Product Overview: The NK 50*64*14 Needle Roller Bearing
The NK 50*64*14 is a precision-engineered machined ring needle roller bearing, a key component in our NK Series collection. With a bore diameter of 50mm, an outer diameter of 64mm, and a width of 14mm, this bearing is designed for applications requiring high radial load capacity within a minimal space. A defining characteristic of the Without Inner Ring design is its ability to use a hardened and ground shaft as the inner raceway, allowing for a more compact and cost-effective assembly. This makes it an excellent choice for a wide variety of industrial and automotive applications where space is at a premium.
As part of our extensive range of Needle Roller Bearings, the NK 50*64*14 is manufactured to exacting standards to ensure reliable performance and durability. Its robust construction and high precision make it suitable for demanding operational conditions. Explore our full catalog to find the perfect bearing solution for your machinery.
Key Features of the NK 50*64*14 Bearing
- High Radial Load Capacity: Features a full complement of needle rollers to support heavy radial loads.
- Compact and Space-Saving: The absence of an inner ring provides a low cross-sectional height, ideal for radially constrained spaces.
- Machined Outer Ring: Offers high rigidity and precise roller guidance for stable operation.
- Direct Shaft Mounting: Designed to run directly on a hardened and ground shaft, simplifying design and reducing component count.
- Cage-Guided Rollers: The cage retains and guides the rollers, reducing friction and heat generation, which is suitable for higher speeds.
- Precision Manufacturing: Produced to strict industry tolerances for consistent fit and performance.
Common Applications
- Automotive Transmissions: Used in gearboxes, clutches, and driveshafts where space and load capacity are critical.
- Industrial Gearboxes: Provides robust support for gears and shafts in heavy-duty machinery.
- Pumps and Compressors: Ensures smooth and reliable operation of rotating components.
- Power Tools: Ideal for drills, saws, and other handheld equipment requiring compact, high-performance bearings.
- Two-Stroke Engines: Commonly used in connecting rod and wrist pin applications.
- Agricultural Machinery: Suitable for various components in tractors, harvesters, and other farm equipment.
- Printing and Textile Machinery: Offers precise rotational support for rollers and spindles.
Benefits of Using the NK 50*64*14 Bearing
- Optimized Space Utilization: Allows for a larger shaft diameter or a smaller housing bore, maximizing design efficiency.
- Reduced Assembly Cost: Eliminating the need for a separate inner ring can lower the overall cost and complexity of the bearing arrangement.
- Enhanced Rigidity: The solid, machined outer ring provides superior support compared to drawn cup alternatives.
- Improved Equipment Lifespan: High load capacity and durable construction contribute to longer service life and reduced maintenance.
- Efficient Operation: Low friction design minimizes power loss and heat, improving overall machine efficiency.
- Design Flexibility: Enables engineers to create more compact and lightweight machinery without sacrificing performance.
