High-precision cylindrical roller bearings are seen by IBC as the right choice if the bearing has to be suitable for high rotational speeds, minimal frictional loss, high radial loads and heat-induced changes in length in the adjacent parts. As the German company explains, cylindrical roller bearings equipped with a cage can bear very high loads in the radial direction, and due to line contact between the roller and the raceway, they also have the advantage of great stiffness. They are also designed for high rotational speeds. The range of bearings designed for general mechanical engineering includes both single- and double-row cylindrical roller bearings with cage and full-complement cylindrical roller bearings. The former can reportedly achieve reasonably high rotational speeds even under heavy loads. The latter, on the other hand, are designed for low rotational speeds and pivoting. This type of bearing can bear very heavy radial loads since it contains the greatest possible number of rolling elements and has great stiffness. These full complement cylindrical roller bearings are often chosen in space-saving designs and used in slow-rotating bearing applications that are heavily loaded.
Heavy-duty and high-precision cylindrical roller bearings
IBC manufactures cylindrical roller bearings in various designs, dimensional series and sizes. Their ability to tolerate axial shifts reportedly predestines them use as floating bearings for work spindles in machine tools.
