Resumo

SKF is long acquainted with the use of rolling bearings in rolling mills. As early as 1922 SKF introduced roller bearings as roll neck bearings in its Hofors Bruk steel mill in Sweden. Since then both, builders and operators of rolling mills have benefited from innovative SKF bearing technology. SKF four-row tapered roller bearings are available in different designs and a wide range of sizes appropriate to the application. These include: TQO and TQI configuration (face-to-face or back-to-back arrangement); Sealed and open bearings; Bearings with and without extended inner rings; Bearings with a cylindrical and tapered bore; Bearings with and without spacer rings. Features of these SKF bearings include: Logarithmic contact profile between rollers and raceways provides a more favorable stress distribution in the bearing and considerably enhances operational reliability; Special roller end/flange contact geometry designed to promote lubrication and minimize friction.
