ISB bearings are necessary when in a given machine or system, one structural part needs to rotate in the opposite direction to another along a fixed axis, whilst guaranteeing the axial and radial link between the two parts.


ISB is an entity made up of and structured on precise procedures, governed by a technical infrastructure for monitoring, as well as specialized personnel. Thanks to our Quality Control the certification process of our products is made with precise evaluation devices: pre-engagement questionnaires, visits to installations, compliance declarations, part sampling, analysis of supporting product documentation. Inbound production lots are checked daily, and supplier performance is monitored monthly. ISB constantly updates statistics relating to company procedures both in relation to technical-logistics-sales performance and customer satisfaction.
