6312-2Z/C3LHT23 Bearing Product Overview & Core Advantages
The 6312-2Z/C3 is a single row deep groove ball bearing designed for robust performance in demanding industrial applications. This shielded bearing offers reliable operation and is characterized by its ability to accommodate radial loads and moderate axial loads in both directions. Its C3 radial internal clearance makes it particularly suitable for applications where thermal expansion is a concern, ensuring stable performance across a wide temperature range. With an ABEC 1 (ISO P0) tolerance class, it provides excellent value for general precision requirements.
6312-2Z/C3LHT23 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Advantage |
|---|---|---|
| 6312 | Basic bearing designation (60mm bore, 130mm OD, 31mm width) | Standard bearing dimensions for easy interchangeability |
| 2Z | Non-contact steel shields on both sides | Effective contamination protection with minimal friction increase |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in high-temperature applications |
6312-2Z/C3LHT23 Bearing Structural Features & Performance Benefits
Optimized Load Capacity: The single row deep groove raceway geometry enables the bearing to handle significant radial dynamic load rating of 18,412 lbf while also accommodating axial loads. This makes it versatile for various loading conditions.
Shielded Protection: The 2Z shields provide effective sealing against contaminants while maintaining low operating torque, contributing to the limiting speed of 5,300 rpm.
Thermal Stability: The C3 clearance ensures reliable operation across the specified temperature range of -30°C to 120°C, preventing binding due to thermal expansion.
Material Excellence: Constructed entirely from chrome steel for rings, balls, and cage, ensuring consistent hardness, wear resistance, and dimensional stability under load.
