The bush consists of two concentric sleeves with rubber securely bonded between them. Designed to accommodate torsional movement and axial and radial loads. The rubber is pre-stressed to give maximum dynamic strength and durability. The bonded rubber takes up full movement so lubrication or other bearing maintenance in not required. The bush has excellent sound and vibration isolation characteristics, enabling structures fitted with the Metalastik UD sleeve to be silent and vibration free.
