KEY FEATURES/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


Description

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.


FAQS

What do you recommend for an epoxy/adhesive to secure the Fabreeka-PTFE pad to the masonry plate? Fabreeka recommends #700 epoxy adhesive. Please see our Fabreeka #700 epoxy adhesive application sheet.


Are there installation instructions available? Yes. Please refer to our Fabreeka-PTFE bearing installation sheet.


When to I use an SBX, or TTX, or STX type expansion bearing? Please refer to our structural expansion bearing literature or contact Fabreeka’s Engineering department at 1-800-322-7352 or info@fabreeka.com for assistance.


What type/thickness PTFE should be used for the TTX and STX type bearings? The standard PTFE thickness is 3/32″ glass filled, etched on side for bonding. Other thicknesses/types are available upon request.


What is the maximum temperature that the SBX type bearing can be exposed to in a pipe slide application? The maximum temperature is 400°F.
