FV BEARING-rolling mill bearings - FV BEARING INDUSTRIES

The bearing consists of smooth rollers or metal balls and smooth inner and outer surfaces (called raceways) on which the rollers or balls roll. These rollers or balls act as a load carrier for the device, allowing it to rotate freely. Bearings usually encounter two kinds of loads: radial load and axial load. Radial loads occur perpendicular to
