1313KC3 Bearing Product Overview & Core Advantages
The 1313KC3 is a metric double row angular contact ball bearing engineered for demanding industrial applications requiring high load capacity and robust performance. Featuring a tapered bore (1:12) and C3 radial internal clearance, this bearing is specifically designed to accommodate combined radial loads effectively. Its double-row ball construction provides exceptional rigidity and stability, making it suitable for machinery where precision and reliability are critical. Pre-lubricated for immediate use, it offers reliable operation within a broad temperature range from -30°C to 110°C.
1313KC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1313 | Standard bearing series designation indicating specific bore diameter (65 mm), outside diameter (140 mm), and width (33 mm) dimensions. |
| K | Indicates a tapered bore with a 1:12 ratio, facilitating precise mounting and dismounting on tapered shafts. |
| C3 | Specifies a greater radial internal clearance than normal, suitable for applications with thermal expansion or where interference fits are used. |
1313KC3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact ball bearing design provides superior stiffness and enables the bearing to support significant radial dynamic loads (14,625 lbf) and radial static loads (5,738 lbf). This makes it ideal for applications subject to heavy or fluctuating loads.
Precision & Durability: Manufactured from chrome steel for both rings and balls, the bearing ensures high strength and wear resistance. The nylon cage contributes to smooth operation, reduced friction, and is suitable for the specified limiting speed.
Optimized for Specific Mounting: The tapered bore allows for a secure, interference fit on a matching tapered shaft adapter, ensuring minimal slippage and precise alignment under load.
Ready-to-Use Lubrication: The bearing comes pre-lubricated, facilitating easy installation and providing immediate protection against wear, contributing to a long service life.
