Full-Complement (NCF)
The full-complement (NCF) single-row bearings include integral flanges on the inner and outer rings. These bearings also can manage axial loads in one direction and permit small axial
displacements.
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.
Double-row cylindrical roller bearings
Double-row cylindrical roller bearings are available in two types, NN and NNU, and two series, 30 and 49.The rollers in the NN type bearing are guided by the ribs of the inner ring. The rollers in the NNU typebearing are guided by the ribs of the outer ring.
Bearings are available with either a tapered bore type (which allows adjustment of radial internal clearance of bearing) or a standard cylindrical bore. The bearings come in two types, standard type and high-speed HS type. Standard cage is machined brass
