SF604 2rs Bearing Product Overview & Core Advantages
The SF604 2RS is a single row deep groove ball bearing designed for compact applications requiring reliable performance. Engineered with stainless steel construction throughout its rings, balls, and cage, it offers excellent corrosion resistance. A key feature is its integral rubber seals (2RS) on both sides, which effectively retain lubrication and exclude contaminants, making it suitable for applications where maintenance-free operation is desired. This bearing is optimized to handle primarily radial loads and is capable of high-speed operation up to 43,200 rpm, making it an ideal choice for precision instruments and small machinery.
SF604 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF604 | The base bearing designation, indicating a metric, single row deep groove ball bearing with a 4 mm bore, 12 mm outside diameter, and 4 mm width. |
| 2RS | Signifies that the bearing is fitted with Rubber Seals on both sides. This provides superior protection against contamination and moisture, ensuring long-term lubrication integrity. |
SF604 2rs Bearing Structural Features & Performance Benefits
- Robust Stainless Steel Construction: All critical components, including the rings, 7 precision balls, and cage, are manufactured from stainless steel. This provides excellent resistance to rust and corrosion, extending bearing service life in challenging environments.
- Effective Sealing Solution: The Nitrile Rubber (NBR) seals (2RS) are a standout feature, offering reliable protection from dust, dirt, and other particulates. This design is crucial for maintaining performance in applications where contamination is a concern.
- High-Speed Capability: With a limiting speed of 43,200 rpm, this bearing is engineered for demanding, high-rotation applications. The low-friction design and effective sealing contribute to its stable operation at high velocities.
- Precision and Reliability: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3 group), this bearing ensures consistent and smooth running, which is vital for the accuracy of precision devices.
