Frequently Asked Questions
-
What is the typical lifespan of your rubber bearing?
With proper installation and normal conditions, our bearings can last 20-30 years, depending on environmental factors and load cycles. -
Can you supply bearings for curved bridges?
Yes, we can design bearings with a spherical or curved surface to accommodate rotational movements of curved or skewed bridges. -
Are your bearings suitable for cold regions like Siberia or Canada?
Absolutely. Our rubber compound is formulated to maintain flexibility at -40°C, making it ideal for cold climates. -
Do you offer installation guidance?
We provide detailed installation drawings and technical support. On-site commissioning assistance is available upon request. -
What is the minimum order quantity?
MOQ is typically 50 pieces for standard sizes, but we can negotiate for smaller quantities depending on the project. -
How are the bearings packaged for export?
Each bearing is individually wrapped in plastic, then packed in wooden crates with steel strapping to prevent damage during shipping. -
Can you provide certificates of material compliance?
Yes, we can issue test reports and material certificates as per your requirements. Third-party inspection is also welcome. -
What is the lead time for a typical order?
Standard lead time is 15-25 working days after confirmation of all specifications. Custom orders may take longer.
