1212C3 Bearing Product Overview & Core Advantages
The 1212C3 is a double row angular contact ball bearing designed for demanding applications requiring high rigidity and reliable performance under combined loads. Its metric design features a 60 mm bore and 110 mm outside diameter, providing a compact solution for space-constrained assemblies. This precision bearing is engineered to handle significant radial loads while accommodating axial loads in both directions, making it an ideal choice for applications where stability and accuracy are paramount. The C3 radial internal clearance ensures optimal performance in applications with thermal expansion or where interference fits are used.
1212C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Implication |
|---|---|---|
| 1212 | Standard bearing series designation | Defines basic dimensions: 60mm bore, 110mm OD, 22mm width |
| C3 | Radial internal clearance greater than normal | Accommodates thermal expansion and interference fits |
1212C3 Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row construction provides superior stiffness compared to single row bearings, enabling precise shaft positioning and reduced deflection under heavy loads.
Enhanced Load Capacity: Engineered to handle combined radial and axial loads simultaneously, with a dynamic load rating of 7020 lbf and static load rating of 2745 lbf.
Optimized Performance: The nylon cage ensures smooth operation at limiting speeds up to 8,000 rpm, while the open design allows for customized lubrication strategies.
Premium Materials: Manufactured from chrome steel for both rings and balls, providing excellent wear resistance and durability across a temperature range of -30° to 110°C.
