The central spring, made of stainless steel with very high characteristics, has the function of absorbing the small and medium undertow in harbors, greatly lightening the load generated by it so as not to stress the bollards as well, causing them to break, making the boat a unique and irreplaceable comfort. The new Hybrid nautical shock absorber does not have any components with welded details.To ensure the maximum quietness of our unique and patented shock absorber, all internal components slide on anti-friction inserts with a perfectly axial, long-lasting movement.The central elastomer increases the shock-absorbing capacity, intervening in adverse weather conditions and is assisted, subsequently, in case of strong stresses, by the lateral elastomers that enhance its absorption capacity.
