1318 M C/3 Bearing Product Overview & Core Advantages
The 1318 M C/3 is a double row angular contact ball bearing designed for demanding applications requiring high rigidity and precision. This open-type bearing is engineered to accommodate combined loads, simultaneously handling significant radial forces and moderate axial loads in both directions. Its compact double row design provides a robust and stable solution for machinery where space constraints and operational reliability are critical. Manufactured from high-grade chrome steel and featuring a durable brass cage, this bearing is built for longevity and consistent performance in a wide temperature range from -30°C to 110°C.
1318 M C/3 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| M | Indicates the use of brass (machined) cage, which offers excellent strength and is suitable for high-speed applications. |
| C/3 | Specifies the radial internal clearance group. C3 clearance is greater than the standard CN group, making it suitable for applications with thermal expansion or where interference fits are used. |
1318 M C/3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing construction provides superior rigidity and stability compared to single row designs. This enables the bearing to support substantial radial dynamic load ratings of 26,325 lbf and effectively manage combined loads.
- Optimized for Precision: Manufactured with tight dimensional tolerances on the bore diameter (90 mm) and outside diameter (190 mm), ensuring precise fit and alignment in the housing.
- High-Speed Capability: The robust brass cage (M) ensures smooth operation and guidance of the balls at the specified limiting speed of 4,500 rpm, contributing to reliable high-speed performance.
- Versatile Operating Range: The open design allows for customized lubrication regimes, while the C3 radial clearance accommodates thermal expansion, making it suitable for a wide range of industrial environments.
1318 M C/3 Bearing Typical Application Areas
This bearing is ideal for heavy-duty and precision machinery, including:
- Industrial Gearboxes
- Machine Tool Spindles
- Pumps and Compressors
- Material Handling Equipment
- Electric Motors
