629-2RSH Bearing Product Overview & Core Advantages
The 629-2RSH is a single row deep groove ball bearing designed for exceptional performance in compact spaces. Engineered with metric dimensions and manufactured to P6 tolerance class, this bearing delivers high precision and reliability. Its key advantage lies in its ability to handle primarily radial loads efficiently while also accommodating moderate axial loads in both directions. The sealed construction (2RSH) with pre-applied grease lubrication ensures long-term, maintenance-free operation, making it ideal for applications demanding high reliability and cleanliness.
629-2RSH Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 629 | Basic bearing series, indicating a single row deep groove ball bearing with standard dimensions (9mm bore, 26mm OD, 8mm width). |
| 2RSH | Designates contact seals on both sides. The RSH suffix indicates NBR (Nitrile Rubber) seals with steel reinforcements, providing superior protection against contaminants and effective grease retention. |
629-2RSH Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Manufactured to P6 tolerance class with a CN radial internal clearance, ensuring precise running accuracy and stable operation under load.
- Robust Load Capacity: Features a dynamic load rating of 1068 lbf and a static load rating of 441 lbf, providing reliable performance under significant radial stresses.
- Optimized High-Speed Performance: The stainless steel cage and optimized internal geometry contribute to a high limiting speed of 19,000 rpm, suitable for demanding rotational applications.
- Maintenance-Free & Long Service Life: The double-sided contact seals (2RSH) effectively shield the bearing from dust and moisture. Pre-lubricated with high-quality grease, it operates reliably across a temperature range of -30°C to 120°C without requiring re-lubrication.
- Premium Material Construction: Rings and balls made from chrome steel offer high wear resistance and durability, while the stainless steel cage provides excellent corrosion resistance.
629-2RSH Bearing Typical Application Areas
- Electric Motors: Small to medium-sized motors requiring quiet operation and long life.
- Precision Instruments: Optical encoders, measuring devices, and laboratory equipment.
- Office Automation Equipment: Printers, scanners, and copiers.
- Small Power Tools: Drills, grinders, and other handheld tools.
- Medical Devices: Low-noise, high-reliability applications such as small pumps and dental handpieces.
- Automotive Auxiliary Units: Fans, blowers, and small pumps.
