Rolling Mill Bearing Manufacturers

When it comes to rolling mill bearings, you have many options. You can choose from Work roll bearings, Tapered roller bearings, Oil film bearings, or fibre bearings. These types of bearings are generally large in radial direction but comparatively small in axial direction. This design utilizes the available mounting space to support the radial forces.

Oil film bearings

Oil film bearings are a type of roller bearing that is designed for a rolling mill. This type of bearing is installed between the back-up rolls. The back-up rolls are subjected to rolling pressure, which requires a highly efficient oil film bearing system. These bearings are made from oil films that are hydrodynamic and hydrostatic, and are designed to operate at low energy consumption.

Rolling mill oil film bearings are made of stainless steel. They are manufactured at domestic rolling mills and are relatively large sliding bearings. Their key, also known as the long key, extends under the high pressure field of the oil film. As the key rotates, it deflects the sleeve, which creates a high variation in roll force. To overcome this problem, two shorter keys are installed on the shaft, outside the high-pressure zone. This design also allows the reusability of the old long-key rolls.

Fibre bearings

Rolling mill fibre bearings are one of the most common types of bearings for rolling mill applications. These bearings are composed of a plastic material called phenolic polymer. They are durable, heat resistant, and provide excellent load capacity. They also help reduce power consumption and lubricating oil costs.

The design of roll bearings for rolling mills is crucial in ensuring smooth rotation and minimizing power losses. They can accommodate high rolling loads and resist heavy shocks. They are easily interchangeable and provide stability during operation. They are a key component to rolling mills and are designed to withstand high temperatures and high speeds.
