1219J Bearing Product Overview & Core Advantages
The 1219J 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 it to simultaneously support substantial radial loads and bidirectional axial loads, making it an ideal solution for compact arrangements where space is limited. Manufactured with chrome steel rings and balls, this bearing offers excellent durability and is pre-lubricated for immediate use, ensuring long service life in demanding industrial environments.
1219J Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1219J | Basic bearing designation indicating double row angular contact ball bearing with specific bearing dimensions (95mm bore, 170mm OD) |
| Open (Seal Type) | No seals or shields, allowing for higher speed operation and relubrication capability |
| CN (Clearance) | Normal radial internal clearance suitable for most operating conditions |
| Lubricated | Factory pre-lubricated for immediate installation and operation |
1219J Bearing Structural Features & Performance Benefits
High Rigidity: The double row design provides exceptional stiffness, making this bearing ideal for applications requiring minimal deflection under load. The optimized contact angle distribution ensures stable performance even under heavy combined loads.
Superior Load Capacity: With a radial dynamic load rating of 14,332 lbf and radial static load rating of 6,075 lbf, this bearing can handle significant radial and bidirectional axial forces simultaneously, offering versatile load-carrying capability.
Optimized Performance: The steel cage construction ensures reliable operation at the limiting speed of 5,000 rpm, while the open design allows for efficient heat dissipation and potential relubrication in high-speed applications.
Precision Engineering: Manufactured with tight dimensional tolerances and CN radial internal clearance, this bearing delivers consistent performance and smooth operation across its operating temperature range of -30°C to 110°C.
