Product detailed description
Bearing NU 319 EM P6 ZKL
The NU 319 EM P6 ZKL is a high-quality cylindrical roller bearing designed for demanding industrial applications. Manufactured by ZKL, a renowned producer in the bearing industry, this product guarantees excellent performance, durability, and precision. It is engineered to withstand heavy radial loads and operates efficiently at high speeds, making it suitable for various mechanical systems including electric motors, gearboxes, and heavy machinery.
This bearing features a NU-type design, which means it has two flanges on the outer ring and no flanges on the inner ring. This configuration allows the inner ring to move axially relative to the outer ring, accommodating thermal expansion or shaft displacement without compromising operational stability.
Key Features and Benefits
- Precision Class P6: The P6 tolerance class ensures high accuracy and reduced vibration, contributing to smoother operation and extended service life.
- Enhanced Cage Design: The "EM" suffix indicates an improved cage design, typically made from pressed steel or another advanced material for better strength and reduced friction.
- Reliable Radial Load Capacity: Cylindrical roller bearings like the NU 319 EM P6 are optimized to handle heavy radial loads with minimal deformation.
- Axial Displacement Accommodation: The NU design permits axial displacement of the shaft relative to the housing, which is beneficial in applications with thermal expansion or shaft misalignment.
- Durable Construction: Manufactured with high-quality steel and precision finishing, ensuring long-lasting performance under harsh operating conditions.
Technical Specifications
The NU 319 EM P6 ZKL follows standard dimensions for the NU 319 series bearings:
- Inner Diameter (d): 95 mm
- Outer Diameter (D): 180 mm
- Width (B): 43 mm
These dimensions comply with ISO standards for cylindrical roller bearings, facilitating easy replacement and compatibility in existing machinery.
Applications
The NU 319 EM P6 ZKL is widely used across various sectors, including:
- Heavy-duty electric motors
- Gearboxes and transmissions
- Industrial machinery and equipment
- Pumps and compressors
- Machine tool spindles
Its robust design and precision make it a preferred choice for engineers seeking reliable bearing solutions that ensure operational efficiency and longevity.
