Strict Quality Process Controls

Quality is built into many production processes with innovative “mistake-proofing” devices. Kilian systems are well documented and robust. The assembly process pictured below measures bearing components so the optimum ball size is selected. This optimized selection allows accurate control of the amount of play in the assembled bearings. Examples:
★ Optical comparators confirm component geometry
★ Electronic and other gauges conform to ANSI standards
★ Metallurgical, hardness and plating inspection
★ Bearing life cycle and durability testing
★ O.C. testing of all components before assembly
