Aluminum tin bearing technology

September 8, 2016 By Mike Santora

waukesha-aluminum-tin-bearing-postWaukesha Bearings continues its work in advanced material bearings with the application of aluminum tin (AlSn).

A drop-in replacement for babbitt tilt pads, AlSn-lined tilt pads provide higher load capacity than babbitt pads due to higher temperature capability and greater fatigue resistance. AlSn pads can operate at up to 60% higher loads than babbitt pads.

The benefit of the higher load capacity can be applied to upgrade equipment capacity within the same bearing envelope or to reduce the bearing size for lower power loss and greater equipment efficiency.

AlSn tilt pad thrust bearings are suitable in oil-lubricated applications, such as heavy duty gas turbines and high power density compressors that have design temperatures reaching 155°C (311°F) and/or cyclic bearing loads, which could result in babbitt fatigue.

Applications that require copper-free materials (which disqualifies babbitt and polymer-lined pads) can use AlSn-lined steel pads.
