Product Overview: NKS 50 Heavy-Duty Needle Roller Bearing
The NKS 50 is a high-capacity machined ring needle roller bearing designed for demanding industrial applications. With key dimensions of 50x65x22mm (shaft diameter x outer diameter x width), this bearing offers a compact and robust solution for arrangements with high radial loads. As part of our Machined Ring Bearings collection, the NKS 50 is engineered without an inner ring to run directly on a hardened and ground shaft. This design minimizes the radial space required, making it an excellent choice for compact machinery designs. Explore our full range of Needle Roller Bearings to find the perfect component for your engineering needs.
Key Features of the NKS 50 Bearing
- High Radial Load Capacity: Features a full complement of rollers within a small cross-section, providing exceptional load-carrying ability.
- Space-Saving Design: By operating directly on the shaft, it eliminates the need for an inner ring, allowing for a smaller and lighter bearing arrangement.
- Heavy-Duty Construction: The rigid, machined outer ring provides high stability and is suitable for heavy-duty applications and shock loads.
- Precision Guidance: A robust cage accurately guides the needle rollers, ensuring stable operation even at high speeds and reducing friction.
- High Rigidity: The solid outer ring prevents deformation under load, ensuring consistent performance and shaft alignment.
- Optimized for Hardened Shafts: Designed to be used where the shaft itself can serve as the raceway, offering a cost-effective and integrated solution.
Common Applications
- Industrial Gearboxes: Provides robust support for gears and shafts in high-torque environments.
- Automotive Transmissions: Used in transmission systems where space is limited and high radial loads are present.
- Construction Equipment: Ideal for pivot pins, hydraulic pumps, and other heavy-duty machinery components.
- Two-Stroke Engines: Commonly used for connecting rod and piston pin applications due to its high performance.
- Printing Presses: Ensures smooth and precise rotation of rollers under significant pressure.
- Agricultural Machinery: Withstands the harsh conditions and heavy loads found in equipment like combines and balers.
- Material Handling Systems: Suitable for conveyor rollers and lifting equipment requiring durable rotational support.
Benefits of Using the NKS 50 Bearing
- Reduced Machine Size and Weight: The compact, inner-ring-less design allows for smaller and lighter final products.
- Enhanced Durability: Built to withstand heavy radial loads and harsh operating conditions, leading to a longer service life.
- Improved Operational Efficiency: Low friction and high rigidity contribute to smoother machinery operation and reduced energy consumption.
- Simplified Assembly: Fewer components in the bearing arrangement can streamline the installation process.
- Cost-Effective Solution: Eliminates the cost of a separate inner ring when the shaft can be suitably prepared as a raceway.
- Reliable Performance: Provides consistent and dependable operation in critical applications, minimizing downtime and maintenance.
