1220-M-C3 Bearing Product Overview & Core Advantages
The 1220-M-C3 is a double row angular contact ball bearing designed for demanding applications requiring high load capacity and operational reliability. This precision bearing excels at simultaneously supporting substantial combined loads—both radial and axial forces—within a compact design envelope. Its optimized internal geometry and robust construction contribute to exceptional high rigidity, making it an ideal choice for machinery where shaft stability is critical. The bearing is pre-lubricated for immediate use and features a generous C3 radial internal clearance, accommodating thermal expansion in high-speed or high-temperature environments.
1220-M-C3 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 1220 | Standard bearing series designation, indicating the bearing dimensions (100mm bore, 180mm OD, 34mm width). |
| M | Indicates a brass cage (machined). This cage type offers high strength, excellent guidance, and is suitable for high-speed applications and demanding operating conditions. |
| C3 | Specifies a radial internal clearance greater than the Normal (CN) group. This clearance is ideal for applications with expected thermal expansion, such as in high-speed operations or where adjacent components have different thermal growth rates. |
1220-M-C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and optimized contact angles provide superior stiffness, enabling the bearing to handle significant combined loads with minimal deflection, ensuring precise shaft positioning.
- Optimized for Performance: The machined brass cage ensures stable ball guidance and low friction, contributing to smooth operation and a high limiting speed of 4,800 rpm. This makes it a capable high-speed bearing for many industrial applications.
- Robust Material Construction: Manufactured from chrome steel for both rings and balls, the bearing delivers high fatigue life and durability under continuous operation.
- Pre-lubricated & Ready-to-Use: Factory-applied lubrication simplifies installation and provides immediate protection, reducing initial setup time.
