Load ratings and speeds, where recommended in the catalog, have been based on experience in relating laboratory over-speed endurance tests with field experience and should assure satisfactory operation in most applications. Bearing performance should be thoroughly evaluated either on a prototype or actual working unit for bearing performance, loading, noise and vibration characteristics. KMS bearings are manufactured to generally considered normal commercial tolerances and if properly applied should provide satisfactory operation. Our warranty covers materials and workmanship only. In the event that a defect in workmanship or materials is found within 30 days from receipt of the shipment, the extent of KMS’ liability will be replacement of the product only. Since the bearing is only a component of the unit and satisfactory bearing performance is dependent upon the design parameters of the unit in which it is used, the suitability of the correct KMS bearing is the responsibility of the customer.
