The ISB plants are specialized in the manufacture of radial ball bearings, tapered roller bearings, self-aligning roller bearings and needle bearings.


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.The material the ball-bearings are constructed with is not quite strong enough to withstand the physical and thermal loads exerted upon them, and 2.) the lubrication of the bearings is insufficient. It has been verifiably documented that some IMS bearings have failed after just 3,000 miles.
