Thin-walled Bearings With Four Contact Points And Constant Section Seal

Structural Characteristics
Thin-walled Lightweight Design
Significantly reduced inner/outer ring thickness minimizes weight and saves installation space, suitable for compact systems.
High-strength alloy or ceramic materials ensure rigidity and fatigue resistance despite the thin walls.
Four Contact Points Design
Rolling elements form four contact points with raceways (e.g., four-point contact ball bearings), enabling simultaneous radial, bidirectional axial loads, and moment resistance.
Uniform contact distribution improves load efficiency and reduces localized stress.
Constant Section Seal Structure
Uniform circumferential cross-section combined with integrated seals (e.g., lip seals or labyrinth seals) prevents dust and liquid ingress, extending service life.
Seals are integrated into the bearing, eliminating the need for additional space.
Working Principle

• Loads are transmitted through four contact points, adapting to complex combined forces.
• Seals dynamically isolate contaminants during rotation, maintaining stable lubrication.
