A Guide to Back Up Roller Bearings

A back up roller is a bearing in a machine that supports sheet metal during rolling. The quality of the rolled sheet metal depends on the bending rigidity of the support shaft, section height tolerance and running accuracy. The back up roller has special characteristics to ensure that the rolled sheet is flat and has a high surface quality. It is made of rolling bearing steel and is usually sealed with a lamellar ring. This means that the bearing requires minimal lubrication.

LYSYM

LYSYM back up roller bearings feature an advanced axial containment system and cylindrical roller cage. They are designed to ensure high efficiency over their lifetime and can operate in high temperatures. A lubrication circuit is built inside the bearing to ensure smooth operation and low friction. They are available in both radial and axial-radial versions. LYSYM also offers a range of seals in both synthetic and metal materials to provide maximum protection against wear and tear.

LYSYM back up roller bearings are widely used in various industries including special and general machinery. They are designed to meet the requirements of different industries and can also be customized according to customer specifications.

NEWORLD

Cylindrical roller backing bearings are the most common type of backing bearings and NEWORLD offers many different designs. There are needle roller bearings and double row tapered roller bearings. These bearings feature a logarithmic contact profile, which results in improved stress distribution under any load condition. They also have an optimised finish, which improves lubrication conditions. They typically have lubrication holes in the outer ring and integral flanges in the inner ring.

Back up roller bearings are important for rotating machinery, which needs to perform reliably and efficiently. With these bearings, you won't have to worry about failures due to damage. They offer superior performance, and last longer than most other bearings.

UMBRAGROUP

UMBRAGROUP has improved its back up roller bearing technology for the rolling mill industry. Founded in Foligno, Italy, the company was acquired by Thomson Aerospace & Defense in 2013. Now, the company has an office and manufacturing facility in Foligno, just across the river from downtown Foligno.

The company is a global leader in the production of high-tech components. Its headquarters are located in Foligno, Italy, and it also has additional production sites in Germany and the US. Its products include ball screws, sector gears, pinions, tie rods, and gimbals.

EVERGLORY

The EVERGLORY back up roller bearing features high precision and end face height, and can accommodate a large radial load. Its high T value is necessary for applications involving high radial load, such as multi-roll cold rolling mills. Its precision grade is higher than P4, and its end face height is controlled within 0.005mm. Its T value can withstand a high radial load, and it is suited for high-speed operation.

NSK

NSK back up roller bearings are engineered for extreme operating environments. Featuring a wide variety of materials, these back-up roller bearings are ideal for demanding applications. With a cage made from mould steel, bronze, or cast steel, these back-up roller bearings provide high load capacity. To maximize efficiency and reliability, NSK offers a variety of optional upgrades for these high-performance bearings.

These back-up bearings are designed to handle heavy loads and to run with excellent rotational accuracy. In cluster mills, high rotational accuracy is crucial to maintain the dimensional quality of the final product. NSK's back-up roller bearings for cluster mills are engineered for high ring strength and exceptional running accuracy. They offer long-life service life and help reduce maintenance costs. Additionally, they help reduce CO2 emissions and material consumption.
