Fabreeka structural expansion bearings, or slide bearings, accommodate thermal expansion and structural rotation in buildings, bridges and pipe supports. Fabreeka designs and manufactures four types of expansion slide bearings for a wide range of applications. The expansion bearings are supplied as an upper and lower unit prepared to be tack or stitch welded in the field. For proper bearing design, several questions must be answered. Please download and fill out our expansion bearing questionnaire, or contact us with the following information: The maximum available bearing area depth, width and height.The maximum expansion expected and in which direction.The maximum load on each bearing.The maximum beam rotation in radians at the bearing area.If any slotsholes are required, a bolt pattern must be supplied.
