Product Details

NA49 Series Precision Needle Roller Bearings With Inner Ring

Machined Needle Roller Bearings are bearings with a low sectional height and large load ratings. The outer ring has high rigidity and can easily be used even for light alloy housings. These bearings are available in metric series and inch series, both of which have the caged type and the full complement type. It is therefore possible to select a suitable bearing for use under various conditions such as heavy loads and high-speed or low-speed rotations. In addition, there are bearings with and without an inner ring. As the type without inner ring uses a shaft as the raceway surface, a compact design is possible.

Design Attributes

High-strength cage retains and guides rollers

High speed and lubrication-retention capability.  A lubrication groove and hole in the O.D. facilitate relubrication through the outer ring.

Bearings can be used with or without a machined and ground inner ring depending on the suitability of the shaft as a raceway surface.

Applications

Gear pumps

Sheaves

Automotive transmissions

Two-cycle engines
