NSK Hot Rolling Mill Bearings

NSK's high-capacity bearings are used for various types of machinery. Besides, the company also produces Gun metal bearings, Slewing ring bearings, and Tapered roller bearings. You can read about these products in this article. It will also help you learn more about their benefits and uses.

NSK's high capacity bearings

NSK's high capacity hot rolling mill (HRM) bearings are designed to provide outstanding reliability and durability in high-speed applications. They're made to withstand high heat and heavy loads, and can handle fast accelerations and variable speeds. Furthermore, they're engineered to run at the highest accuracy, which is essential for achieving high precision in rolled steel.

Tapered roller bearings

Axial bearings are used primarily in heavy mills in which considerable axial forces are experienced. They are usually made up of two rows of tapered rollers that intersect at one point on their centerlines. These rollers receive loads from the surface of the inner ring and the outer ring raceways.

Slewing ring bearings

Slewing ring bearings have a unique design that meets the demands of various industries. They must withstand massive loads, have a limited range of rotation, and maintain repeatability of motion. Furthermore, they must have long service lives. These characteristics make NSK slewing ring bearings ideal for transferring high forces. They can support radial, axial, and moment loads. The bearings are also available with lubrication features that facilitate grease replenishment.

Gun metal bearings

Slider bearings with metallic bush are also known as gun metal bearings. They have good bearing properties but low life and are generally used in low-capacity rolling mills. They are cheaper, have low co-efficient of friction, and are easy to machine. They also offer good corrosion resistance. They typically contain 85 percent copper and 5 percent tin or lead.

Sealed Clean seals

Sealed Clean seals for hot rolling mills feature multiple components that work together to protect hot rolling mill bearings from contamination. These components include a synthetic rubber neck seal, an inner and outer seal ring, and an end plate. These components are designed to minimize the inertia of the seal and are corrosion-resistant. A flexible neck seal allows for ease of installation and removal without disassembling the bearing.

Precision requirement

Hot rolling mills are demanding environments that place high demands on the precision of bearings. These bearings must withstand the high temperatures, heavy loads, and rapid accelerations of this process. Precision is required to ensure high-quality rolled steel. NSK offers a variety of bearing solutions to meet the demanding requirements of these hot rolling mills.
