Overview
The NTN 6219NC3 is a precision radial ball bearing designed for demanding industrial applications requiring smooth, reliable rotation under radial loads. As a single row deep groove ball bearing with a snap ring groove, this bearing combines NTN’s engineering heritage with proven performance in machinery, motors, and mechanical drive systems.
Key Features
- Single row radial ball bearing configuration for radial load support
- Snap ring groove on outer ring for positive positioning and retention
- Open type design without seals or shields
- Pressed steel cage standard for structural integrity
- Uninterrupted deep groove raceway optimizes load distribution
Technical Specifications
The 6219NC3 is manufactured to ISO 287 deep groove ball bearing standards. Key dimensional and operational characteristics include bore diameter, outside diameter, and width dimensions suitable for metric shaft applications in the 95 mm bore class. The bearing operates across standard industrial temperature ranges and supports both grease and oil lubrication depending on application speed.
Typical Applications
This bearing is widely used in:
- Industrial electric motors and gearboxes
- Conveyor systems and material handling equipment
- Printing and textile machinery
- Pump and fan applications
- General purpose mechanical drive systems
- Machine tool spindles requiring radial load capacity
