629-2RSH/C3LHT23F7 Bearing Product Overview & Core Advantages
The 629-2RSH/C3LHT23F7 is a single row deep groove ball bearing designed for reliable performance in demanding applications. This metric bearing features integral contact seals (2RSH) for effective contamination exclusion and is pre-lubricated with a high-performance grease suitable for a wide temperature range. Its C3 radial internal clearance makes it ideal for applications with thermal expansion or where interference fits are used. Engineered with chrome steel components and built to ABEC 1 | ISO P0 tolerance standards, it offers a robust solution for handling radial loads with high operational reliability.
629-2RSH/C3LHT23F7 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 629 | Basic bearing series, indicating a single row deep groove design with specific dimensions (9mm bore, 26mm OD, 8mm width). |
| 2RSH | Bearing is fitted with two contact seals on both sides. The "RSH" designation typically indicates a Nitrile Rubber (NBR) seal with a steel insert, offering superior sealing effectiveness compared to non-contact shields. |
| C3 | Specifies a greater than normal radial internal clearance. This is beneficial in applications where thermal expansion is expected or where tight fits are used, preventing premature bearing failure due to excessive preload. |
| LHT23 | Indicates the bearing is pre-lubricated with a specific grease. LHT23 is a lithium-based grease suitable for a wide temperature range (-30°C to +120°C), offering good mechanical stability and corrosion protection. |
629-2RSH/C3LHT23F7 Bearing Structural Features & Performance Benefits
- Robust Sealing for Enhanced Lifespan: The double-contact seals (2RSH) provide excellent protection against contaminants like dust and moisture. This significantly extends the bearing's service life in harsh environments, making it a low-maintenance component.
- Optimized Internal Clearance: The C3 radial clearance accommodates dimensional changes caused by thermal expansion or interference fits, ensuring smooth operation and preventing binding, which is critical for maintaining performance under varying operational conditions.
- High-Quality Material Construction: Manufactured entirely from chrome steel, including rings, balls, and cage, this bearing ensures high strength, durability, and consistent performance under the specified radial dynamic load rating of 873 lbf.
- Ready-to-Use Lubrication: Pre-filled with LHT23 grease, the bearing is lubricated for its entire service life in many applications, simplifying installation and reducing maintenance requirements. The grease is effective within the stated temperature range of -30°C to 120°C.
629-2RSH/C3LHT23F7 Bearing Typical Application Areas
This versatile and sealed bearing is commonly specified in a wide range of equipment and industries, including:
- Electric Motors: Small to medium-sized motors requiring reliable, sealed bearings for fan ends or other auxiliary drives.
- Automotive Components: Applications such as alternators, idler pulleys, and water pumps where contamination resistance is crucial.
- Industrial Gearboxes and Transmissions: Used in light-duty gearboxes for auxiliary shafts.
- Material Handling Equipment: Conveyor rollers, pulleys, and other components exposed to dusty environments.
- Agricultural Machinery: Various drives and implements where protection from dirt and moisture is necessary.
- Appliance Industry: Found in washing machines, dryers, and other household appliances demanding quiet and reliable operation.
