1316-K-M-C3 Bearing Product Overview & Core Advantages
The 1316-K-M-C3 is a double row angular contact ball bearing designed for exceptional performance in demanding industrial applications. This precision bearing features a tapered bore (1:12) for secure mounting on adapter sleeves or withdrawal sleeves, ensuring precise shaft fixation. Its double row design provides high rigidity and the ability to accommodate combined loads (substantial radial loads with moderate axial loads in both directions). Manufactured from high-grade chrome steel with a brass cage, it is optimized for reliable operation and long service life, making it an ideal choice for applications requiring high reliability and precision.
1316-K-M-C3 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance & Advantage |
|---|---|---|
| K | Tapered Bore (1:12) | Enables precise axial positioning and secure mounting on a tapered shaft or via adapter sleeves, facilitating easier installation and disassembly. |
| M | Brass Cage | Provides high strength and excellent guidance for the balls, contributing to stable operation and suitability for high-speed applications. |
| C3 | Greater than Normal Radial Internal Clearance | Accommodates thermal expansion in applications with high operating temperatures or where fits result in a reduction of internal clearance. |
1316-K-M-C3 Bearing Structural Features & Performance Benefits
High Rigidity and Load Capacity: The double row construction significantly increases the bearing's moment stiffness and its capacity to handle combined loads. This makes it exceptionally stable under complex loading conditions.
Optimized for Performance: The brass cage (M) ensures smooth ball guidance and is capable of withstanding high centrifugal forces, which is critical for achieving the bearing's limiting speed of 5,300 rpm. The C3 radial internal clearance is selected for applications prone to thermal expansion, preventing preload and potential seizure.
Precision Tapered Bore: The K designation indicates a tapered bore, which allows for micro-adjustments of the internal clearance during mounting and provides a very secure, interference fit on the shaft, eliminating creep.
Material Integrity: Constructed from chrome steel for both rings and balls, the bearing offers high fatigue life and durability under heavy loads.
