OVERVIEW: Heavy‐duty Needle roller bearings consist of a machined and ground channel‐shaped outer ring with a
component of needle rollers retained and guided by a cage. The high‐strength cage retains and guides the rollers. An
optional groove and hole in the outer ring facilitate relubrication. These bearings can be used with or without a machined or
ground inner ring, depending on the suitability of the shaft as a raceway surface.
APPLICATIONS: Gear pumps, sheaves, automotives transmissions and two‐cycle engines.
TYPES: With flanges ‐ NK/NKI/NKS/NKIS/NA48/RNA48/NA49/RNA49/NA69/RNA69, without flanges ‐ NAO/RNAO
1. MOUNTING DIMENSIONS
It is suggested that needle roller bearings are mounted in their housings with a clearance fit if the load is stationary relative
to the housing, or with a tight transition fit if the load rotates relative to the housing. Table 1 lists the suggested tolerances for the housing bore and the shaft raceway for metric series
bearings without inner rings. Table 2 lists the suggested shaft tolerances for the above two mounting conditions when the metric series bearings are used with inner rings. The
suggested housing bore tolerances for metric series bearings with inner rings is the same as the housing bore tolerance listed in Table 1 for metric series bearings without inner rings.
Table 3 lists the tolerances of metric series caged needle roller complement bore diameter for bearings without inner rings.
