resistance & compression resistance. The polyurethane elastomer tread is mechanically locked to a glass filled nylon core which greatly decreases the chance of tread de-bonding failures. They are easy to start rolling & offer a smooth ride. These wheels are 100% washable, steam cleanable & chemical resistant. These wheels are often used in places poly on metal core wheels cannot be used or if more capacity & durability is needed compared to the other polyurethane wheels. * Our kingpinless swivel caster rigs outlast traditional kingpin designs by preventing stretch-induced plate & fork separation. Providing more durability & more capacity (depending on the wheel) while reducing downtime and replacements.
