S634 2rs Bearing Product Overview & Core Advantages
The S634 2RS is a metric single row deep groove ball bearing engineered for high performance in compact spaces. 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 designed to handle significant radial loads and is optimized for applications demanding high rotational speeds and reliable, long-term operation. Its compact dimensions (4mm bore, 16mm OD, 5mm width) make it an ideal precision bearing solution for various industrial and precision instruments.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| S | Stainless Steel construction for enhanced corrosion resistance. |
| 634 | Standard bearing size designation (4mm bore, 16mm OD). |
| 2RS | Features two rubber seals, one on each side, providing excellent protection against dust and moisture, making it suitable for contaminated environments. |
S634 2rs Bearing Structural Features & Performance Benefits
- Robust Construction & High Speed: The single row deep groove raceway and stainless steel cage contribute to stable operation and a high limiting speed of 32,400 rpm, making it a capable high-speed bearing.
- Optimized Load Capacity: With a dynamic load rating of 231 lbf and a static load rating of 85 lbf, it is engineered to handle substantial radial loads efficiently.
- Sealed & Pre-Lubricated for Longevity: The Nitrile rubber (NBR) seals (2RS) effectively retain lubricant and exclude contaminants. The bearing comes pre-lubricated, reducing maintenance needs and ensuring immediate, reliable service.
- Precision & Stability: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3: 0.002mm to 0.013mm), it ensures smooth and precise running, minimizing vibration and noise.
S634 2rs Bearing Typical Application Areas
The S634 2RS is widely used in applications requiring small bearing dimensions, corrosion resistance, and high-speed capability. Key industries and equipment include:
- Precision Instruments: Optical encoders, measuring devices, and small medical apparatus.
- Small Electric Motors: High-speed spindles in dental handpieces, miniature fans, and drones.
- Office Automation Equipment: Printers, scanners, and copiers.
- Robotics and Automation: Small joint actuators and guide rollers.
