209 NR Bearing Product Overview & Core Advantages
The 209 NR is a single row deep groove ball bearing designed for robust radial load applications. Its defining feature is the integral snap ring on the outer ring, which simplifies axial location within a housing, reducing assembly complexity and cost. Manufactured from high-grade Chrome Steel with a stainless steel cage, it offers reliable performance, a high limiting speed, and is supplied as an open (unsealed) unit for versatility in lubrication system selection. This bearing is an excellent choice for applications requiring a compact, easily installed, and cost-effective solution.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 209 | Standard bearing series designation indicating the bearing dimensions: 45mm bore, 85mm OD, 19mm width. |
| NR | Signifies that the bearing outer ring has a snap ring groove and a snap ring is fitted. This feature aids in axial location. |
209 NR Bearing Structural Features & Performance Benefits
- Snap Ring Locating Feature: The fitted snap ring on the outer ring provides a positive axial location, eliminating the need for complex housing shoulders or end caps. This simplifies housing design, reduces machining costs, and ensures secure positioning.
- High-Speed Capability: The combination of a precision deep groove raceway and a lightweight, durable stainless steel cage enables stable operation at high limiting speeds up to 8,500 rpm.
- Robust Load Capacity: Engineered to handle significant radial dynamic loads (7913 lbf) and radial static loads (6744 lbf), ensuring longevity in demanding applications.
- Open Design for Flexibility: The open (unsealed) construction allows for the use of various lubrication methods (oil bath, grease, oil mist) to suit specific operational environments and temperature ranges (-30°C to 120°C).
209 NR Bearing Typical Application Areas
This bearing is ideally suited for a wide range of industrial machinery where ease of installation and secure axial location are paramount. Common applications include:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Fans and Blowers
- Agricultural Machinery
- Material Handling Equipment
- Pumps and Compressors
