HK 2026/4 Drawn Cup Needle Roller Bearing | 20x26x4 mm | High Capacity CR Series
The HK 2026/4 is a high-performance Drawn Cup Needle Roller Bearing engineered for applications requiring maximum load capacity within a minimal radial envelope. Manufactured under the stringent CR quality standard, this bearing features a thin-walled, hardened steel drawn outer cup and a complement of high-precision needle rollers, providing exceptional rigidity and longevity. Its open-end design facilitates efficient lubrication flow, ensuring optimal thermal stability even under high-speed oscillatory or rotary motion. This specific geometry (20 mm bore, 26 mm OD, 4 mm width) makes it ideal for direct installation onto a hardened shaft without the need for an inner ring, streamlining the assembly process and maximizing component integration space.
Designed for demanding industrial environments, the HK 2026/4 excels in automotive transmissions, power tools, gearboxes, and agricultural machinery where radial space is limited but high dynamic load performance is critical. The press-fit installation of the drawn cup simplifies housing design while maintaining highly accurate seating. Choosing the CR quality HK 2026/4 ensures reduced downtime, superior fatigue life, and reliable operation across a wide operating temperature range, positioning it as a cost-effective solution for improving overall machine efficiency and maintaining high productivity outputs.
Key Features
Minimal Radial Cross-Section: Optimized for installations where radial space is severely restricted.
High Dynamic Load Capacity: Handles significant loads relative to its small size and low mass.
Cost-Effective Installation: Designed for a simple press-fit into the housing, eliminating the need for complex axial securing elements.
Enhanced Reliability (CR Standard): Consistent dimensional accuracy and material integrity ensuring long operational life.
Shaft Compatibility: Operates directly on a hardened and ground shaft surface (inner ring typically not required).
