6320 MA/C3B20 Bearing Product Overview & Core Advantages
The 6320 MA/C3B20 is a single row deep groove ball bearing engineered for exceptional performance in demanding industrial applications. This metric bearing is characterized by its high radial load capacity and robust construction. Its open design allows for versatile lubrication options, while the C3 radial internal clearance makes it ideally suited for applications involving thermal expansion or where interference fits are used. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides reliable and precise operation, offering an excellent balance of performance, durability, and value for a wide range of machinery.
6320 MA/C3B20 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6320 | Basic Bearing Number | Specifies the standard dimensions: 100 mm bore, 215 mm OD, 47 mm width. |
| MA | Machined Brass Cage | Indicates a high-strength, machined metal cage suitable for high-speed operation and demanding conditions. |
| C3 | Radial Internal Clearance | Denotes a greater than normal internal clearance, ideal for applications with shaft misalignment, thermal expansion, or heavy interference fits. |
| B20 | Optimized Internal Design | Signifies an optimized internal geometry that enhances load rating and overall performance. |
6320 MA/C3B20 Bearing Structural Features & Performance Benefits
- High Load Capacity: The deep groove raceway and optimized internal design (B20) enable the bearing to support high radial dynamic load ratings of 39,117 lbf and static load ratings of 31,473 lbf.
- Robust Construction: Manufactured from chrome steel for both rings and balls, ensuring high hardness, wear resistance, and a long operational lifespan.
- High-Speed Capability: The machined brass cage (MA) provides excellent dimensional stability and strength, contributing to stable operation at the limiting speed of 6,000 rpm.
- Operational Versatility: The open seal type allows for the application of various lubricants to suit specific operational needs, while the C3 clearance accommodates thermal expansion and heavy press fits, preventing premature failure.
- Wide Temperature Range: Suitable for operating temperatures from -30°C to 120°C, making it adaptable to diverse industrial environments.
