Round Flange Linear Bearing LMEF Series
The LMEF type linear bearing is a metric dimension series generally used in Europe. It has a round flange with a bushing bearing as a whole, has other four components, outer sleeve, retainer, steel ball and seal ring. And the corresponding components make the axial positioning simple. It does not need to be fixed in the matching bearing pillow blocks like the non flange linear bearing. It becomes very economical and time-saving, and it has also reduced the overall weight of the linear bearing assembly as well as smoothed the operation.
Linear bearing LMEF series unlike ball bearings, the basic static load rating of LMEF circular flange linear bearings is greater than the basic dynamic load rating, and as the size increases, this value gap continues to expand, even up to 2 times. The linear bearing can run stably and quietly with little friction and high precision. In addition, it can also be easily replaced, which brings convenience for the user.
Application
Linear bearings are used widely in electronic equipment, pull tester and digital three-dimensional coordinate measuring device. Such as precision equipment, as well as multi-axis machine tools, press tool, grinder automatic gas cutting machine, printer, card sorting machine, food packaging machine and other industrial machinery sliding components.
