6209-2RS1/C3 Bearing Product Overview & Core Advantages
The 6209-2RS1/C3 is a single row deep groove ball bearing designed for exceptional performance in demanding applications. As a metric bearing, it excels in handling significant radial loads while also accommodating moderate axial loads in both directions. Its sealed construction (2RS1) provides robust protection against contaminants, and the C3 radial internal clearance makes it ideal for applications involving thermal expansion or where interference fits are used. This combination delivers a compact, reliable, and long-lasting solution for high-reliability machinery.
6209-2RS1/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6209 | Basic Bearing Series & Size | Denotes a single row deep groove ball bearing with a 45mm bore, 85mm OD, and 19mm width. |
| 2RS1 | Sealing Type | Features contact seals on both sides, providing superior protection against dust and moisture ingress compared to non-contact shields. |
| C3 | Radial Internal Clearance | Indicates a greater than normal clearance, suitable for applications with shaft interference fits or where operational heat generation is expected. |
6209-2RS1/C3 Bearing Structural Features & Performance Benefits
Robust Sealed Design: The NBR rubber contact seals (2RS1) effectively retain lubricant and exclude contaminants, significantly extending bearing service life and enabling maintenance-free operation in many environments.
Optimized Internal Geometry: The deep groove raceway and high-quality chrome steel construction provide high radial load capacity (7351 lbf dynamic / 4564 lbf static) and smooth operation.
Operational Versatility: The C3 clearance provides operational stability in applications prone to thermal expansion, preventing premature failure due to excessive preload. The ABEC 1 (ISO P0) tolerance class ensures consistent, reliable performance for general industrial use.
Wide Temperature Range: Constructed from chrome steel, this bearing operates effectively within a temperature range of -30°C to 120°C, accommodating a broad spectrum of industrial conditions.
