1216/C3 Bearing Product Overview & Core Advantages
The 1216/C3 is a double row angular contact ball bearing designed for applications requiring high rigidity and reliable performance under combined loads. Its metric design features a 80 mm bore and 140 mm outside diameter, providing a compact solution for space-constrained installations. With its C3 radial internal clearance, this bearing accommodates thermal expansion in demanding operating conditions, making it suitable for precision machinery requiring stable operation under varying temperatures.
1216/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| 1216 | Standard bearing designation indicating bearing dimensions: 80mm bore, 140mm OD, 26mm width | Standardized interchangeability and easy replacement |
| C3 | Radial internal clearance greater than normal | Accommodates thermal expansion, suitable for applications with temperature variations |
1216/C3 Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row construction provides superior stiffness compared to single row bearings, enabling precise positioning and reduced deflection under heavy loads.
Enhanced Load Capacity: Engineered to handle significant radial loads (8932 lbf dynamic rating) while accommodating moderate axial loads in both directions, making it ideal for combined loading applications.
Optimized Performance: The nylon cage ensures smooth operation at high speeds (limiting speed: 6,000 rpm) while reducing friction and heat generation. The open design allows for efficient lubrication management.
Precision Manufacturing: Manufactured from chrome steel with tight dimensional tolerances, ensuring consistent performance and long service life in demanding industrial environments.
