Seiko (NSK) Co., Ltd. announced that it has developed high-speed angular contact ball bearings dry air compressor oil which is applied food, medical products and semiconductor manufacturing. The sale target of this product in NSK is 5 million yen in 2016 Development background: Dry air compressor oil used in the compression process, without the injection of oil to achieve compression. Since the compressor discharge air containing oil, they found that the use of the product and the environment, and the need to avoid contact with oil, in more and more applications. However, due to the fact that the structure of the compressor does not use oil to achieve the same level of efficiency, it requires three to five times the speed of the injection screw compressor, thereby reducing noise, vibration and energy consumption growing needs. In response to this demand, NSK developed in order to reduce the vibration of the motor using NSK's original cage material, L-PPS resin * 1 angular contact ball bearings. 1: a linear polyphenylene sulfide resin is a high-strength, having a high level of heat resistance. Product Features: (1) up to 40% reduction of vibration than the current item Vibration generating vibration of the bearing retainer in the process of high-speed operation of the main reasons. , The product is reduced cage vibration through the following modifications: Presentation L-PPS resin to achieve a significant amount of weight reduction compared to the current machining brass holder. Brass cage the same level of dimensional accuracy. Cage guide surface and the surface of the cage and the outer ring through the use of a special slot to maintain the improved lubrication of the outer surface of the frame. (2) compared to the current product up to 30% less in the bearing friction loss (torque). A major cause of bearing friction loss, keep the guide surface sliding friction between the frame and the outer ring. The new bearing cage guide surfaces halved, reducing the weight of the holder, to reduce bearing friction loss (torque) Product advantages: Low vibration and noise in high-speed operation Low energy consumption.
