Cat® Bushes are commonly used to provide additional stretch length in a fastener to lower preload loss or to lower the cyclic stress range of machine operating loads. They are used to establish and maintain the functional relationship of dependent parts in machine systems. Cat® Bushes are cylindrical made of metal fixed to spread the pressure when tightened or to provide a standoff between two surfaces. Engineered with a specific application in mind, every Cat® Bush is designed and manufactured to exact tolerances to ensure proper alignment with existing systems on your Cat® Machine.
