About Hybrid deep groove ball bearing
| Category | Hybrid deep groove ball bearing |
| Overview | Hybrid bearings have rings made of bearing steel and rolling elements made of bearing grade silicon nitride (Si3N4), which make the bearings electrically insulating. |
|
Features and Benefits |
1. Protection from electric current damage 2. Higher speed capability 3. Long service life 4. High wear-resistance 5. High bearing stiffness 6. reduced risk of contamination and degradation 7. Less sensitivity to temperature gradients |
| Application | Electric motors, power tools and high-speed drives. |
