is designed specially for drive chains of twin-wheel
transportation facilitiess;
is intended both for standard, and for circuits such as About -
ring (with rings of round section);
is chemically inert to elastomeric members of circuits such as
O-ring;
the speed key of fissile components promotes formation of a
protecting film on each chain link, which one differs by high strength,
stability and stability in conditions of high pressures and
temperatures;
the elastomeric members protect circuits from loss of elasticity,
clay swelling and bending.
