6301/C3MT Bearing Product Overview & Core Advantages
The 6301/C3MT is a single row deep groove ball bearing engineered for exceptional performance in demanding industrial applications. This metric bearing is characterized by its open design and C3 radial internal clearance, making it ideally suited for applications with thermal expansion or where interference fits are used. Its primary advantage lies in its ability to handle significant radial loads while also accommodating moderate axial loads in both directions. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers reliable, cost-effective precision for a wide range of machinery.
6301/C3MT Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning | Benefit |
|---|---|---|
| 6301 | Standard designation for a single row deep groove ball bearing with a 12mm bore, 37mm OD, and 12mm width. | Defines the core bearing dimensions and type. |
| /C3 | Specifies a radial internal clearance greater than normal (CN). | Prevents binding in applications prone to thermal expansion or where tight fits are used, ensuring smooth operation. |
| MT | Indicates the bearing is supplied with a high-quality, standard industrial lubricant (grease). | Provides immediate, ready-to-install operation with initial lubrication, reducing setup time. |
6301/C3MT Bearing Structural Features & Performance Benefits
- Optimized Load Capacity: The single row deep groove raceway geometry is designed to support high radial dynamic load ratings (2181 lbf) and static loads (944 lbf), while also effectively managing bidirectional axial loads.
- C3 Internal Clearance: The greater-than-normal internal clearance provides operational reliability in environments with elevated temperatures or where shaft and housing fits create a reduction in innate clearance.
- High-Speed Capability: With a limiting speed of 20,000 rpm, this bearing is suitable for a variety of high-speed applications. The precision-ground chrome steel components and robust cage contribute to stable rotation.
- Precision & Durability: Manufactured from high-grade chrome steel for both rings and balls, and conforming to ABEC 1 (ISO P0) tolerances, this bearing ensures consistent performance, low noise, and long service life.
- Pre-Lubricated: The inclusion of MT lubricant offers immediate protection against wear and corrosion, simplifying the installation process.
6301/C3MT Bearing Typical Application Areas
The 6301/C3MT is a versatile component found in numerous industrial sectors, including:
- Electric Motors and Small Gearboxes
- Material Handling Equipment (e.g., conveyor rollers)
- Agricultural Machinery
- Pumps and Fans
- Automotive Components (e.g., alternators, idler pulleys)
- General Industrial Machinery requiring a reliable, standard-sized ball bearing.
