Product detailed description
bearing NU 218 E URB: High-Performance Cylindrical Roller Bearing
The bearing NU 218 E URB is a precision-engineered cylindrical roller bearing designed to deliver exceptional performance in heavy-duty industrial applications. Known for its durability and high load-carrying capacity, this bearing is ideal for use in machinery where both radial loads and high speeds are common. Its robust construction ensures long service life and reliable operation under demanding conditions.
This bearing features a double row of cylindrical rollers that enhance its ability to withstand high radial loads. The NU design allows for axial displacement of the shaft relative to the housing, which helps accommodate thermal expansion and misalignment, reducing stress on the bearing and connected components. The "E" designation indicates an improved internal design for increased load capacity compared to standard models.
The "URB" suffix in the NU 218 E URB model signifies that the bearing is supplied with a polyamide cage, which offers reduced friction and wear, contributing to quieter operation and extended bearing life. This cage design also supports higher speeds and improved lubrication retention, enhancing overall performance.
Key Features and Benefits
- High Load Capacity: Designed to handle heavy radial loads efficiently, making it suitable for demanding industrial environments.
- Thermal Expansion Accommodation: NU design permits axial displacement, preventing damage due to temperature variations and shaft movements.
- Polyamide Cage: Lightweight and wear-resistant cage reduces friction, noise, and vibration for smoother operation.
- Durability: Constructed from high-quality materials to ensure long service life and reliable performance.
- Versatility: Suitable for various applications including electric motors, gearboxes, pumps, and machine tools.
Specifications
The bearing NU 218 E URB typically has the following dimensions:
- Inner Diameter (d): 90 mm
- Outer Diameter (D): 160 mm
- Width (B): 40 mm
These dimensions ensure compatibility with standard shafts and housings, facilitating easy integration into existing machinery setups.
Applications
The NU 218 E URB bearing is widely used across industries such as manufacturing, automotive, mining, and heavy machinery. Its ability to support high radial loads and accommodate shaft movements makes it ideal for:
- Electric motors and generators
- Gearboxes and transmissions
- Pumps and compressors
- Machine tool spindles
- Conveyor systems
Choosing the bearing NU 218 E URB ensures enhanced reliability and efficiency in your machinery, reducing downtime and maintenance costs.
