INA HK 18 mm Drawn Cup Needle Roller Bearing

The INA HK series 18 mm drawn cup needle roller bearing is a specialized component engineered for applications where space is limited but radial load capacity must remain high. As a sleeve-type bearing, it lacks an inner ring, allowing it to be mounted directly onto a hardened, precision-ground shaft. This design maximizes the internal space available for the needle rollers, ensuring optimal load distribution and durability.

Key Features

• Compact Design: The drawn cup structure and absence of an inner ring minimize the overall cross-section, ideal for tight mechanical clearances.
• High Radial Load Capacity: Despite its small size, the dense arrangement of needle rollers supports significant radial forces.
• German Engineering: Manufactured by INA (part of the Schaeffler Group), ensuring strict quality control, consistent tolerances, and reliable performance.
• Direct Shaft Mounting: Designed to run directly on the shaft, reducing assembly complexity and component count.

Applications

This bearing is widely used in automotive transmissions, industrial gearboxes, agricultural machinery, and various mechanical systems where compactness and strength are critical. It is particularly suitable for rotating shafts that experience high radial stress in confined environments.
