Key Features & Advantages

High Load Capacity

Designed to withstand heavy static and dynamic loads from PV modules, wind, and snow, ensuring stable operation of large-scale solar trackers.

Maintenance-Free, Self-Lubricating Design

Made with advanced self-lubricating materials, eliminating the need for regular greasing and significantly reducing operation and maintenance costs.

Excellent Environmental Resistance

Resistant to UV radiation, corrosion, high temperatures, dust, and humidity, suitable for deserts, coastal areas, and other harsh outdoor environments.

Lightweight and High-Strength Structure

Aluminum alloy housing reduces system weight while maintaining high mechanical strength, improving tracker responsiveness and overall system efficiency.

Optimized Curved Contact Surface

The specially designed curved bearing surface prevents displacement caused by vibration or axial forces and compensates for minor installation tolerances, ensuring smooth and stable rotation.

Product Range

GF Bearing is available in multiple sizes and configurations to meet different tracker system requirements, with options including aluminum housing, galvanized steel, and Zn-Al-Mg coated structures. Customization is available upon request.

GF Bearing is not just a mechanical component — it is a key enabler of efficient, durable, and high-performance solar tracking systems.

Feature

GF Bearing Assembly

Plain Bearing Assembly

Swing Angle

±10° self-aligning movement

0°, no angular compensation

Installation

Easy and fast; no need for high-precision alignment

Slower; high installation accuracy required

Inner Bearing Retention

Ball core securely fixed, not easy to fall out

Ball may fall out under long-term radial stress

Tolerance to Structural Deformation

Can accommodate slight tracker deformation or misalignment

Sensitive to misalignment; performance degrades with structure shift

Maintenance

Low friction, low noise, maintenance-free

May require periodic inspection or lubrication depending on material
