1303 C/2 Bearing Product Overview & Core Advantages
The 1303 C/2 is a double row angular contact ball bearing designed for applications requiring high rigidity and precision. This metric bearing features an open design, allowing for versatile lubrication options. Its primary advantage lies in its ability to support significant combined loads, handling both radial forces and bidirectional axial loads simultaneously. Constructed with chrome steel rings and balls, and a durable brass cage, it delivers reliable performance in demanding environments. The bearing is pre-lubricated and operates efficiently within a temperature range of -30°C to 110°C, making it suitable for high-reliability applications where consistent performance is critical.
1303 C/2 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| C/2 | Indicates a specific internal design and radial internal clearance group (CN standard clearance). This optimized clearance ensures stable operation under normal load and speed conditions. |
1303 C/2 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row construction provides superior rigidity and enables the bearing to support substantial radial dynamic load ratings (2858 lbf) and static load ratings (765 lbf), effectively managing complex combined loads.
- Optimized Cage Design: The brass cage ensures excellent dimensional stability and low wear, contributing to smooth operation and extended service life, even at the limiting speed of 20,000 rpm.
- Precision Engineering: Manufactured with tight tolerances on the bore diameter (17 mm), outside diameter (47 mm), and width (14 mm), guaranteeing precise fit and alignment in assemblies.
- Versatile Lubrication: The open seal type allows for the application of various lubricants, enabling customization based on specific operational requirements such as speed, temperature, and load.
1303 C/2 Bearing Typical Application Areas
- Precision Machine Tools: Spindles and feed drives requiring high rigidity and accuracy.
- Industrial Gearboxes: Supporting shafts subject to combined radial and axial loads.
- Electric Motors: Used in motor designs demanding high-speed capability and reliable performance.
- Material Handling Equipment: Conveyor systems and pulleys where robust load support is essential.
- General Industrial Machinery: Pumps, compressors, and other rotating equipment requiring durable double row ball bearings.
