1319K Bearing Product Overview & Core Advantages
The 1319K double row angular contact ball bearing is a precision bearing engineered for applications requiring high rigidity and combined load capacity. Featuring a tapered bore (1:12) for secure shaft mounting, this bearing excels at simultaneously handling substantial radial loads. Its double row design provides exceptional stiffness and rotational accuracy, making it an ideal choice for demanding industrial machinery where reliability and performance are critical. The bearing comes pre-lubricated for immediate service and is manufactured from high-grade chrome steel for extended service life.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 1319K | Basic bearing designation indicating the bearing size and series (95mm bore, 200mm OD). |
| K | Denotes a tapered bore with a 1:12 ratio, designed for precise interference fit on adapter sleeves or withdrawal sleeves. |
| (No Seal Suffix) | Open construction, allowing for high-speed operation and customizable re-lubrication schemes. |
| (Implied) | Standard CN radial internal clearance and pre-lubrication for general operating conditions. |
1319K Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and robust construction provide superior stiffness, enabling the bearing to support significant radial loads (29,925 lbf dynamic rating) while maintaining dimensional stability under stress.
- Precision Tapered Bore: The 1:12 tapered bore ensures a secure, concentric fit on the shaft when used with appropriate adapter sleeves, minimizing slippage and vibration in high-torque applications.
- Optimized for Speed: The stainless steel cage and open design contribute to a high limiting speed of 4,300 rpm, suitable for various high-speed machinery applications.
- Durable Material Construction: Manufactured from chrome steel rings and balls with a stainless steel cage, this bearing offers excellent wear resistance and corrosion protection in challenging environments.
- Protruding Ball Design: With a ball protrusion of 1.486 mm, this design can accommodate slight misalignments and provides optimized contact geometry for smooth operation.
1319K Bearing Typical Application Areas
- Industrial Gearboxes and power transmission systems
