1305 C3 Bearing Product Overview & Core Advantages
The 1305 C3 is a double row angular contact ball bearing designed for applications requiring high rigidity and reliable performance under combined loads. Featuring an open design with precision C3 radial internal clearance, this metric bearing delivers optimal performance in demanding environments. Its compact 17mm width and robust construction make it ideal for space-constrained applications where both radial and axial load capacity are critical requirements.
1305 C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Impact |
|---|---|---|
| 1305 | Standard metric series designation (25mm bore, 62mm OD) | Defines dimensional compatibility |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in high-temperature applications |
1305 C3 Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row construction provides superior stiffness compared to single row bearings, making it ideal for applications requiring precise shaft positioning and minimal deflection.
Enhanced Load Capacity: Engineered to handle significant radial loads (4275 lbf dynamic rating) while accommodating moderate axial loads in both directions, offering versatile combined load capability.
Optimized Performance: The nylon cage ensures smooth operation at speeds up to 15,000 rpm, while the C3 clearance prevents binding during thermal expansion, maintaining consistent performance across the operating temperature range.
Precision Engineering: Manufactured from chrome steel with tight dimensional tolerances, ensuring reliable operation in precision machinery and industrial equipment.
