6315 NR Bearing Product Overview & Core Advantages
The 6315 NR is a single row deep groove ball bearing designed for exceptional radial load capacity and reliable performance in demanding applications. This metric bearing features a snap ring groove on its outer ring, enabling simplified axial location within a housing without the need for complex machining or additional components. Manufactured from high-grade chrome steel with a stainless steel cage, it offers robust durability and consistent operation. Its open design allows for versatile lubrication options, making it suitable for a wide range of industrial machinery where high radial dynamic load rating and straightforward installation are critical.
6315 NR Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance & Advantage |
|---|---|---|
| NR | Snap Ring Groove (fitted on outer ring) | Facilitates secure axial positioning and simplifies housing design, reducing assembly time and cost. |
| No Seal Suffix | Open (non-contact) bearing | Enables high-speed operation and allows for custom lubrication strategies based on application needs. |
6315 NR Bearing Structural Features & Performance Benefits
- High Radial Load Capacity: The optimized single row deep groove raceway geometry and high-quality chrome steel construction enable it to handle a substantial radial dynamic load rating of 26,752 lbf, ensuring long service life under heavy loads.
- Simplified Axial Location: The integrated snap ring groove (NR) on the outer diameter provides a positive locating feature, which enhances assembly accuracy and stability within the housing.
- High-Speed Capability: The lightweight and durable stainless steel cage maintains ball alignment and stability, contributing to a high limiting speed of 5,600 rpm.
- Versatile Application Range: The open seal type and standard CN radial internal clearance make it adaptable to various operating conditions and temperature ranges from -30°C to 120°C.
- Precision & Reliability: Manufactured to P0 tolerance class with tight dimensional control on the 75 mm bore and 160 mm outside diameter, it guarantees consistent performance and interchangeability.
