Frequently Asked Questions (FAQ)
-
Q: What is the maximum load capacity of this bridge rubber bearing?
A: The standard model is rated for 500 kN (approximately 50 tons). For higher loads, we can design custom bearings with additional layers or larger dimensions – please inquire. -
Q: Is this bearing compliant with ASTM D4014?
A: Yes, our manufacturing process strictly follows the ASTM D4014 standard for elastomeric bridge bearings. We perform routine testing to verify compliance. -
Q: Can I get bearings with custom dimensions?
A: Absolutely. We offer customizable length, width, thickness, and number of steel reinforcement layers. Provide your design requirements, and our engineers will propose a tailored solution. -
Q: How long does the bearing typically last?
A: Under normal bridge service conditions (moderate traffic, proper installation), the expected service life is 20–30 years. Factors such as extreme temperatures or chemical exposure can affect longevity. -
Q: Does the bearing require any maintenance?
A: Elastomeric bearings are virtually maintenance-free. No lubrication or adjustment is needed. However, periodic visual inspection for cracking or excessive deformation is recommended. -
Q: What is the lead time for an order?
A: For standard sizes, lead time is typically 10–15 working days. Custom orders may require 20–30 working days, depending on complexity. We ship from Port of Tianjin or Qingdao. -
Q: Do you provide installation guidance?
A: Yes, we provide detailed installation instructions and technical support. Our team can also assist with project-specific advice via email or video call. -
Q: What payment terms do you accept?
