JDB solid lubrication bearing

1. Flexible, simple, and convenient design with a wide range of applications: 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 operating conditions, significantly reducing maintenance needs and expenses related to lubricants and oil changes. 2. Can operate without external lubrication: Due to the higher coefficient of thermal expansion of the solid lubricant compared to the metal matrix, when the bearing begins to rotate, a thin oil film transfers onto the mating surface, enabling self‑lubrication. Consequently, solid self‑lubricating bearings are well suited for applications where conventional lubrication is difficult or impractical, even under low‑speed, high‑load conditions, delivering reliable performance. 3. Low operating costs: Traditional mechanical designs require frequent lubrication, regular oil level checks, and periodic inspections of the lubrication system to ensure proper flow. Such routine maintenance not only leads to environmental contamination but also increases overall upkeep expenses. In contrast, adopting self‑lubricating bearings helps maintain a clean working environment while substantially reducing the cost of lubricants. 4. Excellent performance under high load and low speed:
