Esco’s Hot Wheel heat indicator label, attached to a wheel or rim by self-adhesives, is designed to warn drivers, maintenance personnel and safety inspectors of possible wheel end, bearing and brake failure during walkaround inspections. When the temperature of the wheel reaches 250 degrees Fahrenheit, the temperature-sensitive white arrow changes and remains bright orange, warning of an overheated wheel condition.
After the wheel problem has been corrected, a new Hot Wheel decal must be installed. Although the decal is not designed to indicate all instances of a possible wheel end component malfunction, it will indicate excess temperature for prolonged periods that could cause decreased function or failure.
