Do you have a Bolted Connection?
Farrat offer several accessories to optimise isolation performance:
- Anti-Vibration Washers
- Bushes
Our engineering capabilities allow us to help you choose the right elastomeric materials for your application.
Our range of vibration isolation elastomers are manufactured in the UK and distributed worldwide across a wide range of construction projects. We are proud of the high performance these materials have provided our customers in their applications.
Material properties such as stiffness, dynamic stiffness, damping, load bearing capacity, shape factor, creep and hysteresis are continually tested in our R&D facility to provide an assured performance. We operate under an ISO 9001:2015 Quality Assurance System and under the international ISO 14001:2015 Environmental Management Standard.
