Pot Bridge Bearing,Pot Type Bearing
The pot rubber bearing is the use of semi closed elastic rubber blocks of steel in the pelvic cavity, the characteristics of the three stress state of fluid, to achieve the rotation of the upper bridge, at the same time by the intermediate steel plate of polytetrafluoroethylene (F4) low friction coefficient between stainless steel plate and the top plate to achieve the level of the displacement of the upper structure, from the test data, the rubber in three dimensional compressive elastic modulus constraint state is 50000kg/cm2, increased nearly 20 times than the compressive elastic modulus without lateral restraint, thus bearing capacity is greatly improved, to solve the plate rubber bearing capacity limitations, can satisfy the bearing force, horizontal displacement large and large angle requirements.
The basin type support mainly has GPZ series, GPZ (II) series, GPZ (III) series, GPZ (KZ) seismic series, GPZ (2009) series and other specifications series
GPZ series of pot rubber bearing has low building height, sliding surface, small friction coefficient, large bearing capacity, flexible rotation performance, good cushioning performance, simple structure, light weight, low price, is the best support construction of continuous girder bridges.
pot rubber bridge bearing have been designed to be very easy to install, maintenance-free and cost-effective.Bridge Pot Bearings are designed for very high vertical, horizontal and lateral loads and where rotational structural displacements need to be accommodated.

Pot type rubber bridge bearing can be used in steel or concrete structures. These
low profiles, compact bearings are particularly useful to transmit large vertical load
while accommodating large movements and multi-directional rotation.Separate
mechanisms for rotation and translation (where applicable) provide minimum
eccentricity of the load and minimum frictional resistance to movement. High side
loads can also be accommodated simultaneously.
Different types of Elastomeric bridge pot bearing:
(a) Twoway moveable bearing has vertical rotation,longitudinal and horizontal gliding
performances and its serial number is SX;
(b) One-way movable bearing has vertical rotation and one-way gliding performances and its serial number is DX;
(c) Fixed bearing: only has vertical rotation performance and its serial number is GD.
plastic bags with pallets, protective material on top and bottom of bearings.
a. The vertical rotation angle of the bearing is not less than 40
b. The vertical bearing capacity (KN) of 1000 to 50000 is divided into 28 levels, the
bearing capacity of non slip surface is uneven vertical 10.
c. Friction coefficient: normal temperature type μ≤0.04 ,hardy type μ≤0.06.
