Supreme Rubber Caster Wheels
Supreme Rubber material is much higher quality compared to a standard rubber wheels material. The tensile strength is much higher from a range of 1200 to 1400 tensile strength. These wheels offer a very shock absorbing semi-cushioned ride, rolls easily over small debris, rough floors, cracks, and joints. Great floor protection and a very quiet rolling operation. These wheels work great in outdoor environments as the aluminum core will not rust like your standard mold on rubber wheels which usually contain a cast iron core. All Black Rubber wheels can mark the floor as they contain black carbon. Marking floors will only occur if the swivel casters have no free range of motion and can not swivel properly. If the casters can swivel properly and not become dragged these wheels do not end up marking floors or leaving streaks. These are considered the highest quality rubber caster wheels on the market when comparing different types of Rubber Wheels for Casters.
