SKF Needle Angular Contact Bearing: High Performance in Compact Design

The SKF Needle Angular Contact Bearing offers a unique combination of high load capacity and compact design, ideal for applications demanding superior performance in limited space. This bearing type utilizes a large number of small diameter rollers (needles) running directly on the inner and outer raceways, minimizing axial space requirements while maximizing radial load capacity. Its angular contact design further enhances its capabilities, allowing it to handle combined radial and axial loads effectively.

Key Features and Benefits:

• High Load Capacity: The multitude of small diameter rollers significantly increases the load-carrying capacity per unit of axial space compared to traditional ball bearings. This makes it perfect for applications experiencing substantial radial and moderate axial loads.
• Compact Design: The needle rollers' small diameter and the absence of a cage results in a remarkably compact bearing, ideal for space-constrained applications in machinery and equipment design.
• High Rigidity: The compact design and robust construction provide superior rigidity and stiffness, contributing to improved accuracy and stability in high-speed and precision applications.
• Angular Contact Design: This crucial feature allows the bearing to accommodate axial loads in one direction, making it suitable for applications with both radial and axial loading forces. The contact angle provides a degree of self-aligning capability, mitigating misalignment issues.
• Low Friction: Carefully engineered surfaces and precise manufacturing ensure minimal friction, resulting in increased efficiency and reduced energy consumption.
• Various Materials and Configurations: SKF offers needle angular contact bearings in a range of materials and configurations (including open and sealed types) to cater to diverse application needs. Specific materials can be chosen to optimize performance based on factors like operating temperature and environmental conditions.

Typical Applications:

• Automotive Industry: Transmission systems, gearboxes, and other high-load components.
• Agricultural Machinery: Harvesters, tractors, and other equipment subjected to heavy radial loads.
• Industrial Machinery: High-speed spindles, machine tools, and other applications demanding compact, high-performance bearings.
• Robotics: Articulated joints and other components requiring both precision and high load-carrying capacity.
• Aerospace: Lightweight and high-performance components where space and weight are critical considerations.

Specifications (General - Specific specifications will vary by model and size):

• Internal Clearance: Available in various preloads and internal clearances to optimize performance for specific application requirements.
• Seals: Options include open, shielded, and sealed configurations to protect against contamination and lubricant loss.
• Lubrication: Can be lubricated with various greases depending on operating conditions.
• Materials: High-quality bearing steel is typically used, with options for other materials depending on specific application demands.
