INA NK 80 mm Needle Roller Bearing (Without Inner Ring)

The INA NK series is a specialized needle roller bearing engineered for applications requiring maximum radial load capacity within minimal axial space. This specific 80 mm model features a design without an inner ring, allowing it to be mounted directly onto a hardened shaft. This configuration eliminates the need for a separate inner race, resulting in a thinner overall cross-section that is ideal for tight installation envelopes.

Technical Features & Benefits

• High Radial Load Capacity: The use of needle rollers (thin cylindrical rolling elements) enables the bearing to absorb significant radial forces while maintaining a compact height.
• Space-Saving Design: The absence of an inner ring reduces the overall diameter, making it suitable for machinery with limited clearance around the shaft.
• Direct Shaft Mounting: Designed to run directly on a precision-ground and hardened shaft, ensuring optimal fit and load distribution.
• German Engineering: Manufactured by INA (a leading brand in rolling bearings), ensuring high quality, durability, and consistent performance standards.

Applications

This bearing is commonly used in automotive components, industrial gearboxes, agricultural machinery, and construction equipment where high radial loads are present but space is at a premium.
