Rotary Kiln Tyres, sometimes called riding rings, usually consist of a single annular steel casting, machined to a smooth cylindrical surface, Rotary Kiln attach loosely to the Rotary Kiln shell through a variety of "chair" arrangements. These require some ingenuity of Rotary Kiln design, since the tyres must fit the Rotary Kiln shell snugly, and also allow thermal movement. The Rotary Kiln tyres ride on pairs of steel rollers, also machined to a smooth cylindrical surface, and set about half a Rotary Kiln-diameter apart. The rollers must support the Rotary Kiln, and allow rotation that is as nearly frictionless as possible.

A well-engineered Rotary Kiln, when the power is cut off, will swing pendulum-like many times before coming to rest. The mass of a typical 6 x 60 m Rotary Kiln, including refractories and feed, is around 1100 tonnes, and would be carried on three Rotary Kiln tyres and sets of rollers, spaced along the length of the Rotary Kiln. The longest Rotary Kiln may have 8 sets of rollers, while very short Rotary Kiln may have only two.Rotary Kiln usually rotate at 0.5 to 2 rpm, but sometimes as fast as 5 rpm. The Rotary Kiln of most modern cement plants are running at 4 to 5 rpm. The bearings of the Rotary Kiln rollers must be capable of withstanding the large static and live loads involved, and must be carefully protected from the heat of the Rotary Kiln and the ingress of dust. In addition to support rollers, there are usually upper and lower "retaining Rotary Kiln rollers" bearing against the side of tyres, that prevent the Rotary Kiln from slipping off the support rollers.
