6704 2rs Bearing Product Overview & Core Advantages
The 6704 2RS is a metric single row deep groove ball bearing designed for reliable performance in compact spaces. This sealed bearing excels in applications requiring robust radial load capacity and protection from contamination. Manufactured to ABEC-1 precision tolerances, it offers consistent operation and is pre-lubricated for immediate installation, making it an ideal choice for high-volume OEM applications where reliability and cost-effectiveness are paramount.
6704 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6704 | Basic bearing designation indicating a metric, single row deep groove ball bearing with a 20mm bore, 27mm outside diameter, and 4mm width. |
| 2RS | Denotes contact seals on both sides. The RS seals are made of Nitrile Rubber (NBR), providing excellent protection against dust, moisture, and other contaminants, while retaining lubrication effectively. |
6704 2rs Bearing Structural Features & Performance Benefits
- Robust Radial Load Capacity: The deep groove raceway and single row design are optimized to handle significant radial loads (227 lbf dynamic / 162 lbf static), providing stable support for rotating shafts.
- Effective Sealing: The 2RS double-contact seals ensure a high degree of protection, making the bearing suitable for environments where dirt or moisture is present, significantly extending service life by retaining lubricant and excluding contaminants.
- Precision & Consistency: Built to ABEC-1 tolerance class with a C0 radial internal clearance (0.006mm to 0.020mm), this bearing delivers smooth, low-vibration, and predictable performance.
- Compact & Lightweight Design: With a cross-section of just 4mm and a weight of only 5.9g, it is an excellent solution for applications with severe space and weight constraints.
- Wide Operating Temperature: The standard lubricant and chrome steel construction allow for a functional temperature range from -30°C to 110°C.
6704 2rs Bearing Typical Application Areas
This versatile bearing is commonly specified in:
- Small Electric Motors: Used in fans, blowers, and small appliance motors.
- Office Automation Equipment: Ideal for printers, scanners, and copiers.
- Precision Instruments: Suitable for medical devices, optical equipment, and measuring instruments.
- Automotive Auxiliary Units: Found in components like idler pulleys, small pumps, and actuators.
- General Machinery: Applicable in various light-duty industrial machinery requiring a compact, sealed ball bearing.
