Product Description

MGN type miniature linear guideways

Slider-the movement is transformed from a curve to a straight line. The new guide rail system enables the machine tool to obtain rapid feed speed. In the case of the same spindle speed, rapid feed is a characteristic of linear guides. Linear guides, like flat guides, have two basic elements; one as a guide is a fixed element, and the other is a moving element. Since the linear guide is a standard component, it is for machine tool manufacturers. The only thing to do is to process the plane of a mounting rail and adjust the parallelism of the rail. Of course, in order to ensure the accuracy of the machine tool, a small amount of scraping of the bed or column is essential. In most cases, the installation is relatively simple. The guide rail as a guide is hardened steel, which is placed on the installation plane after fine grinding. Compared with flat guide rails, the cross-sectional geometry of linear guide rails is more complicated than that of flat guide rails. The reason for the complexity is that grooves need to be machined on the guide rail to facilitate the movement of sliding elements. The shape and number of grooves depend on the completion of the machine tool. Function. For example: a guide rail system that bears both linear force and subversive moment is compared with a guide rail that only bears linear force. The design is very different.
The basic function of the fixed element (guide rail) of the linear guide system is like a bearing ring, the bracket for mounting the steel ball, the shape is "V" shape. The bracket wraps the top and both sides of the guide rail. In order to support the working parts of the machine tool, a set of linear guide has at least four supports. Used to support large working parts, the number of brackets can be more than four.
When the working parts of the machine tool move, the steel balls circulate in the groove of the bracket, and the wear of the bracket is distributed to each steel ball, thereby prolonging the service life of the linear guide. In order to eliminate the gap between the bracket and the guide rail, the preload can improve the stability of the guide rail system and the preload can be obtained. It is to install an oversized steel ball between the guide rail and the bracket. The diameter tolerance of the steel ball is ±20 microns in increments of 0.5 microns. The steel balls are screened and classified and installed on the guide rails respectively. The size of the preload depends on the force acting on the steel balls. If the force acting on the steel ball is too large and the preloading time is too long, resulting in increased stent movement resistance, balance problems will occur; in order to improve the sensitivity of the system and reduce the movement resistance, the preload should be reduced accordingly , And in order to improve the accuracy of the movement and the retention of the precision, it is required to have enough pre-adding negative numbers, which are two contradictory aspects.
If the working time is too long, the steel ball begins to wear, and the preload on the steel ball begins to weaken, resulting in a decrease in the movement accuracy of the working parts of the machine tool. If you want to maintain the initial accuracy, you must replace the rail bracket or even the rail. If the guide rail system has a preload effect. The accuracy of the system has been lost, and the only way is to replace the rolling elements.
The design of the guide rail system strives to have the largest contact area between the fixed element and the moving element. This not only improves the carrying capacity of the system, but also the system can withstand the impact force generated by intermittent cutting or gravity cutting, spread the force widely, and expand the bearing capacity. The area of force. In order to achieve this, there are various groove shapes for the guide rail system, and there are two representative ones, one is called Gothic (pointed arch), the shape is the extension of a semicircle, and the contact point is the apex; the other The species is arc-shaped and can also play the same role. No matter what kind of structure, there is only one purpose, and strive to have more rolling steel ball radius contact with the guide rail (fixed element). The factor that determines the performance characteristics of the system is: how the rolling elements contact the guide rail, which is the key to the problem.

Specification :

The new RG series from Hiwin features a roller as the rolling element instead of steel balls. The roller series offers super high rigidity and very high load capacities. The RG series is designed with a 45-degree angle of contact. Elastic deformation of the linear contact surface, during load, is greatly reduced thereby offering greater rigidity and higher load capacities in all 4 load directions.The RG series linear guideway offers high performance for high-precision manufacturing and achieving longer service life.

Rolling circulation system: Block , Rail , End cap , Circulation path, rollers

Lubrication system: Grease nipple and piping joint

Dust protection system: End seal, Bottom seal, Cap, Double seals and scraper

Key Features :

1.Built-in long life lubrication

2.High positional accuracy

3.High speed motion is possible with a low driving force

4.Equal loading capacity in all directions

5.Easy installation

6.Inter change ability

Advantages :

(1) Optimal design

fEM analysis was performed to determine the optimal structure of the block and the rail. The unique design of the circulation path allows the RG series linear guideway to offer smoother linear motion.

(2) Super high rigidity

The RG series is a type of linear guideway that uses rollers as the rolling elements. Rollers have a greater contact area than balls so that the roller guideway features higher load capacity and greater rigidity.

(3) Super high load capacity

With the four rows of rollers arranged at a contact angle of 45-degrees, the RG series linear guideway has equal load ratings in the radial, reverse radial and lateral directions. The RG series has a higher load capacity in a smaller size than conventional, ball-type linear guideways.

(4) Operating life increased

Compare with the ball element, the contact pressure of rolling element is distributed on the line region. Therefore, stress concentration was reduced siginificantly and the RG series offers longer running life. The nominal life of RG series can be calculated by using Eq.
