The introduction is a linear motion system produced at low cost; it is used in combination with an infinite stroke and a cylindrical shaft. Because the bearing ball and the shaft are touched by a point, the load is small. The steel ball rotates with a very small frictional resistance; High-precision smooth motion.
Series standard type (LM/LME/LMB..UU), adjustment type (LM/LME..UUAJ), open type (LM/LME..UUOP), extended type (LM/LME..LUU), flange type (LMF/LMK/LMH. UU, LMEF/LMEK. UU), flange lengthening type (LMF/LMK/LMH.. LUU, LMEF/LMEK.. LUU) Center unit flange type (LMFC LMKC), belt Leading end flange type (LMF-E/LMK-E), KH simple type, OB self-lubricating type, LMC/LMG open type linear slider, etc.
The characteristic linear motion bearing is a linear motion system produced at low cost; it is used in combination with the infinite stroke and the cylindrical shaft.
Because the bearing ball and the shaft are touched by a point; therefore, the load is small. The steel ball rotates with a very small frictional resistance; thus, high-precision smooth motion can be achieved.
The most widely used series of standard types have three different scale series:
LM Series: Metric Scale Series (for Southeast Asian countries)
LME Series: Metric Scale Series (US)
Miniature habits are light, thin, and short. Bellows thieves school ≈ ≈ this frozen and ridiculous team school sea field foundation MM.
Stainless steel outer ring and steel ball cover are made of stainless steel; the holder is made of plastic.
The open type cuts a row of steel balls; and the corresponding outer ring; can obtain high rigidity; and avoids the guiding structure of the shaft warping; together, the gap can be adjusted; no loose cooperation.
LM...OP LME......OP
The gap adjustment type has a single slit type on the outer ring along the long axis; to adjust the outer casing of the fixed bearing to reach cooperation; no loose condition.
LM...ADJ LME...ADJ
The oil-sealed bearing has a special synthetic rubber sealing ring at one end or both ends. It is suitable for dust and foreign matter intrusion; and it can adhere well to smooth oil without leaking.
The strengths of the application. Because the active touch can make the starting friction resistance and the dynamic friction resistance extremely extreme. The silky tip of the silk is more beautiful.
. . . The load is increased; but the friction coefficient is not sensitive; therefore, the heavy load is increased; the friction coefficient is extremely high. (3) Page て诒 3 槐洌豢 槐洌豢 槐洌豢 槐洌豢 槐洌豢 没 褂 褂 褂 褂 倜て诒 倜て诒 3.
. . . Linear motion bearings have good interchangeability; the device is easy to replace and time-saving; and the mechanical layout is novel; small; light weight.
. . . Saving oil supply procedures; reaching the intention of simplifying smooth protection.
. . . Bearings with oil seals on both sides are also used to places with more dust or simple intrusion of foreign objects.
