Multi-Row cylindrical roller bearing has radial-load capacity and moderate thrust loads. It consists of a roller, which are cylindrically-shaped. These rollers are crowned or end-relieved to reduce stress concentrations. It is made of alloy steels or low-carbon steels. Its applications include mining, petroleum production, power generation, power transmission, cement processing, aggregate crushing and metal recycling. It is also used in rubber mixing equipment, rolling mills, rotary dryers and paper machinery.
