1220J Bearing Product Overview & Core Advantages
The 1220J double row angular contact ball bearing is a precision bearing engineered for applications requiring high rigidity and reliable performance under combined loads. Its double row design enables simultaneous support of substantial radial loads and bidirectional axial loads, making it ideal for compact arrangements where space optimization is critical. Manufactured with chrome steel components and featuring optimized internal geometry, this bearing delivers exceptional dimensional stability and longevity in demanding industrial environments.
Model Code Detailed Breakdown
| Suffix Code | Technical Significance |
|---|---|
| J | Designates manufacturing tolerances and internal clearance conforming to standard specifications |
| Open | No sealing, optimized for lubrication management in controlled environments |
| CN | Standard radial internal clearance for general applications |
1220J Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row construction provides superior stiffness compared to single row bearings, effectively handling combined loads (radial and bidirectional axial) in compact bearing dimensions (100mm bore × 180mm OD × 34mm width).
Precision Engineering: Manufactured with chrome steel rings and balls with precise bore diameter tolerance (-0.02mm to 0) ensures consistent performance and extended service life.
Optimized Speed Performance: The steel cage construction and proper lubrication enable a limiting speed of 4,800 rpm, making it suitable for high-speed applications.
Reliable Operation: Pre-lubricated and featuring standard CN clearance, the bearing offers immediate installation readiness and stable operation across a temperature range of -30°C to 110°C.
1220J Bearing Typical Application Areas
- Industrial Gearboxes and power transmission systems
- Machine Tool Spindles requiring high precision and rigidity
- Material Handling Equipment such as conveyor systems
- Pump and Compressor assemblies
- Agricultural Machinery and construction equipment
