1319-K-M-C3 Bearing Product Overview & Core Advantages
The 1319-K-M-C3 is a double row angular contact ball bearing engineered for demanding applications requiring high rigidity and precise operation. Featuring a tapered bore (1:12) and C3 radial internal clearance, this precision bearing is designed to accommodate combined loads—significant radial forces alongside axial loads in both directions. Its robust double row design provides exceptional stiffness, making it ideal for machinery where shaft deflection must be minimized. Pre-lubricated for immediate operation and constructed from high-grade chrome steel with a brass cage, it delivers reliable performance in high-speed and high-load scenarios.
1319-K-M-C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1319 | Standard bearing series designation, indicating the bearing dimensions (95mm bore, 200mm OD, 45mm width). |
| K | Denotes a tapered bore with a 1:12 taper ratio, facilitating secure mounting on adapter sleeves. |
| M | Indicates the bearing is supplied with brass cage (machined window-type), offering high strength and excellent guidance at high speeds. |
| C3 | Specifies a greater than normal radial internal clearance, suitable for applications with thermal expansion or where interference fits are used. |
1319-K-M-C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball construction provides a rigid support system, effectively handling combined radial and axial loads from both directions. This makes it superior to single row bearings in applications with complex loading.
- Optimized for High-Speed Operation: The precision-machined brass cage (M) ensures stable ball guidance, reduces friction, and contributes to a high limiting speed of 4,300 rpm. The open design allows for efficient lubrication flow.
- Tapered Bore for Secure Mounting: The 1:12 tapered bore (K) enables precise and firm mounting on an adapter sleeve, ensuring a tight fit and simplifying installation and disassembly procedures.
- Controlled Internal Clearance: The C3 clearance is engineered for operational conditions where thermal expansion is a factor, preventing preload and ensuring smooth, reliable performance.
- Durable Material Construction: Manufactured from chrome steel rings and balls, the bearing offers high fatigue resistance and longevity. The combination of materials ensures consistent performance within a temperature range of -30°C to 110°C.
1319-K-M-C3 Bearing Typical Application Areas
This bearing is ideally suited for heavy-duty industrial machinery and precision equipment, including:
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment (e.g., conveyor pulleys)
- Vibrating Screens and Mining Machinery
- Agricultural Machinery
