1217 Bearing Product Overview & Core Advantages
The 1217 double row angular contact ball bearing is engineered for applications requiring high radial load capacity and robust performance. This precision bearing features an open design, facilitating direct lubrication for optimal performance in demanding environments. Its double row construction provides superior rigidity and stability, making it ideal for supporting substantial combined loads. Manufactured from high-grade chrome steel for both rings and balls, with a durable stainless steel cage, it ensures reliable operation and long service life. The bearing is pre-lubricated and operates effectively within a temperature range of -30°C to 110°C.
1217 Bearing Model Code Explained, Specifications & Naming Convention
The model number 1217 follows a standard metric designation. A breakdown of its core components is provided below:
| Code Segment | Technical Interpretation |
|---|---|
| 12 | Indicates the bearing series, defining the cross-sectional dimensions and load capacity profile. |
| 17 | Represents the bore diameter in millimeters. Calculated as 17 x 5 = 85 mm. |
| (Open) | The absence of a seal suffix denotes an open bearing design, allowing for custom lubrication regimes and high-speed capability. |
1217 Bearing Structural Features & Performance Benefits
The design of the 1217 bearing translates directly into significant performance advantages:
- High Rigidity & Stability: The double row ball bearing configuration provides a much stiffer support structure compared to single row designs, effectively minimizing shaft deflection under heavy radial loads.
- Superior Load Capacity: With a dynamic load rating of 10980 lbf and a static load rating of 4680 lbf, this bearing is built to handle significant combined loads in industrial machinery.
- Optimized for Speed: The standard bearing dimensions (85mm bore, 150mm OD, 28mm width), combined with the low-friction stainless steel cage, contribute to a high limiting speed of 5,600 rpm.
- Durable Construction: The use of chrome steel for rings and balls ensures high wear resistance and durability, while the stainless steel cage offers excellent corrosion resistance and strength.
1217 Bearing Typical Application Areas
The 1217 double row angular contact ball bearing is suited for a wide range of industrial applications where high radial load capacity and rigidity are paramount. Common uses include:
- Industrial Gearboxes and Transmissions
- Material Handling Conveyor Systems
- Medium-duty Electric Motors
- Agricultural Machinery
- General Industrial Machinery requiring robust bearing solutions
