6203-2Z/C2LHT23 Bearing Product Overview & Core Advantages
The 6203-2Z/C2LHT23 is a metric single row deep groove ball bearing designed for exceptional performance in demanding applications. This shielded bearing features a C2 radial internal clearance and is manufactured to ABEC 1 | ISO P0 tolerance class, ensuring reliable operation and precise rotation. Its core advantages include robust radial load capacity and the convenience of being pre-lubricated for long-term, maintenance-free operation in a wide temperature range, making it an ideal choice for general industrial machinery requiring high reliability.
6203-2Z/C2LHT23 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6203 | Standard deep groove ball bearing series with 17mm bore, 40mm OD, 12mm width. |
| 2Z | Bearing is equipped with non-contact shields on both sides, providing effective protection against contaminants while allowing for high-speed operation. |
| C2 | Specifies a radial internal clearance smaller than the Normal (CN) group. This is beneficial for applications requiring precise shaft positioning and reduced noise. |
| LHT23 | Indicates the bearing is pre-lubricated with a specific high-temperature grease, suitable for the specified operating temperature range of -30°C to 120°C. |
6203-2Z/C2LHT23 Bearing Structural Features & Performance Benefits
- Optimized Load Handling: The single row deep groove raceway design enables the bearing to carry significant radial loads and moderate axial loads in both directions, providing versatile load support.
- Shielded Protection: The 2Z non-contact steel shields effectively retain grease and exclude larger particulate contaminants, enhancing bearing life and enabling a maintenance-free design in many environments.
- Precision & Stability: Manufactured to ABEC 1 precision with a C2 internal clearance, this bearing offers smooth, low-vibration, and low-noise operation, which is critical for the smooth running of motors and precision mechanisms.
- Ready-to-Install: Pre-lubricated with LHT23 grease, the bearing is immediately operational upon installation, reducing assembly time and ensuring optimal performance from the start across its full temperature range.
6203-2Z/C2LHT23 Bearing Typical Application Areas
