NA69 Double Row Needle Bearings With Inner Ring
Needle bearings feature a smaller 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 bearings are available in a wide variety of sizes and tolerances, for a multitude of applications.
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
