Self-Lubricating Bearing Materials: The Ultimate Guide to Efficiency and Durability

How Do Self-Lubricating Bearings Work

How Do Self-Lubricating Bearings Work?

Self-lubricating bearings rely on a clever combination of materials and physics:

  • Embedded Lubricants: Solid lubricants are evenly distributed within the bearing material (e.g., metal, polymer, or composite).

  • Friction-Induced Release: During operation, friction generates heat, causing the embedded lubricants to migrate to the bearing’s surface.

  • Continuous Lubrication Layer: A thin, protective film forms between the bearing and its moving counterpart, reducing wear and preventing metal-to-metal contact.

Which Type of Bearing Metal is Self-Lubricated?

Several metals and composites excel in self-lubricating applications:

  • Bronze-Based Bearings:

      • Sintered bronze (oil-impregnated) is a classic choice.
      • Contains graphite or PTFE for dry lubrication.

  • Iron-Based Alloys:

      • Used in heavy-load applications with graphite additives.

  • Bimetal Bearings:

      • Steel-backed layers with a self-lubricating alloy surface.

  • Metal-Polymer Composites:

      • Example: Steel with PTFE coatings for low friction.

Product Introduction

The JDB solid embedded lubricant bearings are made from high-strength copper alloy as the base material. Based on the operational conditions, holes are machined into the working surface in specific proportions and filled with solid lubricant.

The high-strength copper alloy provides a high load-bearing capacity, while the solid lubricant can form a low-friction pair.

Under dry friction conditions, we design a pre-lubrication film on the bearing surface to ensure that the solid lubricant is transferred to the counterpart in the shortest possible time, forming an effective solid lubrication film.
