INA HK Series Drawn Cup Needle Roller Bearing (15mm Inner)

The INA HK series drawn cup needle roller bearing is a compact, high-performance solution engineered for applications where space is limited but radial load capacity must remain high. Manufactured in Germany to strict industrial standards, this bearing features a steel cage and needle rollers housed within a thin, drawn cup outer ring. Unlike standard bearings, the HK type lacks an inner ring, allowing the shaft itself to serve as the inner raceway, which maximizes the usable cross-section of the shaft.

Key Features

• Compact Design: The sleeve-like structure allows installation in very narrow radial spaces, ideal for tight mechanical assemblies.
• High Radial Load Capacity: Optimized needle rollers provide exceptional load-bearing performance relative to their size.
• German Engineering: Produced by INA, a leader in rolling element technology, ensuring high precision, durability, and reliability.
• Shaft Integration: The absence of an inner ring simplifies shaft design and increases the structural integrity of the rotating component.

Applications

These bearings are widely used in automotive transmissions, industrial machinery, agricultural equipment, and hydraulic systems where high radial forces are present in confined areas. They are a critical component in gearboxes, pump housings, and conveyor mechanisms requiring long service life under demanding conditions.
