GBZY400×99 Circular Bridge Plate Rubber Bearing Factory Price Rubber Bearings Contact Me for Custom Orders

Circular plate rubber bearings (GYZ/GYZF4 series) are circular bridge bearings made by alternately laminating multiple layers of rubber and thin steel plates through vulcanization bonding, featuring the following characteristics:

• Uniform and reasonable force distribution
• Easy installation
• Economical and durable
• Strong adaptability

Main Technical Parameters

Product Classification

1. Standard Type (GYZ): Fixed bearings, suitable for bridge structures without displacement requirements
2. PTFE Slide Type (GYZF4): Sliding bearings with a surface composite polytetrafluoroethylene plate, GBZY400×99 Circular Bridge Plate Rubber Bearing Factory Price Rubber Bearings Contact Me for Custom Orders suitable for bridges requiring displacement compensation

Product Advantages and Features

• Circular structure provides more uniform force distribution
• Excellent seismic and vibration damping performance
• Strong weather resistance and long service life
• Low maintenance cost

Circular Plate Rubber Bearing Construction Guide

Construction Preparation Stage

1. Bearing Acceptance:

   • GBZY400×99 Circular Bridge Plate Rubber Bearing Factory Price Rubber Bearings Contact Me for Custom Orders Check factory certificate and test report
   • Appearance inspection: No cracks, delamination, or exposed steel plates
   • Dimension verification: Diameter and thickness tolerance ≤ ±2mm

2. Supporting Pad Stone Treatment:

   • Strength ≥ C40
   • Surface flatness ≤ 1mm/m
   • Elevation deviation ≤ ±2mm
   • Clean surface, free of oil and dust

Key Construction Technical Points

1. Positioning Control:

   • Use total station for precise layout
   • Center position deviation ≤ 3mm
   • Adjacent bearing surface height difference ≤ 1mm

2. Installation Process:

   • Standard bearings are directly installed on the leveling layer
   • PTFE slide type should first install stainless steel plate on the lower pad stone
   • Apply 5201 silicone grease lubricant evenly on the PTFE surface (thickness 2-3mm)

3. Level Control:

   • Measure with precision level
   • Level deviation ≤ 0.5‰
   • When using wedge-shaped steel plates for adjustment, no more than 3 layers

Special Condition Handling

1. Steep Slope Bridges:

   • Install wedge-shaped leveling steel plates
   • Bond steel plates and bearings with epoxy resin

2. Curved Bridges:

   • Pay attention to pre-eccentricity setting
   • Adjust bearing position according to design documents

3. Low-Temperature Construction:

   • Take insulation measures when ambient temperature is below 5℃
   • Prohibit installation during rain or snow
