312/C3 Bearing Product Overview & Core Advantages
The 312/C3 is a single row deep groove ball bearing designed for robust performance in a wide range of industrial applications. This metric bearing excels at handling primarily radial loads and offers high operational reliability. Its key advantages include a high radial dynamic load rating of 20,525 lbf, ensuring long service life under demanding conditions. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides consistent and precise operation. The specified C3 radial internal clearance makes it particularly suitable for applications where thermal expansion is a factor, ensuring optimal performance across its operating temperature range.
Model Code Breakdown
| Model Segment | Technical Meaning |
|---|---|
| 312 | Standard bearing series designation, indicating a metric single row deep groove ball bearing with a 60mm bore, 130mm OD, and 31mm width. |
| /C3 | Indicates a greater than normal radial internal clearance. This is critical for applications with potential thermal expansion, misalignment, or where a heavier interference fit is used. |
312/C3 Bearing Structural Features & Performance Benefits
- Open Design & High-Quality Materials: The open seal type allows for easy re-lubrication and is ideal for high-speed applications. All core components, including the rings, balls, and cage, are manufactured from chrome steel, providing excellent hardness, wear resistance, and durability.
- High Load Capacity: With a substantial radial dynamic load rating, this bearing is engineered to withstand significant stresses, contributing to a long operational lifespan and reduced maintenance frequency.
- Optimized for Thermal Conditions: The C3 clearance is a key performance feature, preventing binding and reducing friction-induced heat buildup in applications where operating temperatures cause dimensional changes.
- Standard Precision: Conforming to ABEC 1 (ISO P0) tolerance class, it ensures smooth and reliable running for a vast majority of industrial applications without the cost of ultra-high precision grades.
312/C3 Bearing Typical Application Areas
This versatile deep groove ball bearing is widely used across various sectors due to its robust construction and reliable performance. Common applications include:
- Electric Motors and Generators
- Industrial Gearboxes
- Agricultural Machinery
- Material Handling Equipment (e.g., conveyor pulleys)
- General Industrial Machinery requiring a dependable, standard-clearance bearing solution.
