1205 C/3 Bearing Product Overview & Core Advantages
The 1205 C/3 is a metric double row angular contact ball bearing designed for applications requiring high precision and reliable performance. This bearing excels at handling combined loads, simultaneously supporting significant radial forces and moderate axial loads in both directions. Its compact design, featuring a 15 mm width, makes it ideal for space-constrained assemblies. Manufactured with chrome steel rings and balls, and a nylon cage, it offers excellent durability and smooth operation, suitable for demanding industrial environments.
1205 C/3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1205 | Basic designation indicating a double row angular contact ball bearing with a 25 mm bore diameter and 52 mm outside diameter. |
| C | Designates the specified radial internal clearance group. In this case, 'C' corresponds to the CN clearance (Normal Group). |
| 3 | Indicates the bearing is lubricated with a standard grease from the manufacturer, suitable for the specified temperature range. |
1205 C/3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior rigidity and stability compared to single row bearings, enabling it to handle higher radial dynamic load ratings (3218 lbf) and resist operational deformations effectively.
Optimized for Precision: Manufactured with tight dimensional tolerances on the bore diameter and outside diameter, this bearing ensures precise shaft and housing fits, which is critical for applications requiring high running accuracy.
Enhanced Operational Performance: The lightweight nylon cage minimizes centrifugal forces, contributing to lower friction and enabling a high limiting speed of 18,000 rpm. The standard pre-lubrication facilitates immediate start-up and reduces maintenance needs.
1205 C/3 Bearing Typical Application Areas
The 1205 C/3 is widely used in various precision machinery and industrial equipment, including:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment
- Precision Agricultural Machinery
