Product Description

LMEK-UU Flange Linear Motion Bearing with Ball

The square flange type linear bearing mainly consists of sleeve, ball, seal, nylon cage and square flange. Among them, the flange plays a fixing role. During installation, the coordinated equipment should have high bore accuracy.
The product is finely processed enjoying low coefficient of friction. This also allows it make almost no noise during working. Due to the reasonable design, the flange has good stability. In addition, the product also features high working accuracy. With easy replacement, it has been widely used in CNC machine tools, printers, power tools, sports equipment, multi-axis machine tools, and so on.
The sub-categories of this product are almost similar in the appearance and functionality. However, LMK, LMEK, and LMBK series are produced in accordance with the standards in Asia, Europe, and the Americas. With a wide range of size selection, it can be suitable for different machines. In addition, UU type is a common square flange type linear bearing, while the LUU type refers to the lengthened one.
The LMK-UU square flange linear bearing available in the metric size can be commonly found in the Asian market.

As a professional standard linear bearing manufacturer and supplier in China, we also offer adjustable type linear bearing, round flange mount linear bearing, SC-UU slide block, SHF horizontal shaft support, and much more.
 
The LM-UU linear motion bearing is manufactured in line with Asia's mechanical standards, so that it is suitable for use in Asia. The products we offer include many models with the applicable shaft nominal diameter ranging from 3mm to 150mm. They differ in the main dimensions and tolerances, the degree of eccentricity, the maximum radial clearance, and the rated load. Therefore, this linear bearing for Asia market can be used in different sizes and models of machinery, serving to reduce friction and extend life of the equipment.
