Cylindrical roller bearings consist of an inner and outer ring, a roller-retaining cage, and a complement of controlledcontour cylindrical rollers. Depending on the type of bearing, either the inner or the outer ring has two roller-guiding ribs. The other ring is separable from the assembly and has one rib or none. The ring with two ribs axially locates the position of the roller assembly. The ground diameters of these ribs may be used to support the roller cage. One of the ribs may be used to carry light thrust loads when an opposing rib is provided.The decision as to which ring should be double ribbed is normally
determined by considering assembly and mounting procedures in the application.

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.

 

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
