Guideways TLR

The guideways of TLR series are unique in the world, telescopic system of the guideways having an opportunity to self-leveling. Self-leveling properties of the linear system allow to compensate the setting error of linear guideways working in pairs. TLR system provides unique opportunities and advantages for all types of automated applications with different stroke lengths

Rails of FXR series with the rollers

Depending on the working space and load ability, you can choose two sizes of the rollers - 43 and 63. Standard driving rollers - R*V series, floating rollers - R*P43 series or R*F43 series and R*F63 series for self-aligning system. For aggressive environments the rollers of stainless steel in 43 size are also available.

FXR rails

Dimensions guideway

The guideways are made of carbon alloy steel to provide the qualitative nitriding by T-RACE technology. A new hardening technology that is applied to the guideways is able to provide the surface hardness on a certain depth sufficient to provide the vibration resistance at the point of contact with the rollers, and also provide the protection against corrosion. After the nitriding rail is subjected to surface treatment by the oxide and impregnated with hot oil, which gives to the rail saturated black color, and high resistance to corrosion. The rail of NOX*FXR-P80 type is available with a step of mounting holes - 80mm for applications with the high loads.

Positioning of the roller installation rollers
load distribution

The roller must be installed in accordance with the direction of active load, and the number of rollers should be taken into account in accordance with declared load and system durability. Basically position of the roller is chosen in a such way that the active load will be in the radial direction - Co radial. An axial load Co - is the smallest load in magnitude, that is perceived by roller in comparison with the radial, so the axial load acts only at the one rail circulation path, and the radial is perceived by both of circulation paths simultaneously. The rollers must be mounted on the steel plates according to screw torques that are shown in the table below.

Each of the roller fixing screws has its own size of the installation key. During the mounting of sprags by the screws it's recommended to use the spring washers to facilitate the preload adjustment before final tightening of fixing screw.

Lubrication of the rails and rollers

A proper lubrication of the rails and rollers provides a long service life of the system, and high efficiency. In the cases to ensure a high efficiency of the system it's recommended to clean the circulation paths and rollers, and lubricate them after 100000 cycles for example, under the normal operating conditions. A manufacturer proposes to use a lubricant for precision products - "Classe NLGI2" (ISO2137)

Possible configurations of guideway systems with FXR rails.

FXR rails allow to create a variety of configurations of the linear motion systems that are made of 2 or more parallel rails mounted on the supporting beam or a profiled tube, on which rollers or sliders travel. Due to three circulation paths on the guideway, you can create a compact linear system. Below you can see the ready versions of systems that are produced by T-Race on request. Also, these systems can be assembled by the end consumer by using the components - FXR rails and rollers. Manufacturer can check and ensure the declared loads and moments in the request of these systems. The main advantage of the system - is that the solutions for the higher moments Mx can be easily mounted. Also, the linear system FXR can replace the monorail system by the installing of two parallel guideways.
