Cylindrical Roller Bearings, Cylindrical Bearings in Delhi

The cylindrical roller bearings are the cylinders which can be used as rolling elements as opposed to balls in the ball bearings. The rollers have a great contact area with outer ring and distribute loads across an extensive surface. Subsequently, they have a relatively high radial load capacity and are suitable for high speeds. The double-row cylindrical roller bearings have a high radial rigidity and are primarily used for precision machine tools. By virtue of the line of contact between the rolling elements and raceways the cylindrical roller bearings have high radial load capacity and are suited for high-speed applications.

The cylindrical roller bearings from DCDC offer a complete range of both metric and inch sizes available. There are designated designs, special designs, bearings and cages that are available with pressed steel and polyamide throughout the range. The bearings are also available with lubrication holes and a machine lubrication groove on the outside surface and outer ring.
