Application

SBX:

SBX Structural Expansion Bearings are used when construction tolerances, high load and rotation are prominent with beam spans being excessive. This bearing is the most resilient in our full line of expansion bearings. Typical applications:

  • Bridges.
  • Complex Structures: include structures where vortex shedding and seismic conditions are prevalent.


STX:

STX Expansion Bearings are used when construction tolerances, loads and rotation are moderate. This bearing has an extremely low coefficient of friction, which is exceptional for use where expansion is large. Please note: Fabreeka® can supply various types of Teflon, based on customer requirements. Typical applications:

  • Pedestrian Bridges.
  • Vessels.
  • Parking garages.
  • Pipelines.
  • Small buildings.
  • Slip joints.
  • Tanks.
  • Expansion joints.


TTX:

TTX Expansion Bearings are used when construction tolerances, loads and rotation are moderate. This bearing has a higher coefficient of friction than the STX Bearing and is used where expansion criterion is limited. Typical applications:

  • Tanks.
  • Vessels.
  • Slip Joints.
  • Expansion Joints.


GGX:

GGX Expansion Bearings are used when temperature is a factor - in excess of 275°F. Graphite is a versatile engineered material with an unusual combination of physical, electrical and chemical properties. These bearings are ideal for hostile environments where other types of materials may break down due to acids, solvents and high temperature. The GGX Expansion Bearings achieve effective performance in environments where temperatures range from -50°F to 700°F. Typical applications:

  • Steam Pipelines.
  • High Temp. Vessels.
  • Chemical Tanks.

Description

Fabreeka structural expansion bearings, or slide bearings, accommodate thermal expansion and structural rotation in buildings, bridges and pipe supports. Fabreeka designs and manufactures several types of expansion bearings for a wide range of applications, also including Teflon® bridge bearing pads. The expansion bearings are supplied as an upper and lower unit prepared to be tack or stitch welded in the field.

 

Fabreeka SBX type expansion bearings are used when construction tolerances, high load, and rotation are prominent with beam spans being excessive. This bearing is the most resilient in our full line of expansion bearings.

 

STX type slide bearings are used when construction tolerances and loads are moderate. This bearing has a very low coefficient of friction which is exceptional for use where expansion is large.

 

TTX type slide bearings are used as well when construction tolerances and loads are moderate. This bearing has a higher coefficient of friction than the STX Bearing and is used where the expansion criterion is limited.

 

Fabreeka slide bearings can be made with holes and slots, if required, to allow for mechanical attachment of expansion units to steel structures or for anchoring to concrete structures.

 

Fabreeka also offers GGX type expansion bearings made with graphite to achieve effective performance in high temperature environments.


Features and benefits:

  • Fabreeka SBX type structural expansion bearing is designed using Fabreeka-PTFE pad in the lower unit to accommodate large rotations and high reaction loads.
  • SBX type bearings meet AASHTO and State DOT specifications for fabric reinforced bearings pads with PTFE sliding surface.
  • TTX and STX type bearings can use a filled or unfilled PTFE surface as required.
  • For corrosive conditions, SBX, STX and TTX type slide bearings are available in stainless steel.
