For the LINEAR GUIDE, LIMON is the biggest manufacture in China
LIMON set up business by producing LINEAR BUSHINGS, after years of development, we have owned a very good image and reputation in both domestic and overseas market. LINEAR BEARING is one of our strongest products, as a leading manufacturer in China, we have more than 20 years experience in the linear bearing manufacturing industry. LIMON linear bushing are of great quality, produced in our unique automatic workshop which is the first and only one in China. The size of our products widely range from diameter 4 up to 100mm, with various design versions. We also provide available options for diverse cage and coating.
We have 18 production lines, 45,000 square meters area currently, now the monthly capacity for blocks is 300,000pcs, for rails it’s 70,000 meters.
The block moves forward and backward along the fixed plane of the linear guideways, and the movement of the component is realized by fixing the special component on the block. Finally, realizing the whole movement through the circulation of the steel ball between the linear motion guide and the block. LIMON linear unit also use our own precision linear motion guide inside, and sell to all over the world.
What are features of linear guideways?
(1) High positional accuracy When a load is driven by a linear motion guideway, the frictional contact between the load and the bed desk is rolling contact. The coefficient of friction is only 1/50 of traditional contact, and the difference between the dynamic and the static coefficient of friction is small. Therefore, there would be no slippage while the load is moving. (2) Long life with high motion accuracy With a traditioal slide, errors in accuracy are caused by the counter flow of the oil film. Insufficient lubrication causes wear between the contact surfaces, which become increasingly inaccurate, In contrast, rolling contact has little wear;therefore, machines can achieve a long life with highly accurate motion. (3) High speed motion is possible with a low driving force Because linear guideways have little friction resistance, only a small driving force is needed to move a load.This results in greater power savings, especially in the moving parts of a system. This is especially true for the reciprocating parts. (4) Equal loading capacity in all directions With this special design, these linear guideways can take loads in either the vertical or horizontal directions. (5) Easy installation Installing a linear guideway is fairly easy. Grinding or milling the machine surface, following the recommended installation procedure, and tightening the bolts to their specified torque can achieve highly accurate linear motion. (6) Easy lubrication With a linear motion guideway, grease can be easily supplied through the grease nipple on the linear guideway block. It is also possible to utilize a centralized oil lubrication system by piping the lubrication oil to the piping joint. (7) Interchangeability Compared with traditional boxways or v-groove slides, linear guideways can be easily replaced should any damage occur. For high precision grades consider ordering a matched, non-interchangeable, assembly of a block and rail.
How is the precision grade of linear guideways divided? Linear guide is a precision transmission accessories, its precision directly affects the precision of the equipment. Generally speaking, the accuracy refers to the walking parallelism of the upper table of the block facing the lower surface of the slide rail, and the grade is divided into (take the guide rail as an example). — General grade (C/N) 5μm — Advanced (H) 3μm — Precision grade (P) 2μm — Ultra-precision grade (SP) 1.5μm — Ultra Ultra Precision (UP) 1μm The precision data of linear guideways is distinguished from the value of several indicators, specific can click”
