DLR Directly Lubricates Bearings

DLR Directly Lubricates Bearings enhance wear resistance and service life under high-speed, heavy-load conditions by reducing lubrication path loss and optimizing oil film distribution. Common designs include:
Integrated Oil Channel Structure: Micro-oil channels in inner/outer rings deliver lubricant directly to contact areas.
Oil-Air Hybrid Lubrication: Combines compressed air with oil mist for efficient cooling and lubrication.
Self-Lubricating Material Coating: Solid lubricant (e.g., molybdenum disulfide) applied to raceways for low-lubrication or maintenance-free operation.
