61872 MA/W64 Bearing Product Overview & Core Advantages
The 61872 MA/W64 is a single row deep groove ball bearing designed for demanding industrial applications requiring high reliability and consistent performance under radial loads. Its metric dimensions and open design facilitate efficient heat dissipation and are complemented by Solid Oil lubrication, providing a maintenance-free solution with a wide operating temperature range. This bearing is engineered for applications where standard tolerances (ABEC 1 / ISO P0) and a standard radial internal clearance (CN) are sufficient, offering a robust and cost-effective precision bearing solution.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 61872 | Basic bearing series number, indicating a single row deep groove ball bearing with a specific dimension series. |
| MA | Designates a machined brass cage (cage material). This cage offers high strength and stability, suitable for high-speed applications and demanding operating conditions. |
| W64 | Indicates the bearing is lubricated with Solid Oil. This is a polymer matrix saturated with oil, providing long-term lubrication, resistance to wash-out, and a maintenance-free operation. |
61872 MA/W64 Bearing Structural Features & Performance Benefits
- High Load Capacity: Manufactured from chrome steel for both rings and balls, this bearing delivers a high radial dynamic load rating of 40,915 lbf and a radial static load rating of 64,071 lbf, ensuring durability and long service life under significant radial stresses.
- Optimized for Stability: The incorporation of a machined metal cage (MA) ensures precise guidance of the rolling elements, contributing to smooth operation, reduced friction, and enhanced suitability for applications with moderate limiting speeds.
- Maintenance-Free Operation: The Solid Oil (W64) lubrication system is sealed within the bearing, eliminating the need for re-lubrication. It performs reliably across a broad temperature range from -30°C to 120°C and is resistant to contamination.
- Precision & Consistency: Built to ABEC 1 / ISO P0 tolerance class and standard CN radial internal clearance, this bearing provides reliable and predictable performance for a wide array of general industrial applications.
61872 MA/W64 Bearing Typical Application Areas
This versatile bearing is ideally suited for:
- Industrial Gearboxes and Power Transmission Systems
- Electric Motors of medium to large frame sizes
- Material Handling Equipment such as conveyor pulleys
- Agricultural Machinery
