INA NK 29 mm Needle Roller Bearing (Without Inner Ring)

The INA NK 29 mm Needle Roller Bearing is a precision-engineered component designed for applications requiring high radial load capacity within limited axial space. As a "needle" bearing, it utilizes thin, cylindrical rollers that maximize the contact area between the rolling elements and the raceway, allowing it to withstand significant radial forces despite its compact profile.

Key Features & Design

• No Inner Ring Design: The NK series lacks an inner ring, allowing the bearing to be mounted directly onto a hardened, ground shaft. This design choice significantly reduces the overall radial height, making it ideal for space-constrained assemblies.
• High Radial Load Capacity: The multiple needle rollers distribute the load evenly, providing excellent stability and durability under heavy mechanical stress.
• Compact Footprint: The slender profile of the needle rollers ensures a minimal radial dimension, optimizing the layout of the machinery.

Applications

This bearing is widely used in automotive transmissions, industrial machinery, agricultural equipment, and robotics where compactness and high load-bearing capability are critical. It is particularly suitable for shafts that are ground and hardened to serve as the inner raceway.
