210NTN9/C3 Bearing Product Overview & Core Advantages
The 210NTN9/C3 is a single row deep groove ball bearing designed for robust performance in demanding applications. Engineered to primarily handle radial loads, its open design and precision construction make it a versatile and reliable choice. A key feature is the snap ring groove on the outer ring, which simplifies axial location and mounting within a housing. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing offers excellent value and dependable operation for a wide range of industrial machinery.
210NTN9/C3 Bearing Model Code Explained, Specifications & Naming Convention
- 210: Standard designation for a medium-duty, single row deep groove ball bearing with a 50mm bore.
- N: Indicates the presence of a snap ring groove on the outer ring for secure axial positioning.
- TN9: Specifies the cage material. TN9 denotes a glass fiber reinforced nylon cage, which is lightweight, allows for high speeds, and offers quiet operation.
- /C3: Defines the internal clearance. C3 represents a clearance greater than normal, making it suitable for applications with expected thermal expansion or where interference fits are used.
210NTN9/C3 Bearing Structural Features & Performance Benefits
Optimized Load Capacity: The deep groove raceway and high-quality chrome steel construction enable efficient handling of significant radial dynamic load ratings (8790 lbf).
Simplified Mounting & Positioning: The integral snap ring groove eliminates the need for complex housing shoulders or end caps, reducing assembly time and cost while ensuring secure axial location.
High-Speed Capability: The lightweight and robust TN9 nylon cage minimizes centrifugal forces, contributing to a high limiting speed and stable operation.
Wide Operating Range: With a temperature range of -30°C to 120°C and a C3 radial internal clearance, this bearing is well-suited for applications subject to operational heat or press-fit conditions.
