1204 C/2 Bearing Product Overview & Core Advantages
The 1204 C/2 is a double row angular contact ball bearing designed for applications requiring high precision and reliable performance. This metric bearing features an open design without seals, enabling optimal lubrication access and making it ideal for systems where external lubrication is provided. Its double row construction provides superior rigidity and the ability to handle combined loads (radial and axial loads) simultaneously. With a bore diameter of 20 mm and compact width of 14 mm, it offers a space-saving solution without compromising on load capacity or performance.
1204 C/2 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1204 | Standard bearing designation indicating 20mm bore diameter, 47mm outside diameter, and 14mm width |
| C | Specific internal design and contact angle optimized for angular contact applications |
| /2 | Indicates specific radial internal clearance group (CN clearance in this case) |
1204 C/2 Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row ball bearing configuration provides enhanced stiffness and stability, making it suitable for applications requiring precise shaft positioning and minimal deflection under load.
Superior Load Capacity: Engineered to handle combined radial and axial loads effectively, with a dynamic load rating of 2858 lbf and static load rating of 765 lbf, ensuring reliable performance in demanding conditions.
Optimized Material Selection: Constructed with chrome steel rings and balls for durability and wear resistance, combined with a nylon cage that reduces friction and enables smooth operation at the limiting speed of 20,000 rpm.
Precision Engineering: Features tight dimensional tolerances with bore diameter tolerance of -0.01mm to 0 and CN radial internal clearance, providing consistent performance in precision applications.
Temperature Resilience: Operates effectively within a temperature range of -30°C to 110°C, making it suitable for various industrial environments.
