Key Features & Technical Specifications
- Extreme Precision: Positioning accuracy ≤ 0.1°, enabling precise solar tracking to increase energy yield by up to 25% compared to fixed systems.
- Long Service Life: 25-year design life based on L10 bearing life calculation, using high-carbon chromium steel and special heat treatment.
- High Load Capacity: Supports axial, radial, and tilting moment loads simultaneously; load ratings are customizable for single/dual axis trackers.
- Advanced Sealing: Double lip seals protect against dust, moisture, and sand; IP65 rating available upon request for desert/coastal projects.
- Low Maintenance: Pre-lubricated with high-grade grease; optional central lubrication system facilitates easy maintenance.
- Corrosion Resistance: Surface treatment with black oxide or hot-dip galvanizing (optional) to withstand outdoor exposure for 25 years.
- Gear Integration: Internal or external gear teeth can be machined directly on the bearing ring, eliminating extra drive components.
- Compact Design: Optimized cross-section reduces weight and inertia, improving tracker dynamic response.

Frequently Asked Questions (FAQ)
-
Q: Can this bearing achieve 0.1° accuracy in all weather conditions?
A: Yes, the design incorporates temperature compensation and robust structure. Actual field accuracy depends on control system and tracker stiffness; our bearing ensures minimal backlash and consistent precision. -
Q: What is the warranty period?
A: We offer a standard warranty of 5 years against manufacturing defects. For extended warranty up to 25 years, please discuss with our sales team — terms vary by project. -
Q: How do you ensure the 25-year lifespan?
A: We use premium bearing steel, specialized heat treatment, and fatigue life simulation per ISO 281. Sealing and lubrication are optimized for solar tracker conditions. The 25-year design life is based on typical tracker operation profiles. -
Q: Can the gear teeth be customized for different drive systems?
A: Absolutely. We can machine spur or helical teeth with module from 4 to 20, and provide matching pinion recommendations. Both internal and external gear configurations are available. -
Q: Do you provide samples for testing?
A: Yes, we can supply sample bearings for your validation. Minimum order quantity may apply for custom dimensions. Lead time for samples is typically 4–6 weeks. -
Q: What kind of maintenance is required?
A: Our bearing is pre-greased for life under normal conditions. For extreme environments, we recommend re-greasing every 3–5 years. An optional central lubrication port simplifies this process. -
Q: How does your bearing compare to competitors?
A: Our focus on precision (0.1°), long life (25 years), and flexible customization allows us to meet stringent tracker requirements. We invite you to compare specifications; our engineering team can provide performance data for your specific application. -
Q: What are the payment terms and shipping methods?
A: Common terms include T/T, L/C. Shipment via sea or air from Chinese ports. For large orders, we can arrange door-to-door delivery. Contact us for a detailed quote.
