PRECISION, PERFORMANCE AND EXTENDED BEARING LIFE IN COLD ROLLING
In cold rolling, the performance of the equipment is closely linked to the precision and condition of its most critical components. This is particularly true in demanding Sendzimir mill applications, where consistency over time is essential to maintaining the required quality standards. Faro Bearings combines specialised manufacturing expertise with dedicated reconditioning services to support the performance and service life of backup bearings in steel production.
Backup Bearings for Sendzimir-Type Cold Rolling Mills
Sendzimir cold rolling mills, thanks to their compact and robust structure, are capable of producing significant reductions in strip section at high speeds and under high pressures. The processed product must comply with very tight tolerances on thickness, flatness and surface finish. These requirements can only be met if the backup bearings rotate with an extremely high degree of precision. set of bearings, restoring the geometric parameters of the original backup roll.
The quality of Faro Bearings backup rolls is guaranteed above all by the use of high-purity steels, subsequently hardened following a new procedure that makes it possible to obtain optimal mechanical characteristics, as well as by high precision machining and sophisticated measurement methods. They are manufactured with tight tolerances and have a rotation accuracy better than P4. These characteristics ensure the highest quality of the rolled product in terms of surface finish and flatness.
Reconditioning of Backup Bearings
Faro Bearings’ decades-long experience, gained through collaboration with numerous customers, has made itpossible to establish proven processes for restoring backup bearings. In this way, it is possible to significantly extend the life of each bearing, resulting in economic savings. Reconditioning makes it possible to restore a bearing to an “as-new” condition, allowing substantial savings and contributing to maintaining production at consistent levels of profitability. It should also be emphasized that the time required for repair is significantly shorter than that required to manufacture new products.
This reconditioning process also contributes to environmental sustainability, limiting the need to produce new components and, consequently, reducing the ecological footprint associated with the manufacture and disposal of bearings. Bearing reconditioning is therefore an important service for the steel industry, as it not only allows cost savings and improves parts availability, but also reduces the risk of failures and the resulting downtime.
