1320-M Bearing Product Overview & Core Advantages
The 1320-M is a double row angular contact ball bearing designed for demanding industrial applications requiring high precision and robust performance. This metric bearing features an open design, enabling it to accommodate combined loads—significant radial forces alongside moderate axial loads in both directions. Its double row construction provides exceptional rigidity and stability, making it an ideal choice for applications where shaft deflection must be minimized. Manufactured from high-grade chrome steel with a brass cage, it offers reliable operation and is pre-lubricated for immediate use.
1320-M Bearing Model Code Explained, Specifications & Naming Convention
| Suffix / Prefix | Technical Meaning |
|---|---|
| 1320 | Standard bearing series designation, indicating the basic dimensions (100mm bore, 215mm OD, 47mm width). |
| -M | Indicates the bearing is supplied with brass cage (machined window-type). This cage material is suitable for high-speed applications and offers excellent durability. |
1320-M Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball design provides superior stiffness and enables the bearing to support substantial radial dynamic loads (32,175 lbf) and static loads (12,825 lbf), effectively handling combined loading conditions.
- Optimized for Performance: The brass cage (M suffix) ensures smooth operation at the limiting speed of 4,000 rpm, contributing to the bearing's high-speed capability. The CN radial internal clearance is the standard for normal operating conditions.
- Precision & Durability: Manufactured from chrome steel for both rings and balls, the bearing offers high wear resistance and long service life. The precise dimensional tolerances on the bore diameter and outside diameter ensure a reliable fit and consistent performance.
- Ready-to-Use Convenience: The bearing comes pre-lubricated, facilitating easy installation and immediate operation within a wide temperature range of -30°C to 110°C.
1320-M Bearing Typical Application Areas
This double row angular contact ball bearing is engineered for use in a variety of heavy-duty and precision machinery, including:
- Gearboxes and power transmission systems
- Industrial Pumps and Compressors
- Medium-duty Machine Tool spindles and components
- Material handling equipment such as Conveyors
- Various industrial machinery requiring robust radial load support
