61830 MA/W64 Bearing Product Overview & Core Advantages
The 61830 MA/W64 is a single row deep groove ball bearing engineered for superior performance in demanding applications. This metric bearing is characterized by its ability to accommodate high radial loads and moderate axial loads in both directions. Its open design and Solid Oil lubrication system ensure reliable operation, making it an ideal choice for applications requiring robust performance and long service life. The bearing is manufactured to ABEC 1 | ISO P0 tolerance standards, providing consistent quality and precision.
61830 MA/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 61830 | Basic Bearing Series & Size Designation | Indicates a single row deep groove ball bearing with a 150mm bore, 190mm OD, and 20mm width. |
| MA | Machined Brass Cage | Denotes a high-strength, machined metal cage for excellent guidance and stability at high speeds. |
| W64 | Solid Oil Lubrication | Specifies the bearing is pre-lubricated with a Solid Oil polymer matrix, offering a maintenance-free, long-life solution that is resistant to wash-out and contamination. |
61830 MA/W64 Bearing Structural Features & Performance Benefits
- High Load Capacity: The optimized raceway geometry and high-quality chrome steel construction enable it to support significant radial dynamic load ratings of 10,971 lbf and radial static load ratings of 13,713 lbf.
- High-Speed Capability: The combination of the machined brass cage (MA) and Solid Oil lubrication allows for a high limiting speed of 4,300 rpm, ensuring stable performance in fast-rotating machinery.
- Maintenance-Free Operation: The integrated Solid Oil (W64) system eliminates the need for re-lubrication, reduces friction, and provides protection against contamination, significantly extending the bearing's service interval.
- Precision & Reliability: Manufactured to ABEC 1 | ISO P0 standards with a standard CN radial internal clearance, this bearing delivers consistent running accuracy and smooth operation.
