QUALITY
ASSURANCE

KMP observes stringent quality surveillance plan for complete manufacture or repair of all bearings. Major checks include:

Testing of all raw materials for chemical composition and physical properties as per specifications.
 

Ultrasonic testing of base metal to ensure freedom from internal defects.
 
 

Precise control of all process parameters. Stage inspection at every stage of manufacturing.
 
 

Non-Destructive (Dye Penetration) testing for surface and edges against porosity or surface cracks as per ISO:4386/3 or equivalent and Ultrasonic testing for white metal bondage with backing material as per ISO 4386/1 or equivalent.

Destructive testing of integral cast specimen for absolute bond strength of white metal as per ISO:4386/II.

Precise dimensional control and inspection within closest tolerances as per engineering designs, concentricity/run-out, Lobe profiles, etc.

Dimensional control-peripheral length checking of thinwalled half bearings as per ISO 6524/BS 4480 : Pt.5 / ISO 3548

Custom designed packing to suit individual jobs.
