IKS USA Facilities - Quality Assurance

The NOMA IKS Corp. facility in Gardena, CA is the final step in ensuring we deliver a world class quality bearing product. Our USA facility allows us to provide our customers maximum flexibility in their selection of the exact end-variant bearing configuration required with essentially off-the-shelf product availability . 

Both our Japanese and Chinese bearings are imported from the factory without grease, seals or markings. Upon arrival at the IKS facility in Gardena, CA, each bearing is washed in automated machinery, grease lubricated, capped with rubber seals or metal shields, and then laser marked for identification, all per customer specifications. Finally, the bearings are thoroughly tested for dimensional conformance, noise and vibration, and internal radial clearance using the latest test equipment and SQC procedures per the IKS ISO 9002 registered quality systems. A written quality assurance report is available upon request for each shipment of bearings to customers.
