NKIA5905 NKE needle roller bearing

NKE NKIA5905 Combined Needle Roller Bearing (Radial-Axial)

The NKE NKIA5905 is a sophisticated rolling component that integrates a radial needle roller bearing and a single-row angular contact ball bearing into a single, non-separable unit. This design allows the bearing to accommodate high radial loads and unidirectional axial loads simultaneously. Part of the 59 series, it features a low cross-section, making it the perfect choice for space-restricted applications on 25 mm shafts. The open design facilitates free lubricant flow, which is essential for heat dissipation at high rotational speeds.

Application

• Precision Machine Tools: Support for auxiliary shafts and spindles requiring rigid axial locating.
• Industrial Gearboxes: Compact reducers handling complex forces from helical gears.
• Automation & Robotics: Joints and arm drives with high power density requirements.
• Automotive Industry: Transmission components and high-pressure pumps.
• Textile Machinery: High-speed thread guides and drive rollers.

Technical Specification

• Manufacturer: NKE Bearings (Austria).
• Designation: NKIA5905.
• Dimensions: 25 mm (ID) x 42 mm (OD) x 23 mm (Width).
• Type: Combined (radial needle + angular contact ball).
• Design: Open (requires external lubrication).
• Material: High-grade heat-stabilized bearing steel.

Features and Benefits

• Two Bearings in One: Eliminates the need for separate thrust bearings, shortening shaft length and reducing assembly costs.
• High Rigidity: The combination of needle rollers and angular contact balls provides precise shaft guidance without axial play.
• Low Cross-Section (59 Series): Enables the use of a thicker, stiffer shaft while maintaining a small housing diameter.
• Austrian Precision: NKE quality ensures low vibration levels, quiet operation, and high fatigue life.
• Lubricant Compatibility: The open design is perfect for oil bath or centralized lubrication systems.

Why Choose This Product

By choosing the NKE NKIA5905, you are opting for a "Premium Locating Unit." In applications where standard needle bearings would fail due to axial thrust, the NKIA series excels. It is the go-to solution for engineers and maintenance professionals designing next-generation machinery – smaller, lighter, and more efficient. Choosing Austrian NKE quality minimizes the risk of unplanned downtime in your facility.
