Extend the maintenance cycle in high-temperature environments such as solar cell and LED production~ Nippon Seiko Co., Ltd. (headquarters/Tokyo Shinagawa-ku, director representative executive director Norio Otsuka, hereinafter referred to as NSK) has developed a low-exhaust , Solid lubricating coated bearings with superior durability. NSK is expected to produce solar cells, LEDs and other global manufacturing bases in China, Taiwan and South Korea as the center of sales, and by 2015, annual sales will reach 1 billion yen. [Development background] In order to obtain high-quality and high-yield solar cells, LEDs, lithium-ion batteries, etc., they need to be produced in a clean environment. Especially in the film formation and sintering process in a high-temperature clean environment, it cannot be used because oil such as grease or the binder contained in the solid lubricating coating will emit gas. In cases other than high-end equipment, non-lubricated bearings with a short life can only be frequently replaced, and the ensuing problem of extending the life of the bearing has become a major research topic. NSK has developed solid lubricating coated bearings that have the same low outgassing characteristics as conventional non-lubricated bearings but have a life span that is 8 times longer by employing solid lubricating coating technology that has superior durability at high temperatures on steel balls. *1 Binder: A material (resin, etc.) that improves the adhesion between the base material and the solid lubricant. *2 Exhaust: Gas released from organic substances, etc. [Features] No adhesive is used for reasons such as exhaust, and a self-developed solid lubricating coating that improves adhesion to the base material is used. It has the following characteristics. (1) Under the high temperature environment below 400 ℃, the service life is extended up to 8 times compared with the non-lubricated bearing. (2) It has the same low outgassing performance as the non-lubricated bearing. [Product effect] Under high temperature conditions such as film formation and sintering in solar cell production, the maintenance cycle is extended and productivity is improved. NSK aims to perfect the special environment series products, and constantly develops high-performance products to meet the needs of users in various industries.
