The micro linear bearing purposes

Linear ball bearings is its structure within the outer ring is equipped with retainer, retainer is equipped with multiple steel ball, and infinite loop movement. Retainer spring collar within fixed on both ends, in the steel ball bearing work straight track side have a gap in the window. This part is made of steel ball by load rolling contact. Relative movement with very low friction coefficient, so linear ball bearings for machinery and equipment, automation equipment, energy-saving equipment such as the most appropriate selection of bearings. Linear motion bearings, is being more and more widely applied to electronics, machinery, instrument, robots, tools, machinery, food machinery, packaging machinery, medical machinery, printing machinery, textile machinery, CNC machine tools, automobile and other general or special machinery industry. Due to the current contact can make the starting friction resistance and friction resistance is tiny, so you can save energy, easy to get a high speed. The load increase, but the friction coefficient is not sensitive to changes, so under heavy load, small friction coefficient, and the accuracy unchanged for a long time, can be mechanical service life is long. Linear motion bearings good interchangeability, easy installation and use to save time, and make the mechanical structure is novel, small, lightweight characteristic. Save for oil formalities, simplifies the lubrication and maintenance. 5. On both sides of additional oil seal bearing also apply to dust more easily invaded by a foreign body or places. The classification of the linear motion ball bearings, standard series of the most widely used three kinds of different size series: LM series: metric size series ( Association of southeast Asian nations) ; The LME series: metric size series ( The United States use) 。 L miniature to adapt to the light, thin, short, needs of The Times series, the ultra small diameter size, inner diameter: 3, 4, 5 mm. L stainless steel blocks are all stainless steel on both ends of the outer ring, steel ball, retainer plastic manufacturing. UUl open resection of a column of steel ball, and corresponding to the outer ring, can obtain high rigidity, and prevent the warping of the shaft guide, adjustable gap can be obtained at the same time, no loose fit. An OPl clearance gather along the long axis on the outer ring to open a single slit type, to adjust fixed bearing shell to cooperate, no loose state. ADJl enclosed type oil seal bearing single side or both ends with a lip with special synthetic rubber sealing ring, more suitable for dust and foreign bodies into place, and can be a very good keep lubricating oil leakage.
