Types and Selection Guide

Pot Bearing Types

Type	Function
Fixed Bearing	Supports vertical load; restricts horizontal movement
Guided Sliding Bearing	Allows movement in one direction
Free-Sliding Bearing	Allows movement in two directions

Spherical Bearing Types

Type	Function
Fixed Bearing	Supports vertical load; restricts horizontal movement; accommodates larger rotation
Guided Sliding Bearing	Allows movement in one direction with larger rotation
Free-Sliding Bearing	Allows movement in two directions with larger rotation

Selection Guide

Fixed Bearing: Suitable for piers or girder ends where horizontal movement needs to be restricted

Guided Sliding Bearing: Suitable for girder ends where movement in one direction needs to be released
 

Free-Sliding Bearing: Suitable for wide decks, curved bridges, and areas requiring multi-directional movement
 

Spherical bearings are preferred for bridges with larger rotation requirements

Installation Guide
 

1.Verify bearing type and specifications against design drawings before installation
 

2.Clean the surface of pier or girder embedded steel plates; ensure level and free of debris
 

3.Place bearing according to design; adjust levelness and elevation
 

4.Secure fixed bearing to embedded plates; ensure sliding direction is correct for sliding types
 

5.Protect bearing from impact and contamination during concrete pouring

FAQ

1.What is the difference between pot bearings and spherical bearings?
Pot bearings feature a steel pot and elastomeric pad combination, offering high load capacity for conventional bridges. Spherical bearings utilize a spherical sliding surface, accommodating larger rotation angles for curved bridges, long-span bridges, and building isolation layers.
2.What is the lead time for pot bearings and spherical bearings?
Pot bearings and spherical bearings are custom products manufactured based on project drawings and technical requirements. Production is typically completed within 15 to 30 days after drawing confirmation. The exact lead time depends on order quantity, specifications, and raw material availability.
3.What other bridge and building component products does your company offer besides pot and spherical bearings?
As a comprehensive solution provider, our product line also includes: laminated rubber bearings, natural rubber bearings (LNR), high damping rubber bearings (HDRB), lead rubber bearings (LRB), rubber pads, bridge expansion joints, waterstops (PVC, rubber, steel-reinforced), sealants (polyurethane, polysulfide), and building isolation flexible pipes.
4.What is the quality assurance for the products?
We provide quality assurance for finished products. From raw material procurement and production process control to pre-shipment inspection, all steps are carried out in accordance with standards to ensure product performance meets technical specifications. 
5.What management system certifications does your company hold?
The company has established and operates an integrated management system, certified for quality management (ISO 9001), environmental management (ISO 14001), and occupational health and safety management (ISO 45001).
6.Can the parameters of pot bearings and spherical bearings be customized?
Yes. Parameters such as vertical load capacity, horizontal movement, rotation angle, and dimensions can be customized based on project drawings and technical requirements.
