You should never select on the basis of load capacity alone. Capacity ratings do not take into account the effort required to manually move a load. Capacity ratings are based on manual operation under ideal conditions. If these wheels are going to be moved by mechanically powered equipment, consult us for a reduced capacity rating based on your application.
The blue tire (tread) on the Road Case Caster wheel is a flexible elastomer. What makes this elastomer special is its ability to bounce. Resilience in a wheel material is a necessary feature in order to protect the cargo being moved. The tire on this wheel is a resilient synthetic elastic rubber. It provides the performance of a cushion ride without the expense associated with a tire made using natural rubber. The tire is chemically bonded to a heavy duty impact resistant industrial grade polyolefin core (center).
The Road Case Caster wheel got its name because it was specifically designed to withstand the kind of conditions road cases are typically exposed to. It will roll over cords, thresholds, up and down ramps, over uneven surfaces such as asphalt and truck ramps, and other obstructions. This wheel is also great for other applications such as to move lighting fixtures, computers, and audio visual equipment. It is the 4″ diameter wheel of choice for many applications in Scientific and Electronic Laboratories, TV and Movie Studios, Hospitals, Hotels, and Department Stores. The Road Case Caster wheel is ideally suited to move fragile or delicate cargo, and wherever noise and vibration should be reduced.
We install the Road Case Caster wheel in zinc plated corrosion resistant steel caster frames with a choice of 3 different mounting plate sizes. The swivel caster frames shown with a metric mounting plate have a seal on the swivel bearing. The other caster frames have the swivel protected by a metal cover. The swivel section under the mounting plates consist of two rows of ball bearings for easy rotation. Two types of brakes are optional. The Total Lock brake locks the swivel and the wheel simultaneously. The casters with the brake pedal on the side of the wheel lock only the wheel.
The Road Case Caster wheel comes only in a 4″ diameter. If you need a 5″ or 6″ or 8″ diameter wheel with the same performance characteristics as the Road Case Caster wheel check out our Blue Ergonomic Rubber Caster Wheels.
