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.


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.
