6312-2RS1/C3LHT64 Bearing Product Overview & Core Advantages
The 6312-2RS1/C3LHT64 is a sealed single row deep groove ball bearing engineered for demanding industrial applications. This metric bearing features robust construction with chrome steel components, providing excellent durability and wear resistance. Its key advantages include the ability to handle significant radial dynamic loads up to 18,412 lbf while maintaining stable operation. The C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or where interference fits are used. With its sealed design and wide operating temperature range from -30°C to 120°C, this bearing offers reliable performance in various environmental conditions.
Model Code Detailed Breakdown

| 12 | Bore diameter: 60 mm | Standard shaft size compatibility |
| 2RS1 | Contact rubber seals on both sides | Superior contamination protection and grease retention |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion and interference fits |
| LHT64 | High temperature grease (-40°C to +150°C) | Extended service life in high temperature environments |
6312-2RS1/C3LHT64 Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The optimized raceway design enables efficient handling of both radial loads and moderate axial loads in either direction, providing versatile load-bearing capabilities.
Contact Rubber Seals (2RS1): These high-performance seals offer excellent protection against contaminants while effectively retaining lubricant, significantly extending bearing service life in harsh environments.
Chrome Steel Construction: All critical components including rings, balls, and cage are manufactured from high-grade chrome steel, ensuring consistent performance and resistance to wear under demanding conditions.
Optimized Internal Clearance (C3): The increased radial clearance accommodates differential thermal expansion between bearing components and housing, preventing premature failure in applications with temperature variations.
High-Temperature Grease (LHT64): Pre-lubricated with specialized grease that maintains stable viscosity across a wide temperature range, supporting continuous operation up to 120°C.
