6207-2RS1NR/C3 HT51 Bearing Product Overview & Core Advantages
The 6207-2RS1NR/C3 HT51 is a metric single row deep groove ball bearing engineered for high reliability in demanding applications. Its key advantage lies in its ability to efficiently handle radial loads while offering operational stability. The bearing features integrated seals for contaminant exclusion and a snap ring groove on the outer ring for simplified axial location and mounting. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides consistent performance and is ideal for applications requiring robust, maintenance-free operation.
6207-2RS1NR/C3 HT51 Bearing Model Code Explained, Specifications & Naming Convention
The model number 6207-2RS1NR/C3 HT51 provides a complete technical specification:
- 6207: Basic designation for a metric single row deep groove ball bearing with a 35mm bore, 72mm OD, and 17mm width.
- 2RS1: Indicates the bearing is equipped with two contact seals (one on each side), providing effective protection against contaminants and retaining lubricant.
- NR: Signifies the outer ring has a snap ring groove, enabling secure and straightforward axial positioning within a housing.
- C3: Denotes a greater than normal radial internal clearance. This is beneficial for applications with significant thermal expansion or where interference fits are used.
- HT51: Specifies the use of a high-temperature, synthetic hydrocarbon grease lubricant, suitable for the specified temperature range of -30°C to 120°C.
6207-2RS1NR/C3 HT51 Bearing Structural Features & Performance Benefits
The design of the 6207-2RS1NR/C3 HT51 translates into distinct performance benefits:
- Robust Load Capacity: Constructed from chrome steel for both rings and balls, this bearing offers a high dynamic load rating of 5778 lbf and a static load rating of 3462 lbf, ensuring durability under significant radial loads.
- Enhanced Sealing & Contamination Resistance: The 2RS1 contact seals effectively shield the internal components from dust, moisture, and other contaminants, while also retaining the factory-applied HT51 grease for long-term, maintenance-free operation.
- Simplified Installation & Axial Location: The snap ring groove (NR) on the outer ring allows for easy and secure mounting, eliminating the need for complex housing shoulders and reducing assembly time.
- Optimized for Thermal & Fit Conditions: The C3 radial internal clearance accommodates thermal expansion and interference fits, preventing premature failure due to excessive preload in challenging operating environments.
6207-2RS1NR/C3 HT51 Bearing Typical Application Areas
This versatile bearing is commonly specified in a wide range of industrial machinery and equipment, including:
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Material Handling Conveyors
- Agricultural Machinery
- Automotive Components (e.g., alternators, idler pulleys)
