Wound Plastic Bearings Overview

Wound plastic bearings are high-performance plain bearings composed of filament-wound composite materials. Typically constructed from thermoset resin matrices reinforced with fiberglass or other high-strength fibers, these bearings are designed for lightweight, corrosion-resistant, and maintenance-free operation. Their advanced structure delivers excellent load-carrying capabilities and low friction under dry or marginally lubricated conditions, making them ideal for harsh environments and demanding mechanical systems.

Lightweight and high strength for weight-sensitive applications
Corrosion and chemical resistance, ideal for wet or harsh environments
Self-lubricating, low friction, and maintenance-free
Excellent wear resistance and dimensional stability
Customizable material blends, sizes, and special features

Common Applications:

Agricultural and construction equipment: pivots, loader arms, joints
Marine and offshore: rudder shafts, winches, underwater components
Hydraulic and pneumatic cylinders: guide and support bushings
Renewable energy: wind turbines, solar tracking systems
Transportation and rail: bogie systems, couplings, suspension

Customization: We offer custom composite blends, dimensions, PTFE linings, lubricant grooves, and metal-backed hybrids to meet your specific needs.

A wound plastic bearing is a non-metallic plain bearing made from filament-wound composite materials, offering high strength, low friction, and corrosion resistance.

Yes, most wound plastic bearings are designed for dry operation and provide self-lubricating performance under normal loads and speeds.

Absolutely. Their composite structure resists water, salt, and chemicals, making them ideal for submerged and corrosive applications.

Depending on the formulation and design, wound plastic bearings can handle high radial and axial loads, especially in oscillating or static load scenarios.

Yes. We offer complete customization in material selection, dimensions, and design features to match your specific technical requirements.
