Seiko Co., Ltd. Shandong Bot precision grade guide is divided into ordinary level (no label / C) 5μm High (H) 3μm precision grade (P) 2μm Super precision (SP) 1.5μm Ultra precision grade (UP) 1μm Shandong Bo deputy and deputy distinguish ball linear guide roller linear guide special Seiko Co., Ltd. mainly two things: one, different sports media. Ball linear guide, it is a ball sport media, sports media guide roller is a direct line roller (cylindrical roller). 2, carrying different sports media roller linear guide surface rolling contact with the line, the ball linear guide sports media to the point of rolling contact surface, so the roller linear guide bearing capacity stronger. Of course, due to the different media movement, two guide structures are different, the slider structure naturally different. Linear Rolling Guide development linear guides "in the" "developed on the basis of" Rolling Rolling "was born in 1907 in the Swedish company SKF, which set off a wave of rolling industry. Mr. Gu Laiqie according to German scientists." Rolling "principle invented the most primitive linear guides Changzhi linear guide enterprises to obtain French patent in 1932, but it was a small rolling linear guideway load, assembly complex, high failure rate, he was influenced widely used. It was at This stage linear guides, synthetic resin "sliding rails," made a breakthrough development, the more delayed the development of linear guides. to the 1970s, with the mechanical linear guide NC Changzhi supply of high-speed, high-precision , high-performance requirements are also increasing, "slide rail" has been powerless Changzhi linear guide price "rolling guide" officially came into being In 1973, the maturity of linear guides successfully developed in Japan and onto mass production process. Chinese Vice rolling linear guide development began in the early 1980s, so far only the history of 30 years. Changzhi linear guide Supply linear guide _ _ Shandong by Shandong Bot Bot Seiko Seiko Co., Ltd., Shandong Bot Seiko Co., Ltd.
