6203-2ZTN9/C3LHT23 Bearing Product Overview & Core Advantages
The 6203-2ZTN9/C3LHT23 is a single row deep groove ball bearing engineered for high-performance industrial applications. This shielded bearing offers reliable radial load capacity and is characterized by its precision construction and optimized internal geometry. Its design ensures smooth operation and long service life, making it a robust and dependable choice for machinery requiring consistent performance under standard operating conditions. The bearing is supplied with a specific internal clearance and cage type, ready for integration into various mechanical systems.
6203-2ZTN9/C3LHT23 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6203 | Standard bearing series designation, indicating a metric single row deep groove ball bearing with a 17mm bore, 40mm OD, and 12mm width. |
| 2Z | Signifies that the bearing is shielded on both sides. These non-contact steel shields protect the internal components from large particulate contaminants while minimizing friction. |
| TN9 | Indicates the use of a glass fiber reinforced polyamide (Nylon) cage. This cage design is lightweight, promotes smooth operation at high speeds, and offers excellent strength and corrosion resistance. |
| C3 | Specifies a greater than normal radial internal clearance. This is suitable for applications with thermal expansion concerns or where interference fits are used. |
| LHT23 | This suffix denotes the specific high-temperature grease used for lubrication. It is designed for a temperature range of -30°C to 120°C, providing stable performance across a wide operating window. |
6203-2ZTN9/C3LHT23 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from chrome steel for both rings and balls, this bearing provides high hardness and wear resistance, supporting a dynamic load rating of 2147 lbf and a static load rating of 1079 lbf.
- Effective Contamination Protection: The double-shielded (2Z) design effectively prevents the ingress of coarse contaminants, extending bearing life and reducing the need for maintenance in dusty or dirty environments.
- Optimized High-Speed Performance: The lightweight and robust TN9 nylon cage minimizes centrifugal forces and ensures stable guidance of the balls, contributing to a high limiting speed of 17,000 rpm.
- Precision and Reliability: Manufactured to ABEC 1 | ISO P0 tolerance class, this bearing ensures consistent dimensional accuracy and running performance for a wide range of general-purpose applications.
- Pre-Lubricated for Long Life: Filled with LHT23 grease, the bearing is lubricated for life under normal operating conditions, offering a maintenance-free solution and reliable operation within its specified temperature range.
6203-2ZTN9/C3LHT23 Bearing Typical Application Areas
This versatile deep groove ball bearing is commonly specified for use in:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Material Handling Equipment (e.g., conveyor rollers)
- Agricultural Machinery
- Pumps and Fans
- General Industrial Machinery requiring reliable radial load support
