If these foreign particles are not removed from the rings, the dirt particles will distrupt the lubricating produce noise. Solid foreign particles lead to running noise, wear and premature failure. Hard particles in rolling bearings cause abrasive wear, particularly in contact areas with a high rate of sliding friction. Wear even occurs with extremely small particles. Cycling of larger particles (in the order of 0.1 mm) causes indentations in the raceways. The greater the hardness of the cycled particles (e.g. filedust, grinding chips, mould sand, corundum) and the smaller the bearings, the shorter the life.
The ultrasonic washing machine Karl Roll Model SK 03428 consists of a demagnetising unit, ultrasonic chamber and jet cleaning system. All are connected together with in-built conveyors. In the demagnetising unit, the rings are stacked and they are lifted upwards. When it is lifted upwards, a demagnetiser kept behind the component holder, demagnetises the component. The ring is then passed to the ultrasonic chamber where the washing media, mineral turnpentine is stored. The transducers create the ultrasound waves which makes the particles to get loosened. After this, the ring is taken up to jet cleaning system, where mineral turpentine oil is poured with a huge amount of pressure through nozzles/jets. Then the rings are free from magnetism and foreign particles.
Ultrasonic cleaning is the latest technology adopted for the bearing components cleaning all over the world, as the removal of foreign particles by forced clearing/brush cleaning cannot reach inside the component and still some amount of dirt particles will be retained."

2. Further examination of the entire manufacturing activity through Flow Process Chart of the item in question which has been placed before us to show that inner and outer rings are made free of foreign particles, then the process of demagnetizing takes places. Thereafter the process of ultrasonic cleaning is done besides the jet washing and thoroughly cleaned inner and outer rings. This is carried out for the following three purposes :-

The transducer is basically a lead-nirconate-titanate rings and sandwiched between two metallic blocks. When .........
