6216 MA/C3B20 Bearing Product Overview & Core Advantages
The 6216 MA/C3B20 is a single row deep groove ball bearing designed for robust performance in a wide range of industrial applications. Engineered for primarily radial loads, this bearing features a machined brass cage (MA) and a C3 radial internal clearance, making it suitable for applications with thermal expansion or where interference fits are used. Its open design allows for versatile lubrication options, while the high-quality chrome steel construction ensures durability and reliable operation. This bearing is an excellent choice for general machinery requiring a balance of performance, cost-effectiveness, and high load capacity.
Model Code Breakdown
| Code Segment | Interpretation | Technical Significance |
|---|---|---|
| 6216 | Basic Bearing Series & Size | Denotes a standard 6000 series deep groove ball bearing with an 80mm bore, 140mm OD, and 26mm width. |
| MA | Machined Brass Cage | Indicates a machined brass cage, offering high strength, excellent guidance, and suitability for high-speed applications and demanding conditions. |
| C3 | Radial Internal Clearance | Specifies a greater than normal radial internal clearance, ideal for applications with shaft or housing interference fits, or where operational temperatures cause thermal expansion. |
| B20 | Bearing Coating | Signifies a specific surface treatment or coating, often for enhanced corrosion resistance. |
6216 MA/C3B20 Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & High Load Capacity: The optimized deep groove geometry enables the bearing to handle significant radial dynamic load rating of 16,366 lbf and a radial static load rating of 12,364 lbf, making it a robust solution for heavy-duty applications.
- Machined Brass Cage (MA): This cage material provides superior strength and stability compared to stamped cages, contributing to smoother operation, reduced friction, and enhanced performance at the limiting speed of 8,500 rpm.
- Optimized Internal Clearance (C3): The C3 clearance provides operational flexibility, accommodating thermal expansion and press fits without compromising bearing performance or service life.
- Open Seal Type & Lubrication Versatility: The open design allows for easy initial lubrication and re-lubrication, enabling users to select the optimal grease or oil for specific operating conditions within the temperature range of -30°C to 120°C.
- Standard Precision & Material Quality: Manufactured to ABEC 1 | ISO P0 tolerance class with chrome steel rings and balls, ensuring consistent quality, reliable operation, and long service life in general industrial machinery.
