61868 MA Bearing Product Overview & Core Advantages
The 61868 MA is a single row deep groove ball bearing designed for high-precision applications demanding exceptional radial load capacity and operational stability. Engineered with a P6 tolerance class and manufactured from high-grade chrome steel, this bearing is positioned for scenarios requiring superior running accuracy and dimensional consistency. Its open design facilitates direct lubrication and allows for high limiting speeds, making it an ideal component for robust industrial systems.
61868 MA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| MA | Indicates a brass cage, guided by the rolling elements. This cage type offers high strength and is suitable for high-speed operation and demanding applications. |
Core Designation: The base model 61868 defines it as a single row deep groove ball bearing with a 340 mm bore diameter, 420 mm outside diameter, and 38 mm width.
61868 MA Bearing Structural Features & Performance Benefits
- High Radial Load Capacity: The optimized deep groove raceway and robust construction enable it to handle significant radial dynamic load ratings of 40016 lbf and static load ratings of 61822 lbf, ensuring reliable performance under heavy loads.
- Precision & Stability: Manufactured to a P6 tolerance class with strict dimensional controls (e.g., bore diameter tolerance: -0.03mm to 0), this bearing provides excellent running accuracy, reduced vibration, and consistent performance in precision assemblies.
- High-Speed Capability: The combination of the brass cage (MA) and an open design contributes to a high limiting speed of 2,400 rpm, making it suitable for applications requiring rapid rotation.
- Versatile Operating Range: Constructed from chrome steel components, the bearing operates effectively within a temperature range of -30°C to 120°C, accommodating various industrial environments.
- Customizable Lubrication: The open seal type allows for the application of specific lubricants tailored to the operational needs, optimizing performance for the application's speed and temperature conditions.
