JDB solid lubrication bearing

1. Flexible, simple, and convenient design with broad application scope: In mechanical engineering, lubrication systems are often labor‑intensive and time‑consuming to implement. By using solid self‑lubricating bearings, there is no need to incorporate separate lubrication mechanisms, thereby eliminating the associated equipment costs. Moreover, these bearings can be tailored into various shapes to meet the specific requirements of diverse applications, significantly reducing maintenance needs and expenses related to lubricants and oil changes. 2. Can operate without external lubrication: Because the coefficient of linear thermal expansion of the solid lubricant exceeds that of the metal matrix, a thin oil film forms during startup and transfers onto the mating surface, enabling self‑lubrication. Consequently, solid self‑lubricating bearings are well suited for environments where lubrication is difficult or impractical, including locations where grease cannot be applied. Even under low‑speed, high‑load conditions, they provide effective lubrication. 3. Low operating costs: Conventional mechanical designs require frequent lubrication, regular oil level checks, and periodic inspections of the lubrication system to ensure proper flow. Such routine maintenance often leads to contamination of the machinery itself and its surroundings, driving up overall maintenance expenses. In contrast, adopting self‑lubricating bearings not only keeps the environment cleaner but also substantially reduces the cost of lubricants. 4. Excellent performance under high load and low speed conditions:
