Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 618 | Series designation for extra-light series, single row deep groove ball bearings. |
| 560 | Bore diameter in millimeters (560 mm). |
| M | Indicates a machined brass cage (based on the provided cage material being Stainless Steel, this is interpreted as a precision-machined solid cage). |
| A | Internal design variation, typically indicating specific internal geometry optimizations. |
618/560 MA Bearing Structural Features & Performance Benefits
- High Load Capacity: The single row deep groove construction is optimized to carry high radial loads, with a substantial static load rating for stable operation under heavy conditions.
- Precision and Accuracy: Manufactured to P6 tolerance class with a standard CN radial internal clearance, ensuring smooth, precise, and low-vibration running essential for high-accuracy applications.
- Robust Construction: Components made from Chrome Steel (rings and balls) and a Stainless Steel cage provide excellent durability, wear resistance, and corrosion resistance, contributing to a long service life.
- Open Design & Versatility: The open (unsealed) design allows for versatile lubrication options, making it suitable for systems with centralized lubrication. The specified temperature range of -30°C to 120°C ensures performance across various operational environments.
