The diameter of pitch circle of bearing of Dmn value 〔 that development of favour ladder favour went to show performance of bearing high speed (Mm) × rotate speed coming back is spent (Rpm) 〕 reachs the area of 1.7 million gaskets horn contacts ball bearing. Dmn value and product photograph is compared before rose 20% , reach the whole world top level. As " BNFS " series product, stock the model of bearing internal diameter of 20 ～ 100mm. Can use at the main shaft that the machine tool such as machining center, tapper uses. The sale target of 2010 year is 1 billion yen / year. Stem from the consideration of wear respect normally, the high speed main shaft that Dmn value exceeds 1.4 million uses oily mist to lubricate etc oil-lubricated means. Oil-lubricated need undertakes on housing tubing is machined, outer perhaps ministry installs lubricant supply device. If use grease lubricant means, do not need these measure, so before this people hope to be able to lubricate in grease all the time high speed of the implementation below means is changed. Develop this " BNFS " series product optimized interior design, change scroll body diameter for example, so that the fall of bearing tigidity degree is controlled,be in minimal inside, make its won't rise considerably in the temperature when exceeding high speed to rotate at the same time. In addition, through using urea kind new-style grease " SE-1 " , prolonged the lubricant life of grease. Because be the sealed type bearing that takes gaskets, because this does not need to undertake bearing is cleaned and grease fills up wait for exercise, can reduce man-hour. Additional, as a result of need not exterior and lubricant device, because this can reduce cost. Lubricant means still has grease not to pollute environmental characteristic. CNC Milling CNC Machining
