6312/W64 Bearing Product Overview & Core Advantages
The 6312/W64 is a single row deep groove ball bearing designed for exceptional performance in demanding industrial applications. Engineered as a metric bearing with an open design, it excels at handling primarily radial loads while also accommodating moderate axial loads in both directions. Its key advantages include a high limiting speed and reliable operation, enhanced by its integrated Soild Oil lubrication system, making it a robust and long-lasting solution for a wide range of machinery.
6312/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning | Benefit |
|---|---|---|
| 6312 | Standard designation for a single row deep groove ball bearing with a 60mm bore, 130mm OD, and 31mm width. | Defines the core bearing dimensions and type for interchangeability. |
| /W64 | Suffix indicating the bearing is pre-lubricated with Soild Oil (a polymer-based lubricant). | Provides maintenance-free operation, superior contamination resistance, and consistent lubrication over a wide temperature range. |
6312/W64 Bearing Structural Features & Performance Benefits
Optimized for Radial Load Capacity: The single row deep groove raceway geometry is precision-engineered to carry high radial dynamic (18,412 lbf) and static load ratings (11,735 lbf), ensuring durability under heavy loads.
High-Speed Capability: The combination of an open design, CN radial internal clearance, and a chrome steel cage contributes to a high limiting speed of 5,300 rpm, suitable for demanding rotational applications.
Maintenance-Free & Contamination Resistant: The integrated Soild Oil lubrication eliminates the need for re-lubrication, prevents lubricant wash-out, and offers excellent protection against contamination, significantly extending service life.
Precision & Reliability: Manufactured to ABEC 1 | ISO P0 tolerance class with tight dimensional tolerances, this bearing ensures consistent performance, smooth operation, and high reliability in general industrial applications.
6312/W64 Bearing Typical Application Areas
The 6312/W64 is ideally suited for a broad spectrum of industrial machinery where reliability and minimal maintenance are critical. Common applications include:
- Electric Motors and Generators
- Industrial Gearboxes and Transmission Systems
- Material Handling Equipment (conveyors, pulleys)
- Agricultural Machinery
- Ventilation Fans and Blowers
