Tires are mounted over Chair pads with machined O.D.’s. Precise clearances are maintained to allow for different rates of expansion between tire and shell.

Chair Pads are not welded to the shell, but are trapped in place by guide bars. Stop blocks are welded on one side only, alternating from one side to the other.

A loose Retainer ring is placed between the stop block and the tire. Wear takes place on the replaceable ring, not on the stop blocks.

Type of Tyre (Live ring Assemble):

1. Rectangular shape & steel cast / Forged with or without chamfer for thrust device .
2. Rectangular shape cast steel and with spline machined inner race teeth
3. Rectangular shape and steel cast / forged with drilled through-going holes for attachment of spline brackets

Tangential Suspension type Live Ring (It has zero Migration): Tangential suspension reduces ovality, forces on the shell are tangent rather than radial.

Brackets are bolted onto the tire. “Dog bones” keep the tire in position. Wedges keep the brackets tight against the dog bones. Springs keep the wedges tight as dimensions change with heat expansion.

The tire is fixed and does not creep inside the shell. Shell expansion is accommodated with a system of spring-loaded wedges.
