Double-row cylindrical roller bearings. Double-row cylindrical roller bearings come in two types: with a cylindrical or a tapered bore. As for those with a tapered bore, the specified amount of clearance can be obtained by adjusting the press-in distance. Some bearings are fitted with lubrication holes and lubrication grooves on the outer ring.
Four-row cylindrical roller bearings are used almost exclusively for the roll necks of rolling mill stands, calenders and roller presses. Because they are normally mounted with an interference fit on the roll neck, four-row cylindrical roller bearings are well suited for rolling mill applications where the rolling speed is high.

Tapered roller bearings, cylindrical bearings, and combination bearings support axial and radial loads, such as those encountered on vehicle axels where there force is both through the wheel and along the wheel axis. Needle roller bearings support high speed, high radial loads in confined spaces.

RBEC ratings describe the accuracy and tolerance range of different types of bearings. As a rule, the higher the RBEC number, the tighter the bearing tolerances. Typically, cylindrical roller bearings are lubricated with oil, which also serves as a coolant. Most cylindrical roller bearings are made of alloy or low-carbon steels.
This type of geometry allows the rolling element to support larger loads than ball bearings. Cylindrical roller bearings have a high radial load capacity because the rollers and raceway are in linear contact, and they are suitable for applications that provide heavy radial and impact loads.
Koyo offers a full range of spherical roller bearings for the steel industry, in addition to radial and angular contact ball including precision machine tool bearings, and cylindrical roller bearings. Click here for a video of Koyo Bearings' capabilities
