What Is a Fiber Bushing?
Modern industrial equipment increasingly requires bearing components that can withstand heavy loads, vibration, water exposure, and continuous operation. Traditional bronze and metal bushings often suffer from wear, corrosion, lubrication dependency, and costly maintenance.
A fiber bushing is a high-strength composite bearing manufactured using fiber-reinforced materials and advanced filament winding technology. Designed to operate under demanding conditions, fiber bushings provide a lightweight, corrosion-resistant, and self-lubricating alternative to conventional bearing materials.
Structure & Performance Features
The performance of a fiber bushing depends largely on its internal structure and material composition. Techemer combines reinforced fiber technology with self-lubricating materials to provide outstanding wear resistance, impact strength, and operational reliability.
Fiber composite bearings feature a three-layer design:
Self-Lubricating Sliding Layer
PTFE fiber with graphite filler for self-lubrication and wear resistance.
Load-Bearing Layer
Glass fiber winding with epoxy resin for strength and impact resistance.
Reinforced Backing Layer
Multi-angle winding structure for rigidity and dimensional stability.
Technical Parameters
As a professional fiber bushing manufacturer, Techemer designs fiber bushings to deliver reliable performance in high-load, low-speed, water-lubricated, and maintenance-free applications. The technical data below highlights the core properties of our composite fiber bushings, including wear resistance, load capacity, lubrication performance, and environmental adaptability.
