S679 2rs Bearing Product Overview & Core Advantages
The S679 2RS is a metric single row deep groove ball bearing engineered for compact spaces requiring high reliability. Its sealed construction with nitrile rubber contact seals (2RS) provides robust protection against contaminants, making it an ideal maintenance-free solution. Manufactured entirely from stainless steel, it offers excellent corrosion resistance. This bearing is designed to primarily handle radial loads efficiently within a compact envelope of 9mm bore and 14mm outside diameter, delivering consistent performance in demanding applications.
S679 2rs Bearing Model Code Explained, Specifications & Naming Convention
- S679: Basic model number denoting a metric, single row deep groove ball bearing with a 9mm bore, 14mm OD, and 4.5mm width.
- 2RS: Signifies the bearing is fitted with two Nitrile Rubber (NBR) Contact Seals, one on each side. This provides superior sealing effectiveness against dust, moisture, and other contaminants compared to non-contact shields.
S679 2rs Bearing Structural Features & Performance Benefits
Robust Sealed Design: The dual rubber contact seals (2RS) ensure a high degree of protection, retaining lubricant and excluding harmful particles, which is critical for longevity in unclean environments.
Corrosion Resistance: Constructed entirely from stainless steel for the rings, balls, and cage, this bearing is suitable for applications exposed to moisture, mild chemicals, or where corrosion is a concern.
Precision & Reliability: Built to ABEC1 tolerance class and featuring a controlled MC3 radial internal clearance (0.002mm to 0.013mm), it ensures smooth, low-noise, and low-vibration operation.
High-Speed Capability: With a limiting speed of 32,400 rpm, it is well-suited for high-velocity applications. The deep groove raceway and optimized internal geometry contribute to stable operation at high rotational speeds.
S679 2rs Bearing Typical Application Areas
The S679 2RS is widely used in applications demanding compact size, corrosion resistance, and sealed reliability. Key sectors include:
- Small Precision Motors (e.g., drones, miniature fans)
- Medical and Dental Equipment (e.g., handpieces, small pumps)
- Food Processing Machinery (where stainless steel and sealing are mandatory)
- Office Automation Equipment (e.g., printers, scanners)
- Instrumentation and Precision Guiding Mechanisms
