Frequently Asked Questions (FAQ)
-
What is the maximum vertical load this pot bearing can handle?
The standard model supports a vertical load of 3000 kN. Custom designs for higher loads are available upon request. -
Can the horizontal displacement be adjusted for different bridge designs?
Yes, the 100mm displacement is standard, but we can modify the bearing to accommodate larger or smaller displacements as per your project specifications. -
What is the typical lifespan of the PTFE sliding surface?
The PTFE surface is designed for long-term durability, often exceeding 20 years under normal operating conditions, with minimal wear. -
Is this bearing suitable for seismic zones?
Absolutely. The pot bearing’s ability to rotate and translate horizontally makes it ideal for accommodating seismic movements. We can provide additional seismic-resistant features if needed. -
What maintenance is required?
The bearing is almost maintenance-free due to its sealed design. Periodic visual inspections are recommended every 5 years, but no routine lubrication is necessary. -
Do you offer certificates or test reports?
Yes, we can provide material certificates, load test reports, and other documentation upon request. Please specify your requirements when ordering. -
What is the lead time for production?
Standard production takes about 30–45 days after order confirmation. Custom orders may require additional time. We work efficiently to meet your schedule. -
Can I get a sample for testing?
Samples are available for evaluation. Please contact our sales team to discuss sample availability and shipping costs.
