619/530 MA Bearing Product Overview & Core Advantages
The 619/530 MA is a single row deep groove ball bearing designed for exceptional performance in demanding industrial applications. As a metric series bearing with a substantial 530 mm bore, it is engineered to handle primarily radial loads with high reliability. Its key advantages include a high precision P6 tolerance class for accurate rotational performance, a robust construction using chrome steel rings and balls for durability, and a stainless steel cage for enhanced corrosion resistance and operational stability. This bearing is an ideal solution for applications requiring a combination of high load capacity and precision in a large bore size.

| Code Segment | Technical Meaning |
|---|---|
| 619 | Series designation for deep groove ball bearings. |
| 530 | Bore diameter in millimeters (530 mm). |
| M | Indicates a machined brass cage (based on industry-standard suffix interpretation for this series). |
| A | Not explicitly defined in standard tables for this context, but often denotes internal design optimizations. |
619/530 MA Bearing Structural Features & Performance Benefits
- High Load Capacity: Engineered with a deep groove raceway, this bearing is optimized to support significant radial dynamic load ratings of 109,707 lbf and radial static load ratings of 209,072 lbf, making it suitable for heavy-duty machinery.
- Precision Performance: Manufactured to a P6 tolerance class, it ensures minimal running noise and vibration, contributing to smoother operation and extended service life in precision applications.
- Robust Cage Design: The inclusion of a machined brass cage (MA suffix) provides superior strength and guidance for the balls, enhancing operational stability at the limiting speed and in challenging conditions.
- Standard Internal Clearance: Features a CN radial internal clearance, which is the standard group, offering a versatile fit for a wide range of common operating conditions.
- Wide Temperature Range: Constructed from high-grade chrome steel, it operates effectively within a temperature range of -30°C to 120°C.
