The linear motion ball bearing has a layout in which an adherer is installed in the outer ring; the adherer is equipped with a plurality of steel balls; and the infinite circulation motion is performed; the two ends of the holder are fixed by the inner spring retaining ring; the straight line in each steel ball is subjected to the force operation The track side is provided with a notched window.
Some of these are to make the loaded steel ball and the shaft roll and touch. Relatively move with a very low friction coefficient; therefore, the linear motion ball bearing is the most suitable bearing for mechanical equipment, automation equipment, energy-saving equipment, etc. Linear motion bearing; It is used more and more widely in the general or special machinery industry such as electronics, machinery, instruments, robots, machinery, food machinery, packaging machinery, medical machinery, printing machinery, textile machinery, CNC machine tools, automobiles.
The advantages of using linear motion ball bearings: 1. Because the active touch can make the starting friction resistance and the dynamic friction resistance extremely extreme. The more the silk tip is the more the 谑∧ 谑∧ 谑∧ 玫 玫 玫 玫 玫 玫 玫 玫. The load is increased; but the friction coefficient is not sensitive; therefore, under heavy load; the friction coefficient is extremely.

Linear motion bearings have good interchangeability; the device is easy to use and time-saving; and the mechanical layout is novel; small; light weight features. Saving oil supply procedures; reaching the intention of simplifying smooth protection. Bearings with oil seals on both sides are also suitable for places with more dust or simple intrusion of foreign matter.
Classification of linear motion ball bearings: The standard most widely used series has three different scale series: LM series: metric scale series (for Southeast Asian countries), LME series: metric scale series (for US). l micro habits light and thin , short. Bellows thieves school, this frozen and ridiculous team school 3, 4, 5MM.l stainless steel outer ring, steel ball two caps are stainless steel; adhere to the choice of plastic production. S; SL...... UU l open type cuts a row of steel balls; corresponding to the outer ring; can obtain high rigidity; and avoid guiding structure of shaft warping; together can obtain gap adjustability; no loose cooperation condition. LM...OP LME......OP l The gap adjustment type has a single slit type on the outer ring along the long axis; to adjust the outer shell of the fixed bearing to cooperate; no loose condition. LM...ADJ LME...ADJ l oil seal type bearing single or double end with lip shape There is a special synthetic rubber sealing ring; it is suitable for dust and foreign matter intrusion; and it can adhere well to smooth oil without leaking.
