INA NK 37 mm Needle Roller Bearing Without Inner Ring

The INA NK series is a high-performance needle roller bearing engineered in Germany for industrial machinery and construction equipment. This specific model features a 37 mm bore and is designed without an inner ring, allowing it to be mounted directly onto a hardened shaft. This design maximizes radial load capacity while minimizing the overall width of the bearing unit, making it ideal for applications where space is limited.

Key Features & Benefits

• High Radial Load Capacity: The needle rollers provide a large contact area, enabling the bearing to absorb significant radial forces efficiently.
• Space-Saving Design: The absence of an inner ring reduces the overall width, facilitating installation in tight mechanical spaces.
• Direct Shaft Mounting: Designed to fit directly on the shaft, which must be ground and hardened to ensure proper fit and durability.
• German Precision: Manufactured by INA, a leading global provider of rolling bearings, ensuring consistent quality and reliability.

Applications

This bearing is commonly used in agricultural machinery, construction equipment, conveyor systems, and industrial drives where high radial loads are present and axial space is restricted. It is a critical spare part for maintaining the smooth operation of rotating shafts in heavy-duty environments.
