1220/C3 Bearing Product Overview & Core Advantages
The 1220/C3 is a double row angular contact ball bearing designed for demanding industrial applications requiring high load capacity and operational reliability. This precision bearing excels at simultaneously handling significant combined loads, including radial forces and bidirectional axial loads, thanks to its optimized double-row ball and raceway design. Its open construction allows for versatile lubrication options, while the specified C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or where interference fits are used, ensuring stable performance under varying operational conditions.
1220/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 1220 | Basic bearing designation | Indicates bearing dimensions: 100mm bore, 180mm OD, 34mm width |
| /C3 | Radial internal clearance group | Specifies greater than normal clearance for thermal expansion compensation |
1220/C3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior stiffness and enables the bearing to handle higher radial loads and bidirectional axial loads compared to single row alternatives. With a dynamic load rating of 15,502 lbf and static load rating of 6,750 lbf, it delivers exceptional durability in heavy-duty applications.
Optimized Material Construction: Manufactured from chrome steel rings and balls with a stainless steel cage, this bearing offers excellent wear resistance and corrosion protection. The combination ensures reliable performance across the specified temperature range of -30°C to 110°C.
Speed & Lubrication Performance: The stainless steel cage contributes to stable operation at the limiting speed of 4,800 rpm, while the open seal type allows for optimal lubrication management based on specific application requirements.
