4" x 2" Solid Polyurethane Elastomer Swivel Caster with Total Locking Brake - 1,000 Lbs Capacity

4" x 2" Solid Polyurethane Ball Bearing Swivel Caster with Total Locking Brake - Part #: 146HUBB420SBTL 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. * Total locking brake casters work best with softer wheels like neoprene, soft rubber, thermoplastic rubber & polyurethane. The softer wheel allows the brake pad to grip the tread effectively. While total locking brakes also work with harder wheels, a str
