TWO-ROW BEARINGS
Two-row, or double-row, cylindrical bearings offer added radial capacity over tradition one-row types. These bearing types are interchangeable so the dimensions and diameter under the rollers (NNU style) and diameter over the rollers (NN style) are held to an ISO/DIN standard. The standard cage design is a drilled pocket, finger-style retainer
FOUR-ROW BEARINGS
Four-row cylindrical bearings have an extremely high radial load capacity, but no thrust capacity. This bearing type is mostly used in roll neck and work roll applications in the metal rolling industry. Straight and tapered bore designs are available.
In a cylindrical roller bearing, the rollers and racewaysare in linear contact. Consequently this type of bearing can support a larger radial load than a point-contact ball bearing. Also, its structure is suitable for high-speed operation.
A cylindrical roller bearing used for the main spindle of a machine tool can have either a double- or singlerow configuration, and certain variants have a tapered bore so the radial internal clearance can be adjusted.
