S625 2rs Bearing Product Overview & Core Advantages
The S625 2RS is a metric single row deep groove ball bearing designed for high performance in compact spaces. Constructed entirely from stainless steel for superior corrosion resistance, it features integral nitrile rubber seals (2RS) on both sides for effective contamination exclusion and lubricant retention. This bearing is engineered to handle significant radial loads and is suitable for applications demanding smooth operation, ABEC 1 precision, and reliable service across a wide temperature range. Its compact dimensions (5mm bore, 16mm OD, 5mm width) make it an ideal solution for miniaturized and precision assemblies.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| S | Stainless Steel construction for enhanced corrosion resistance. |
| 625 | Standard bearing size designation (5mm bore, 16mm OD, 5mm width). |
| 2RS | Bearing is fitted with two Nitrile Rubber (NBR) Contact Seals on both sides. This provides excellent protection against contaminants and retains lubrication effectively. |
S625 2rs Bearing Structural Features & Performance Benefits
- Robust Construction & Corrosion Resistance: The all-stainless-steel (rings, balls, and cage) build ensures long-term performance in harsh or wash-down environments, resisting rust and corrosion.
- Effective Sealing: The 2RS rubber contact seals provide superior protection against dust, moisture, and other contaminants, significantly extending bearing life and reducing maintenance needs.
- Optimized Internal Geometry: With 7 precision balls and a stainless steel cage, the bearing ensures smooth, low-noise, and low-vibration operation, even at its maximum limiting speed.
- Precision & Clearance: Manufactured to ABEC 1 tolerance class with a standard MC3 radial internal clearance (0.002mm to 0.013mm), guaranteeing consistent and reliable performance for a wide range of applications.
S625 2rs Bearing Typical Application Areas
- Precision Instruments: Optical encoders, medical devices, and laboratory equipment.
- Small Electric Motors: Miniature DC motors, stepper motors, and fan motors.
- Office Automation Equipment: Printers, scanners, and copiers.
- Food & Beverage Processing Equipment: Where corrosion resistance and cleanability are paramount.
- Robotics & Automation: Small joints, guides, and actuators.
