 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.

cylindrical roller bearings effectively reduce friction and
help transmit power in applications like:
• Power generation
• Oil fields
• Crop shears
• Gear drives
• Hoists
• Metals construction
• Mining
• Aggregate processing
• Pumps
• Rolling mills
• Wheel-end planetaries
• Wind energy
• Other industrial equipment
