S604 2rs Bearing Product Overview & Core Advantages
The S604 2RS is a metric single row deep groove ball bearing designed for high reliability in compact applications. Constructed entirely from stainless steel for superior corrosion resistance, it features integral rubber seals (2RS) on both sides for effective contamination protection. This bearing is engineered to handle primarily radial loads and is characterized by its low friction, smooth operation, and long service life, making it an ideal choice for applications demanding precision and durability in challenging environments.
S604 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S604 | Basic bearing designation indicating a metric, single row deep groove ball bearing with a 4 mm bore, 12 mm OD, and 4 mm width. |
| 2RS | Signifies that the bearing is equipped with two rubber contact seals (one on each side). These seals provide excellent protection against dust and moisture ingress, enhancing bearing life in contaminated environments. |
S604 2rs Bearing Structural Features & Performance Benefits
- Robust Sealing: The NBR rubber contact seals (2RS) effectively shield the internal components from contaminants while retaining lubricant, contributing to a maintenance-free and long-lasting operation.
- Corrosion Resistance: The use of stainless steel for the rings, balls, and cage ensures excellent performance in humid or corrosive environments, aligning with ROHS and REACH compliance.
- Precision & Smooth Operation: Manufactured to ABEC1 tolerance class with a MC3 radial internal clearance (0.002mm to 0.013mm), this bearing offers reliable and consistent performance for a wide range of general-purpose applications.
- Optimized Internal Geometry: The deep groove raceway and complement of 7 precision balls enable efficient handling of radial dynamic loads up to 165 lbf and smooth rotation.
S604 2rs Bearing Typical Application Areas
- Small Electric Motors and Gear Motors
- Precision Instruments and Optical Devices
- Office Automation Equipment (e.g., Printers, Scanners)
- Medical Devices and Laboratory Equipment
- Food Processing Machinery (where corrosion resistance is key)
- Various Low-Torque, High-Speed Drives
