1318-KM C/3 Bearing Product Overview & Core Advantages
The 1318-KM C/3 is a double row angular contact ball bearing designed for demanding applications requiring high load capacity and rigidity. This metric bearing features a tapered bore (1:12) for precise mounting and secure shaft fixation. Its double row design enables it to support significant combined loads—handling substantial radial forces and axial loads in both directions simultaneously. Manufactured from high-grade chrome steel and fitted with a durable brass cage, this bearing is engineered for high precision and reliable performance in industrial machinery. The open design allows for custom lubrication strategies, making it suitable for systems with centralized lubrication.
1318-KM C/3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1318 | Standard bearing series designation, indicating the core dimensions (90mm bore, 190mm OD). |
| KM | Indicates a tapered bore (1:12) and a withdrawal sleeve is required for mounting on a cylindrical shaft. |
| C/3 | Specifies the internal radial clearance group. C3 denotes a clearance greater than normal (CN), suitable for applications with thermal expansion or where interference fits are used. |
1318-KM C/3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball construction provides a robust, compact solution that delivers superior stiffness and can handle high radial dynamic loads (26,325 lbf) and static loads (9,900 lbf).
- Combined Load Performance: Engineered to accommodate combined radial and bidirectional axial loads efficiently, making it ideal for complex load scenarios.
- Tapered Bore for Secure Mounting: The 1:12 taper allows for precise axial positioning and a tight, slip-free fit on the shaft when used with an adapter sleeve, enhancing operational reliability.
- Optimized for Performance: The brass cage ensures stability at the specified limiting speed (4,500 rpm), while the C3 internal clearance accommodates thermal expansion in demanding operating conditions.
- Material Integrity: Components made from chrome steel offer high wear resistance and durability, supporting a wide operating temperature range from -30°C to 110°C.
