629-RSHTN9/C3LT Bearing Product Overview & Core Advantages
The 629-RSHTN9/C3LT is a single row deep groove ball bearing engineered for exceptional performance in compact spaces. This metric bearing features a sealed construction, making it an ideal solution for applications demanding high reliability with minimal maintenance. Its design is optimized to handle primarily radial loads efficiently. Manufactured to ABEC 1 | ISO P0 tolerance standards and featuring a C3 radial internal clearance, this bearing ensures consistent operation and is suitable for a wide temperature range from -30°C to 120°C. Its compliance with ROHS and REACH directives further underscores its suitability for modern, regulated industries.
629-RSHTN9/C3LT Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| RS | Contact Rubber Seal on one side | Provides effective protection against contaminants, retaining lubrication. |
| HTN9 | Nylon Cage (often designated as TN9), potentially with high-temperature considerations. | Contributes to quiet operation, low friction, and is suitable for the specified temperature range. |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion, ideal for applications with expected temperature variations. |
| LT | Low Temperature Grease | Ensures reliable lubrication and smooth operation from -30°C to 120°C. |
629-RSHTN9/C3LT Bearing Structural Features & Performance Benefits
- Robust Sealed Design: The inclusion of a contact rubber seal (RS) effectively shields the internal components from dust, moisture, and other contaminants. This significantly extends the bearing's service life by preserving the integrity of the low-temperature grease and preventing premature wear.
- Optimized Internal Clearance: The C3 radial internal clearance is a key feature that allows for thermal expansion of the bearing components during operation. This makes the bearing particularly suited for applications where operational temperatures may fluctuate, preventing binding and ensuring smooth rotation.
- High-Speed Capability: The combination of the lightweight nylon cage (HTN9) and the balanced internal geometry enables a high limiting speed of 28,000 rpm. This makes it an excellent choice for demanding, high-speed applications.
- Precision and Reliability: Manufactured to ABEC 1 precision standards with chrome steel rings and balls, this bearing offers consistent dimensional accuracy and high dynamic load capacity (873 lbf), ensuring reliable performance in critical applications.
629-RSHTN9/C3LT Bearing Typical Application Areas
The 629-RSHTN9/C3LT is versatile and finds use in a wide array of compact and high-speed machinery, including:
- Small Electric Motors: Ideal for fans, blowers, and power tools requiring reliable, sealed bearings.
- Precision Instruments: Used in medical devices, optical equipment, and measuring instruments where quiet operation and contamination control are paramount.
- Office Automation Equipment: Suitable for printers, scanners, and copiers.
- Material Handling Systems: Applicable in small conveyor rollers and pulleys.
