6312-2RS1/C4/R806 Bearing Product Overview & Core Advantages

The 6312-2RS1/C4 is a sealed deep groove ball bearing designed for robust performance in demanding applications. As a metric single row bearing, it excels at handling primarily radial loads and offers reliable operation. A key feature is its C4 radial internal clearance, which is larger than standard, making it particularly suitable for applications involving thermal expansion, such as in electric motors. The integral 2RS1 rubber seals on both sides effectively protect against contamination, ensuring long service life and making it a maintenance-free solution for a wide range of industrial machinery.

6312-2RS1/C4/R806 Bearing Model Code Explained, Specifications & Naming Convention

Model Segment Technical Meaning
6312 Basic bearing code: 312 series with a 60 mm bore diameter and 130 mm outside diameter.
2RS1 Contact Rubber Seals on both sides. Provides excellent protection against dust and moisture ingress.
/C4 Radial Internal Clearance group C4. This is a larger-than-normal clearance, ideal for applications with significant temperature gradients.
/R806 Manufacturer-specific designation, typically referring to a specific production batch or packaging.

6312-2RS1/C4/R806 Bearing Structural Features & Performance Benefits

  • Robust Construction & High Load Capacity: Manufactured from chrome steel for both rings and balls, this bearing offers a high radial dynamic load rating of 18,412 lbf and a static load rating of 11,735 lbf, ensuring durability under heavy loads.
  • Optimized Internal Clearance: The C4 clearance is a critical feature that accommodates shaft and housing fits where interference is used, and compensates for differential thermal expansion between the shaft and housing, preventing premature failure.
  • Enhanced Contamination Protection: The 2RS1 rubber seals provide a high degree of sealing effectiveness, protecting the bearing's internal components from contaminants and retaining lubricant, which is essential for longevity in harsh environments.
  • Precision & Reliability: Built to ABEC 1 | ISO P0 tolerance class, it guarantees consistent performance and interchangeability, making it a reliable choice for general industrial use.

6312-2RS1/C4/R806 Bearing Typical Application Areas

The 6312-2RS1/C4 is a versatile component found in numerous industrial sectors. Its combination of sealing, high load capacity, and C4 clearance makes it ideal for:

  • Electric Motors and Generators (to handle thermal expansion)
  • Industrial Gearboxes and Transmissions
  • Material Handling Equipment (conveyors, pulleys)
  • Agricultural Machinery
  • Pumps and Fans
  • General machinery requiring a reliable, sealed ball bearing solution.
