How to Choose the Tungsten Carbide Grade for Bearings
Tungsten carbide bearings are typically manufactured using grades similar to ISO K-series, with a strong emphasis on wear resistance, hardness, and corrosion resistance. In bearing applications, components operate under continuous rotation, load, and friction, often in demanding environments such as high temperature, corrosive media, or insufficient lubrication conditions.
When selecting the appropriate carbide grade, key factors include load conditions, rotational speed, operating environment (e.g., presence of abrasive particles or corrosive fluids), and lubrication method. Grades with higher hardness offer excellent wear resistance and extended service life, while grades with higher cobalt or nickel binder content provide improved toughness and resistance to impact or edge chipping.
For high-load or high-speed bearing applications, achieving a proper balance between hardness, toughness, and corrosion resistance is critical to ensure stable operation and minimize wear.
Corresponding Chinese tungsten carbide grades. For example, K10 corresponds approximately to YG6 (high wear resistance), K20 to YG8 (general purpose), and K30–K40 to YG10–YG15 (higher toughness grades). Final grade selection depends on wear conditions, impact load, and service life requirements.
K10, K15, K20, K30, K40 Grade Equivalency Table (YG6, YG8, YG10, YG15)
| ISO Grade | General Characteristics | Common Chinese Grade Reference |
|---|---|---|
| K10 | High hardness, low cobalt content, excellent wear resistance | YG6 / YG6X |
| K15 | Slightly improved toughness while maintaining good wear resistance | YG6X / YG8X |
| K20 | General-purpose grade with balanced wear resistance and toughness | YG8 |
| K30 | Better toughness and impact resistance | YG10 / YG10X |
| K40 | High toughness and high cobalt content, suitable for higher impact conditions | YG13 / YG15 |
