| Main Properties |
| High hardness |
HRC60-66. This allows chrome steel balls to withstand heavy loads and resist wear and deformation. |
|
| Dimentional Precision |
The material properties enable the chrome steel balls good finishing surface and dimentional precision. Based on high pricision, the noice of the bearings can be very low, even silent. |
|
| Low coefficient of friction |
Chrome steel balls have a low coefficient of friction, which means they can move smoothly and efficiently without generating excessive heat or wear. |
|
| Wear Resistance |
Chrome steel balls maintain their size and shape well over time, even under high loads or in extreme temperatures. This makes them a reliable choice for long-term use in industrial applications. |
