6300-2ZTN9/C3LT Bearing Product Overview & Core Advantages
The 6300-2ZTN9/C3LT is a single row deep groove ball bearing engineered for high performance in demanding applications. This shielded bearing is designed to primarily handle radial loads efficiently. Its key advantages include a compact design, high operational reliability, and suitability for high-speed applications. The combination of a nylon cage (TN9) and increased radial internal clearance (C3) ensures smooth operation and accommodates thermal expansion, making it a robust choice for various industrial uses.
6300-2ZTN9/C3LT Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Benefit |
|---|---|---|
| 2Z | Non-contact steel shields on both sides | Provides effective protection against contamination while maintaining high-speed capability and low friction. |
| TN9 | Cage made of glass fiber reinforced polyamide (Nylon) | Lightweight cage contributes to lower inertia, reduced friction, and excellent performance at high rotational speeds. |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in applications with high operating temperatures or heavy loads, preventing premature failure. |
| LT | Specialty high-temperature grease lubrication | Enables reliable operation across the specified temperature range (-30°C to 120°C) and extends service life. |
6300-2ZTN9/C3LT Bearing Structural Features & Performance Benefits
Optimized for High-Speed Operation: The nylon TN9 cage is a critical component that minimizes weight and friction, directly contributing to the bearing's high limiting speed of 22,000 rpm. This makes it an ideal high-speed bearing.
Robust Load Handling: Manufactured from chrome steel for both rings and balls, this bearing offers a dynamic load rating of 1821 lbf and a static load rating of 776 lbf, ensuring durability under significant radial loads.
Enhanced Operational Reliability: The C3 radial clearance provides a safety margin for thermal expansion, preventing binding and ensuring consistent performance. The 2Z shields protect the internal components from dust and debris, enhancing longevity in contaminated environments.
Maintenance-Free Service: Pre-lubricated with high-temperature grease (LT) and sealed with shields, this bearing is ready for use and requires no relubrication in many applications, reducing maintenance costs.
6300-2ZTN9/C3LT Bearing Typical Application Areas
The 6300-2ZTN9/C3LT is versatile and finds use in a wide range of industries and equipment, including:
- Electric Motors and Small Gearboxes
- Pumps and Compressors
- Material Handling Systems and Conveyors
- Agricultural Machinery
- Automotive Auxiliary Units (e.g., alternators, idler pulleys)
