61826 Bearing Product Overview & Core Advantages
The 61826 metric ball bearing is a high-precision, single row deep groove ball bearing designed for demanding applications. Engineered to primarily accommodate radial loads, it offers a compact design with a relatively large bore diameter of 130mm and a narrow width of 18mm. Manufactured to a P6 tolerance class, it ensures high running accuracy and is ideal for high-speed operation up to 4,800 rpm. Its open design and high-grade components make it a reliable choice for high-performance machinery requiring precision and reliability.
61826 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Interpretation | Technical Significance |
|---|---|---|
| 61826 | Basic Model Number | Denotes a standard single row deep groove ball bearing with a 130mm bore and 165mm OD. |
| Open (No Seal Suffix) | Seal Type | No contact seals, enabling higher limiting speeds and allowing for custom lubrication systems. |
| P6 | Tolerance Class | Indicates tighter dimensional and running accuracy tolerances than standard (P0) bearings. |
| CN | Radial Internal Clearance | Specifies the standard (normal) radial internal clearance group for general applications. |
61826 Bearing Structural Features & Performance Benefits
High-Speed Capability: The open design and stainless steel cage minimize friction and allow for efficient lubrication management, contributing directly to the high limiting speed of 4,800 rpm. This makes the 61826 an excellent choice for high-speed applications.
High Load Capacity & Precision: Constructed from chrome steel for both rings and balls, this bearing offers a high radial dynamic load rating of 8,475 lbf and a radial static load rating of 9,667 lbf. The P6 tolerance class ensures precise shaft guidance and low running noise and vibration.
Robust Construction: The single row deep groove construction provides a robust and versatile solution. The stainless steel cage provides high strength and corrosion resistance, enhancing the bearing's operational reliability.
61826 Bearing Typical Application Areas
The 61826 bearing is suited for a wide range of industrial machinery requiring precision and high-speed performance. Common applications include:
- Electric Motors and Generators
- Machine Tool Spindles and other precision machinery
- Pumps and Compressors
- Material Handling Equipment
- Gearboxes and transmission systems
