Bearings for rolling mills

Multirow Cylindrical Roller Bearings for Rolling Mill Plants

Multirow cylindrical roller bearings, specifically those with four and six rows, are used almost exclusively on the necks of the cylinders of rolling mills, calenders, and cylinder presses.

They have less friction compared to other cylindrical roller bearings and a high radial load capacity.

Being generally mounted with interference on the neck of the cylinder, they are particularly suitable for applications on rolling mills with high rolling speeds.

Their disassemblable construction facilitates installation, maintenance, and inspection operations.

The bearings allow, within certain limits, axial movements of the shaft relative to the housing.

Various configurations and customizable executions allow meeting the specific needs of each application, ensuring performance optimization.

Multirow Tapered Roller Bearings for Rolling Mill Plants

Ideal for the intense load conditions typical of rolling mill plants, four-row tapered roller bearings offer excellent capacity to withstand both radial and axial loads.

Their configuration increases the contact surface between the rollers and the tracks, allowing the bearing to effectively absorb combined loads.

This feature is important for applications that require high precision and reliability under extreme loads.

The bearings are designed to allow accurate adjustment of internal clearance, thus facilitating the optimization of performance based on specific operational conditions.

This functionality is particularly useful to adapt to thermal variations and dynamic loads of rolling mills.

Available in various configurations, such as “X” and “O” designs, these bearings adapt to a variety of operational needs, providing flexible solutions for different mounting configurations.

Bearings for Spindles

Designed specifically for spindle applications, these bearings represent a special variant of single-effect tapered roller thrust bearings.

Their ability to withstand extremely high axial loads makes them ideal for these applications, where strength and reliability are of primary importance.

A distinctive feature of these bearings is their ability to compensate for the angular movement of the spindle relative to the support to maintain optimal performance under various operating conditions.

This is made possible by the use of spherical races, which allow alignment movements without negatively impacting the bearing’s performance.

These bearings are equipped with races featuring threaded holes for lifting eyes, to simplify handling.
