61819 Bearing Product Overview & Core Advantages
The 61819 metric ball bearing is a single row deep groove ball bearing engineered for high-precision radial load applications. Characterized by its open design and superior dimensional accuracy with a P6 tolerance class, this bearing delivers reliable performance in demanding environments. Its compact cross-section, with a 95 mm bore and 13 mm width, makes it an ideal solution for space-constrained assemblies requiring high rotational accuracy and smooth operation.
61819 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 61 | Bearing series, indicating a deep groove design with a thin cross-section. |
| 819 | Size code specifying a 95 mm bore diameter, 120 mm outside diameter, and 13 mm width. |
| Open | No seals or shields, allowing for higher limiting speeds and optimal heat dissipation. |
| P6 | Tolerance class denoting higher dimensional and running accuracy than standard bearings. |
| CN | Standard radial internal clearance for normal operating conditions. |
61819 Bearing Structural Features & Performance Benefits
Constructed from high-grade chrome steel rings and balls with a stainless steel cage, the 61819 is built for durability and corrosion resistance. The single row deep groove geometry is optimized for high-speed operation, supporting a limiting speed of 6,700 rpm. Its open seal type minimizes friction and allows for custom lubrication regimes, making it suitable for applications where specific greases or oils are required. The P6 tolerance ensures precise shaft alignment and reduced vibration, contributing to smoother running and extended service life. With a radial dynamic load rating of 4,474 lbf and a static load rating of 3,957 lbf, it offers robust performance for substantial radial loads.
61819 Bearing Typical Application Areas
- Precision spindles in machine tools and grinding applications
- Electric motors and generators requiring high-speed operation
- Industrial gearboxes and power transmission systems
- Medical equipment and laboratory instruments
- Agricultural machinery and material handling equipment
