Pot Bearing - Fixed, Guided and Free Sliding TypePot Bearing Allows Rotations by Shear Deformation. Pot bearing, also known as pot rubber bearing, with elastomeric bearing embedded inside of the steel plate, can be divided into fixed pot bearing, guided pot bearing and free sliding pot bearing. Pot bearings are special types of bridge bearings for taking large loads, large horizontal displacements and large rotation requirements in confined areas.Elastomeric Bearing Pad · Spherical Bearing · Seismic Isolation Bearing
The loading capacity of elastomeric bearings is limited, while pot bearings solved this problem, thus pot bearings are often regarded as suitable for use when bridges need large bearing reactions. PB-01: Pot bearing structure. PB-02: Pot bearing is made of high quality steel. Fixed pot bearing is unmoved in all directions.See all results for this questionWhat is a guided pot bearing?Guided pot bearing Guided pot bearingwith steel guide edge can be only moved in one direction. The stainless steel slide and PTFE slide further reduce the friction coefficient and guided pot bearing is used best when horizontal loads are relatively small (less than 20% of vertical Load). Guided pot bearing - some specificationsSee all results for this questionWhat is a free sliding pot bearing?Free sliding pot bearing can be movable in all directions. The added PTFE and stainless steel sliding surface between the piston and the sole plate creates a bearing assembly that allows horizontal movement in any direction. Bearing capacity of the pot bearing is 100% of the design capacity and allow overloading 10%.See all results for this question

Spherical bearing, also called spherical bridge bearing, is one type of bridge bearings with large rotation capacity. Similar with pot bearing, spherical bearing also can be divided into three types: fixed spherical bearing, guided spherical bearing and free sliding spherical bearing. With high strengthened steel body, spherical bearing is especially designed for high vertical, horizontal and lateral loads and where large Sliding bearing - Assaflex UKAssaflex UKSliding Bearings. in cases where there is significant horizontal displacement, in particular on the abutments, the number of laminations required for these deformations risks being incompatible with the buckling stability of the bearing or in the case of a very flexible support.Sliding Fixed Pot Bearing Bridge High Quality Best Price guide sliding pot for bridgeSliding Fixed Pot Bearing Bridge High Quality Best Price , Find Complete Details about Sliding Fixed Pot Bearing Bridge High Quality Best Price,Fixed Pot Bearing,Free Sliding Pot Bearings,Guide Sliding Bridge Bearing from Other Rubber Products Supplier or Manufacturer-VINH HUNG TRADING, CONSULTING AND CONSTRUCTION JOINT STOCK COMPANYPrice Range: $100 - $300

There are good reasons for this popularity, all stemming from the confined elastomer principle. A rubber pad, when tightly confined within a steel pot, will support an almost limitless stress. Tests to 57,000 psi show absolutely no change in the structure of the material.See more on cosmecinc guide sliding pot for bridgePot Bearings - Canam-BridgesThe pot is machined from a standard steel plate to the proper dimensions. Brass sealing rings prevent the elastomeric disc encased in the pot from extruding under pressure through the annular gap located between the piston and the inside of the pot plate. The piston, which fits in the pot, is in contact with the elastomeric disc (Figure 1).
Bridge Bearing Pads; Pot Bearings; This type of bearing may be considered the most important one from the commercial point of view, since the pot bearings represent the largest portion of the bearings market in the world. guide sliding pot for bridge In combination with flat sliding element and guides to form sliding guided bearings.

The POT contains an elastomeric layer of Neoprene. The Piston sits within the POT, on the elastomer and the vertical load applied on the Piston is transferred to the elastomer. PTFE is employed on the top of the piston to aid sliding movement. POT-PTFE Bearings can be employed for loads of MAURER Structural BearingsThe structural rotations are adjusted thanks to an elastomeric pad, which responds with high vertical stiffness and low rotation resistance, confined into a steel pot. The displacements are adjusted by a PTFE layer sliding on a stainless steel sheet.IRC 083-3: Standard Specifications and Code of Practice guide sliding pot for bridgeIRC 083-3: Standard Specifications and Code of Practice for Road Bridges, Section IX (Bearings), Part III (Pot, Pot-Cum-PTEE, Pin and Metallic Guide Bearings) Item Preview > remove-circle Share or Embed This Item.

The sliding element of expansion bearings shall be restrained against movement in the fixed direction by exterior guide bars capable of resisting the horizontal forces or 20 percent of the vertical design load on the bearing applied in any direction, whichever is greater. The sliding surfaces of the guide Guidance Note Bridge bearings No. 3 - Steel ConstructionThe friction on the sliding surface depends on the PTFE interface pressure and is typically 5%. If the sliding element is omitted, pot bearings provide horizontal restraint. Alternatively, the sliding element may be constrained by guides, creating a unidirectional guided bearing. Elastomeric bearings These may be of strip, rectangular pad or lami-G 9.1 - Steel Bridge Bearing Design and Detailing Steel Bridge Bearing Design and Detailing Guidelines Introduction The purpose of this guide is to present steel bridge bearing details that are cost effective, functional, and durable.

Home decoration is an art and reveals a lot about the choices and preferences of individuals.Can you use a sliding bearing on a bridge?It is specified by ASSHTO that sliding bearing cannot be used unless the bridge span is smaller than 15m. This is because sliding bearing cannot be purely used if the bridge experiences rotation movement. However, the span restriction for sliding bearing utilization can be disregarded when it is used in combination with other bearing types.See all results for this question
Articulation is the term for the configuration of bridge supports and choice of structural bearings that provides the necessary restraints to the superstructure whilst at the same time providing freedom to some displacements and rotations in order to avoid unnecessary forces on both the superstructure and substructure due to constraint..

Fixed pot bearings:Â The bearings only allows the head of structure to have rotary movement and transfer the pressure through a fixed point. Sliding pot bearings:Â This type of bearings includes Free sliding bearings and Guide sliding bearings, which allows the dead to have both rotary movements and unidirectional or multidirectional movements.BRIDGE BEARINGS - CCLIn the base plate a rocker is retained in the pot with a lubricated, dimpled PTFE disc to slide against the stainless steel plate. The stainless steel plate is fitted to the machined top plate between two guide rails, which resist the horizontal load in one direction. Horizontal movement occurs along the length of the guide rails. The deformation of the: Pot Bearings - Maurer SEThe structural rotations are adjusted thanks to an elastomeric pad, which responds with high vertical stiffness and low rotation resistance, confined into a steel pot. Displacements are adjusted by a PTFE layer sliding on a stainless steel sheet. For guided or fixed bearings, external lateral forces are transmitted by suitable restraints or guides.
