Frequently Asked Questions (FAQ)
-
What is the maximum load capacity of this bearing?
The load capacity depends on the specific design and installation conditions. For a 400mm OD x 200mm height bearing, typical vertical load capacity ranges from 500 kN to 1500 kN, but we strongly recommend consulting our engineering team for project-specific calculations. -
Can the hardness be customized?
Yes, the Shore A hardness can be adjusted from 50 to 80 based on your requirements. Please specify when placing an order. -
How long does the rubber bearing last?
With proper installation and normal environmental conditions, our bearings are designed to last 30–50 years. The actual service life may vary depending on factors like temperature, UV exposure, and traffic intensity. -
Are the anchor bolts included in the price?
Yes, standard anchor bolts made of high-strength zinc-plated steel are included with each bearing. Different bolt lengths or materials are available upon request. -
Do you provide installation guidelines?
We supply a detailed installation manual with each shipment. Additionally, our technical team can provide remote support or on-site guidance if needed. -
Can this bearing be used in seismic zones?
Yes, the elastomeric design offers good energy dissipation and is suitable for moderate seismic applications. For high-seismic areas, we recommend our seismic isolation bearings (available upon request). -
What is the minimum order quantity (MOQ)?
Our standard MOQ is 10 pieces. For smaller quantities, please contact us to discuss availability. -
How do you ensure quality control?
Each bearing undergoes dimensional inspection, hardness testing, and visual check before packing. We also perform random sample testing for compression and shear properties to ensure consistent quality.
