Power Drive NJ219 Cylindrical Roller Bearing (pack of 1)

Power Drive NJ219 Cylindrical Roller Bearing: Detailed Description

The Power Drive NJ219 cylindrical roller bearing is engineered to meet the demanding requirements of various industrial applications. This bearing type is designed to support high radial loads and can accommodate moderate axial loads in one direction, making it an excellent choice for machinery that requires robust and reliable components.

Design and Structure

The NJ219 bearing features a two-part inner ring with integral flanges on one side, allowing for axial movement of the shaft within the bearing while maintaining the ability to handle radial loads. The outer ring is designed without flanges, enabling easy assembly and disassembly. The cylindrical rollers are arranged in a way that they make linear contact with the raceways, which minimizes contact stress and enhances load distribution.

Key Features

• High Load Capacity: The cylindrical roller design allows the NJ219 to support significant radial loads, making it suitable for applications where heavy weights are involved.
• Low Friction: The shape of the rollers minimizes friction during operation, leading to improved efficiency and reduced heat generation.
• Versatile Applications: Commonly used in electric motors, pumps, gearboxes, and various industrial machinery, the NJ219 is versatile enough to fit a wide range of mechanical systems.
• Durability: Manufactured from high-quality steel, this bearing is designed for long service life and reliability under harsh operating conditions.

Specifications

• Inner Diameter (ID): 95 mm
• Outer Diameter (OD): 170 mm
• Width (B): 32 mm
• Dynamic Load Rating (C): Typically high, suitable for applications with dynamic loading conditions.
• Static Load Rating (C0): Also designed for high static load capabilities, ensuring that the bearing can handle static forces without deformation.

Applications

The NJ219 cylindrical roller bearing is particularly well-suited for:

• Electric Motors: Provides reliable operation and supports the high speeds and loads typically found in motor applications.
• Pumps: Facilitates smooth operation and longevity in various pumping systems, including water, oil, and chemical pumps.
• Gearboxes: Essential in transmitting power efficiently and supporting heavy loads in gear assemblies.
