1204C3 Bearing Product Overview & Core Advantages
The 1204C3 is a double row angular contact ball bearing designed for applications requiring high rigidity and reliable performance under combined loads. This precision bearing efficiently handles significant radial loads and bidirectional axial loads simultaneously, thanks to its optimized contact angle and double row design. Its compact construction, featuring a 20 mm bore and 47 mm outside diameter, makes it ideal for space-constrained, high-precision assemblies. The C3 radial internal clearance ensures stable operation across a wider temperature range and under varying operational conditions, providing enhanced versatility for demanding industrial environments.

| 1204 | Basic bearing designation indicating bearing size (20mm bore, 47mm OD) |
| C3 | Radial internal clearance greater than normal, suitable for applications with thermal expansion or heavy loads |
1204C3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row construction provides superior radial and axial stiffness, enabling the bearing to withstand substantial combined loads without compromising performance. This design ensures stable operation even under demanding conditions.
Optimized Material Selection: Constructed from chrome steel for both rings and balls, the bearing delivers excellent wear resistance and durability. The nylon cage contributes to smooth operation at high speeds while reducing friction and noise.
Enhanced Operational Range: With a C3 clearance classification, this bearing accommodates thermal expansion and shaft deflections more effectively than standard clearance bearings. The limiting speed of 20,000 rpm makes it suitable for high-speed applications, while the wide temperature range (-30° to 110°C) ensures reliable performance across various operating environments.
1204C3 Bearing Typical Application Areas
- Electric Motors and Industrial Gearboxes requiring high-speed operation and combined load capacity
- Machine Tool Spindles and Precision Machinery demanding high rigidity and accuracy
- Pumps and Compressors operating under varying thermal conditions
- Material Handling Equipment and Conveyor Systems requiring reliable bearing performance
