Metal-Polymer Composite Bearings

Self-lubricating bearings combining steel backing, sintered bronze, and PTFE-based polymer for exceptional dry-running performance and minimal maintenance.

WHAT IS IT

Multi-Layer Composite Technology

Metal-polymer composite bearings are engineered with a unique tri-layer structure that delivers exceptional performance in demanding applications. The composite design combines the mechanical strength of metal with the low-friction properties of advanced polymers.

Steel Backing

Low-carbon steel provides high load-carrying capacity, excellent heat dissipation, and structural rigidity for press-fit installation.

Porous Bronze Layer

Sintered bronze powder (0.20-0.35mm) maximizes thermal conductivity and serves as a reservoir for the polymer overlay.

PTFE-Based Polymer Overlay

Anti-friction layer enriched with PTFE, fibers, or solid lubricants provides self-lubrication and forms a protective transfer film on mating surfaces.

KEY ADVANTAGES

Why Choose Metal-Polymer Composite Bearings

Dry Running Capability

Self-lubricating design enables operation without external lubrication, ideal for applications where oil or grease is impractical.

Low Friction

PTFE-based overlay delivers friction coefficients as low as 0.03, reducing energy consumption and wear on mating surfaces.

Maintenance-Free

Eliminates the need for regular lubrication, reducing maintenance costs and equipment downtime significantly.

Wide Temperature Range

Operates reliably from cryogenic conditions (-195°C) to high temperatures (+280°C), suitable for extreme environments.

Chemical Resistance

Excellent resistance to chemicals, fuels, and hydraulic fluids. Low water absorption prevents swelling and dimensional changes.

Rotary & Oscillating Motion

Suitable for rotating, oscillating, and reciprocating movements. Transfer film protects mating surfaces during operation.

Compact Design

Thin-wall construction allows for very small radial design envelopes, ideal for space-constrained applications.

Low Noise Operation

Runs quietly without the stick-slip noise common in traditional bearings, perfect for automotive and office equipment.
