  • High-strength copper alloys serve as the base material, with their surfaces proportionally tailored according to usage conditions. These surfaces are filled with solid lubricating columns, enabling the formation of a high load-bearing, solid lubricant-infused structure.

Metal-Polymer Bearings

  • Ideal for low-speed, heavy-load applications such as continuous rotation and swing where oil lubrication is impractical or prohibited. This simplifies the lubrication system design, reducing maintenance costs and time. It offers excellent wear resistance, low friction coefficients, and a long service life.

Oilless Bearings with Embedded Solid Lubricants

Oilless bearings for high-temperature environments

Our maintenance-free oilless bearings, embedded with solid lubricants, are ideal for conditions where traditional ball bearings fall short, such as under high loads (static or fluctuating pressures) or impact loads. These bearings are also preferred in environments that can accelerate wear, including:

  1. High temperatures
  2. Dusty areas
  3. Under sea water
  4. Within chemical solutions
  5. At low sliding speeds
  6. In spaces where compact design is essential

Solid Lubrication System

Graphite Crystal Structure

The primary solid lubricant used in our bearings is graphite. This material is chemically stable and boasts exceptional thermal stability, making it suitable for use in temperatures ranging from 200° to 400° Celsius without the need for additional cooling.

During operation, graphite is released from embedded pockets within the bearing and transferred to the counterpart material. This transfer creates a lubricated surface characterized by low shear strength, enhancing the sliding process.

In certain instances, our oilless bearings can also be infused with oil-soaked graphite—available upon request—to further enhance sliding properties, including reduced friction, wear, and improved anti-seizure characteristics.

Types of Oilless Bearings with Embedded Solid Lubricants (Graphite)

There are two primary types of oilless bearings that utilize embedded solid lubricants:

High-Strength Brass Bearings: Known for their excellent initial run-in properties, these bearings facilitate smoother starts and operations.

Aluminum Bronze Bearings: These bearings are recognized for their exceptional robustness and durability, especially under strenuous conditions.

Both types are composed of base metals interspersed with hard particles, which contribute to their superior wear resistance and robustness at high temperatures. They are particularly suited for special environments where standard bearings would fail. The combination of graphite (as a solid lubricant) and high-performance base materials results in bearings with high adaptability and enhanced performance.
