629-2RSH/C3LHT23 Bearing Product Overview & Core Advantages
The 629-2RSH/C3LHT23 is a metric single row deep groove ball bearing engineered for high reliability in demanding applications. Its key advantage lies in its sealed construction (2RSH) which provides superior protection against contamination, combined with a C3 radial internal clearance for stable operation under varying thermal conditions. This bearing is designed to primarily handle radial loads efficiently, making it an ideal choice for applications requiring a compact design, consistent performance, and long service life without relubrication.
629-2RSH/C3LHT23 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 629 | Basic bearing series, indicating a standard metric deep groove design. |
| 2RSH | Contact seals on both sides, made of NBR rubber. Offers excellent exclusion of contaminants and retention of grease. |
| C3 | Radial internal clearance greater than Normal (C0). Suitable for applications with expected thermal expansion or where interference fits are used. |
| LHT23 | Specifies the high-temperature grease used for lubrication, suitable for the specified operating temperature range. |
629-2RSH/C3LHT23 Bearing Structural Features & Performance Benefits
- Robust Sealing: The 2RSH contact seals provide a highly effective barrier against dust, moisture, and other particulate contaminants, significantly extending bearing life in harsh environments. This also ensures the pre-applied LHT23 grease is retained.
- Optimized Internal Clearance: The C3 clearance allows for differential thermal expansion between the inner and outer rings, preventing preload and ensuring smooth, low-vibration operation, especially important in applications with variable operating temperatures.
- High-Quality Materials: Manufactured from chrome steel for rings, balls, and cage, this bearing offers high strength, durability, and resistance to wear.
- Maintenance-Free Operation: The combination of effective sealing and high-quality, pre-applied grease makes this a lubricated-for-life bearing, reducing maintenance requirements and total cost of ownership.
629-2RSH/C3LHT23 Bearing Typical Application Areas
This versatile bearing is commonly found in:
- Small Electric Motors (e.g., cooling fans, appliance motors)
- Power Tools
- Conveyor Systems
- Agricultural Machinery
- Automotive Components (e.g., alternators, idler pulleys)
- General Industrial Machinery requiring reliable, sealed ball bearing performance.
