High resistance, they are particularly suitable for high speeds.That's why we find them in many mechanical applications. Ball bearings can be with or without seals (water and dust). Ball bearings with integrated seals contain a lubricant that is effective for life. These do not require maintenance.Our range is also composed of sealed ball bearings with, on both sides, sheet-reinforced acrylonitrile-butadiene rubber (NBR) contact seals. They are supplied ready for assembly and pre-greased.Deep groove ball bearings are simple in construction as well as easy to operate and maintain. They can run at high speeds and can support both radial and axial loads, furthermore they are robust, versatile and quiet running.How to choose a bearing from our CIXI GNYAR BEARING CO.,LTD ?
