The unrestrained expansion joint (EJ) is simply a bellows element attached to end fittings used to handle movements resulting thermal expansion or contraction of the adjacent piping. The single unrestrained expansion joint is the most basic Expansion Joint type, and can be used as the starting point once the need for an EJ has been established. It is the most economical EJ product. However, the unrestrained EJ imposes pressure thrust force and deflection spring forces on adjacent anchorage and those forces must be accommodated by the system designer. Also, the amount of lateral offset is limited by the bellows length and often times the bellows length is severely limited by column stability

The amount of lateral offset that can be accommodated is only limited by the distance between the bellows elements and the overall length of the assembly. The separation of the bellows elements also results in a very low lateral offset spring rate. Just like the single, the unrestrained universal EJ imposes pressure thrust forces on adjacent anchors
