Aluminum Alloy Bearing Characteristics

Apart from the weight savings already mentioned UWE light alloy wire-race bearings are particularly advantageous in applications where the bearing is required to withstand shock loads and travelling vibrations. Due to aluminium’s smaller modulus of elasticity in comparison with steel and the additional elastic deformation between the races and race beds in the bearing rings, shock loads are absorbed much more smoothly, so that brinelling in the races and striation can be prevented.The high elasticity of the wrought aluminium alloy characterized by a low modulus of elasticity causes the elongation differential to be fully absorbed by the wire-race bearing.
