NSK is a global leading supplier of bearings, automotive components and steering systems, precision and mechanical products. It also owns RHP. NSK have developed a range of quieter-running cylindrical roller bearings aimed specifically at the electric motor market. This development has been as a result of ever increasing pressure from motor manufacturers to produce quieter-operating, energy efficient electric motors. Nsk bearing is used in vehicle chassis, forming machine tools, steel metallurgical machinery, mineral mountain machinery, hydraulic industry and rolling steel industry, etc. The material of this product is based on stainless steel plate with a sintered porous bronze layer as its interlayer which is coated with the compound of PTFE on its surface. The material is without PB. It's used in foodstuff machines, pharmaceutical machines, printing and dyeing machines, etc. This new EM range of cylindrical roller bearings from NSK can provide a real advantage in applications where noise and vibration is an issue. NSK Explorer range bearings utilize advanced steel technology and industry leading designs to produce a bearing that can last up to three times longer than NSK previous market-leading products. This NSK patented range is now available across most types of bearings from Antifriction Components and can provide real savings against similar products.
