6209-2RS1NR Bearing Product Overview & Core Advantages
The 6209-2RS1NR is a single row deep groove ball bearing designed for exceptional reliability in demanding applications. This sealed bearing features a snap ring groove on its outer ring for secure axial location within a housing. Its primary advantages include robust radial load capacity, effective sealing for contaminant exclusion, and simplified installation due to the locating snap ring. Engineered with precision tolerances (ABEC 1 | ISO P0) and manufactured from high-grade chrome steel, it delivers consistent performance and long service life.
Model Code Breakdown
- 6209: Basic model number denoting a single row deep groove ball bearing with a 45mm bore and medium cross-section.
- 2RS1: Signifies that the bearing is equipped with contact seals on both sides. The "RS" indicates rubber seals, providing superior protection against contaminants and moisture retention compared to shielded variants.
- NR: Denotes that the outer ring has a snap ring groove. This feature allows for simplified axial location and secure mounting in a housing without the need for complex housing shoulders or end caps.
6209-2RS1NR Bearing Structural Features & Performance Benefits
Robust Construction & High Load Capacity: Built from hardened chrome steel for both rings, balls, and cage, this bearing offers high strength and durability. Its deep groove raceway geometry is optimized to support significant radial loads (dynamic rating: 7351 lbf), making it suitable for a wide range of industrial applications.
Enhanced Sealing & Contamination Resistance: The 2RS1 dual-contact seals effectively prevent the ingress of dirt, dust, and moisture while retaining lubricant. This design significantly extends bearing life in harsh or dirty environments and reduces maintenance requirements.
Simplified Installation & Axial Location: The snap ring groove (NR) on the outer ring facilitates easy and secure mounting. This feature is critical for applications where precise axial positioning is required, simplifying housing design and assembly processes.
Precision & Speed Performance: Manufactured to ABEC 1 precision class with a standard CN radial internal clearance, it ensures smooth and quiet operation. The bearing is capable of operating at high rotational speeds (limiting speed: 7,700 rpm), suitable for various motor and drive applications.
