6312-2RS1/C3LHT23 Bearing Product Overview & Core Advantages
The 6312-2RS1/C3LHT23 is a sealed single row deep groove ball bearing engineered for robust performance in demanding industrial applications. This metric bearing is characterized by its ability to handle significant radial loads while offering operational reliability. Its sealed construction provides excellent contamination protection, making it a low-maintenance solution. Manufactured to ABEC 1 | ISO P0 tolerance standards, it ensures consistent performance and is suitable for a wide operating temperature range from -30°C to 120°C, compliant with ROHS and REACH directives.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6312 | Basic series designation, indicating a medium-duty single row deep groove ball bearing with a 60mm bore, 130mm OD, and 31mm width. |
| 2RS1 | Contact seals on both sides, providing superior protection against contaminants and retaining lubricant. |
| C3 | Greater than normal radial internal clearance, suitable for applications with thermal expansion or where interference fits are used. |
| LHT23 | Indicates the bearing is pre-lubricated with a specific high-temperature grease suitable for the stated temperature range. |
6312-2RS1/C3LHT23 Bearing Structural Features & Performance Benefits
This bearing's performance is derived from its precision construction. The single row deep groove raceway geometry is optimized for high radial load capacity, with a dynamic rating of 18412 lbf and a static rating of 11735 lbf. The use of chrome steel for all critical components (rings, balls, cage) ensures high durability and resistance to wear. The 2RS1 contact seals are a key feature, effectively shielding the internal components from dust, moisture, and other contaminants, thereby extending service life and enabling maintenance-free operation. The C3 radial internal clearance provides operational stability in applications prone to thermal expansion. With a limiting speed of 5,300 rpm, it offers reliable performance for a wide range of industrial speeds.
