Rolling elements are precision-engineered components in industrial bearings that facilitate smooth rotational motion by reducing friction between moving parts.
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Hardness | 60-62 HRC | |
| Sphericity | ≤0.001 mm | |
| Lubrication | High-temperature grease or oil mist | |
| Load Capacity | Dynamic: 150 kN, Static: 300 kN | |
| Surface Roughness | Ra ≤0.05 μm | |
| Temperature Range | -40°C to +250°C (steel), up to 800°C (ceramic) | |
| Diameter Tolerance | ±0.0025 mm |

Manufacturer profiles associated with Rolling Elements.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
High-carbon chromium steel (AISI 52100) is standard for most applications due to its hardness and fatigue resistance. For extreme temperatures above 250°C, silicon nitride ceramic balls provide superior thermal stability and corrosion resistance.
Precision manufacturing ensures consistent size and sphericity, while material selection accounts for thermal expansion coefficients. Lubrication systems and bearing clearance designs accommodate expansion without compromising performance.
Regular lubrication replenishment, contamination monitoring, and periodic inspection for surface pitting or spalling. Replacement intervals depend on operating cycles and environmental conditions.
