Għalkemm il-funzjonijiet tal-assi ottiku lineari u l-gwida lineari huma simili, it-tnejn huma ta 'appoġġ u gwida, iżda għad hemm xi differenzi bejniethom, prinċipalment fil-post tal-installazzjoni u l-forma. Mil-lat tal-forma, l-assi ottiku lineari huwa ċirkolari; filwaqt li l-gwida lineari hija ġeneralment kwadra u għandha pożizzjoni ta 'installazzjoni fissa li fuqha jiġi pproċessat is-slider.
From the installation point of view, the linear optical axis is generally fixed at both ends, and the suspended connecting parts in the middle cover all or most of the radial direction of the optical axis; but the linear guide rail is generally close to the equipment installation base on one side and fixed by bolts. of.
After reasonable cooperation, the linear bearing embodies the characteristics of light weight, corrosion resistance, interchangeability, and low cost. It is widely used in various machine equipment and can achieve the greatest economic benefits of labor saving and automation. Precision equipment or special machinery industries such as electronic equipment, food machinery, packaging machinery, medical machinery, printing machinery, textile machinery, machinery, instruments, robots, tool machinery, CNC machine tools, automobiles, and digital three-dimensional coordinate measuring equipment will use straight lines. Bearing.
In order to meet the needs of these different applications, the linear bearing specifications are also diverse, basically covering the LM and LME, LIN-11, LIN-12, and KH series. Among them, the LM series takes the metric size as the standard, and the linear shaft is equipped. The outer diameter tolerance is generally h7; while the LME series adopts inch sizes as the standard, and there are also metric sizes. The outer diameter tolerance of the linear shaft is generally g6.
The LIN-11 linear bearing is a European standard plastic linear bearing, which is installed with a circlip limit; and the LIN-12 series is a narrow design, and its outer diameter is directly installed in a tight fit with the mounting seat hole, mainly for saving Installation space.
