    Daring class destroyers foremast top of the rotating radar antenna placed in the Royal Navy s newest bearings must withstand vibration and flip load. In the salt spray environment, the flip load may caus e parts of dumping and reduce the reliability of the radar.bearing manufacturers
    The radar manufacturer Alenia Marconi Systems Ltd. engineers and the Timken Company with cross-roller bearings to support and rotate the SAMPSON multifunction radar. Timken s chief process engineer Tom Baker said the bearings 3 m in diameter than the diameter of their manufacturing this type of bearing, 1/3.

    The cross roller bearing is mainly composed by two plain bearings. A fixed angle formed between the roller. This design allows the bearings to withstand the limit is much higher than ordinary single-bearing rack. However, each composed of two sub-bearing cross-bearings the load center (the roller axis and the vertical line through the bearing central intersection) has great support surface, higher than bearing the physical depth of a lot, makes bearing the anti-flip performance is improved.china bearing manufacturer
