1217 C/3 Bearing Product Overview & Core Advantages
The 1217 C/3 is a double row angular contact ball bearing engineered for applications requiring exceptional rigidity and capacity to handle combined loads. This precision bearing features an open design and is pre-lubricated, making it suitable for high-reliability industrial environments. Its compact bearing dimensions (85mm bore, 150mm OD, 28mm width) provide a space-saving solution without compromising performance, offering robust support for radial and bidirectional axial forces.
1217 C/3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1217 | Standard bearing designation indicating bore diameter (85mm) and size series |
| C | Specific internal design and contact angle optimized for combined loading |
| 3 | Radial internal clearance designation (CN group - normal clearance) |
1217 C/3 Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row configuration provides superior stiffness compared to single row bearings, minimizing deflection under heavy combined loads.
Enhanced Load Capacity: Engineered to simultaneously withstand significant radial loads (10,980 lbf dynamic rating) and bidirectional axial loads, making it ideal for complex loading conditions.
Optimized Material Selection: Constructed with chrome steel rings and balls combined with a stainless steel cage for durability and corrosion resistance in demanding environments.
Precision Performance: Manufactured with tight dimensional tolerances and CN clearance for consistent operation in precision applications.
