Heavy Duty Needle Roller Bearings NKI 5 / 12 Machined Race Single Row
Needle roller bearings
feature a small cross-section, higher load-carrying capacity, greater rigidity, and lower inertia forces that facilitate size and weight reductions in machinery. They're designed to withstand oscillation, perform under severe conditions, and interchange with sliding bearings.
Diverse types of needle roller bearings are available in a wide variety of sizes and tolerances, for a multitude of applications.
Some bearing designations for your reference:

Needle roller bearing:
1.Needle roller bearing is a cylindrical roller of roller bearings, relative to its diameter, roller is thin and long.This is called needle roller.Although has a small cross-section, bearing still has high load capacity.
2.Needle bearing with fine and long roller, so the radial structure is compact, its diameter and load capacity at the same time, with other types of bearing outside diameter to a minimum, especially suitable for the limited size of the radial installation supporting results.
3.In order to ensure the load capacity and operation performance
and you have the same ring bearing, axis or shell hole hardness on
the surface of the raceway, machining accuracy and surface quality
should be as a bearing ring raceway.
