629-2RSLTN9/C2ELT Bearing Product Overview & Core Advantages
The 629-2RSLTN9/C2ELT is a sealed single row deep groove ball bearing engineered for high reliability in demanding applications. This metric bearing excels at handling radial loads and offers robust performance due to its precision construction. Its compact design, featuring a 9 mm bore and 26 mm outside diameter, makes it ideal for applications where space is limited but performance cannot be compromised. Manufactured to ABEC 1 | ISO P0 tolerance standards, it ensures consistent operation and is pre-lubricated for immediate use, offering a versatile solution for a wide range of industrial equipment.
629-2RSLTN9/C2ELT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 629 | Basic series designation for a single row deep groove ball bearing. |
| -2RSL | Features contact seals on both sides. The "RS" denotes rubber seals, and the "L" indicates a light preload of grease, providing excellent protection against contamination and retaining lubrication. |
| TN9 | Indicates a glass fiber reinforced nylon cage (polyamide). This cage design contributes to quiet operation, low friction, and is suitable for high-speed applications. |
| /C2 | Specifies a radial internal clearance that is smaller than normal (C2 group). This is selected for applications requiring precise shaft positioning and where operating temperatures are expected to be stable. |
| ELT | Signifies the use of a specific, high-quality extreme low temperature (ELT) grease. This lubrication ensures reliable performance across the specified temperature range of -30°C to 120°C. |
629-2RSLTN9/C2ELT Bearing Structural Features & Performance Benefits
The performance of the 629-2RSLTN9/C2ELT is a direct result of its carefully selected components and design:
- Superior Sealing & Contamination Resistance: The double-sided contact seals (2RSL) provide a highly effective barrier against dust, moisture, and other contaminants. This significantly extends the bearing's service life by protecting the chrome steel rings and balls from premature wear.
- Optimized High-Speed Capability: The lightweight and robust nylon TN9 cage minimizes centrifugal forces and friction, allowing for a high limiting speed of 28,000 rpm. This makes it an excellent choice for high-speed applications.
- Precision & Stability: Manufactured to ABEC 1 precision with a C2 clearance, this bearing offers smooth running and accurate rotational performance, which is critical for reducing vibration and noise.
- Ready-to-Use & Long-Lasting Lubrication: Pre-lubricated with ELT grease, the bearing is maintenance-free for its entire service life in many applications, simplifying installation and reducing long-term maintenance costs.
629-2RSLTN9/C2ELT Bearing Typical Application Areas
The 629-2RSLTN9/C2ELT is a versatile component suited for a wide array of precision machinery and devices, including:
- Small Electric Motors (e.g., cooling fans, servo motors)
- Office Automation Equipment (printers, scanners, copiers)
- Medical Devices and Dental Handpieces
- Precision Instrumentation and Measurement Tools
- Textile Machinery Spindles
- Food Processing Equipment (where the seal and grease are compatible)
