The greatest challenges for the roller bearings are the high speeds and dynamic loads in the wire rod blocks. With a rolling speed of up to 120 m/s and sudden peak loads during the initial pass, the roller bearings are subjected to extremely high forces. Depending on the form and temperature of the rolling stock, these initial peak loads may be more than twice the rolling force or mill torque. These considerable stresses reduce the service life of roller bearings significantly. Only stable, high-precision special bearings can accommodate the loads generated and enable long-term operation of the plant – just like SMS group‘s high-precision roller bearings, which have a DIN 620-compliant accuracy standard of P5 – P2 in respect of their parallelism and running accuracy.
