THK Linear guide rails, also known as linear guide rails, slide rails, linear guide rails, and linear slide rails, are used in linear reciprocating movements and can bear a certain torque to achieve high-precision linear motion under high load.

THK Linear guides (linear sliders) can be divided into: roller linear guides, cylindrical linear guides, ball linear guides, three kinds, used to support and guide moving parts, reciprocating linear motion in a given direction. Depending on the nature of friction, linear motion guides can be divided into sliding friction guides, rolling friction guides, elastic friction guides, fluid friction guides and other types.Need THK linear guide THK RSR12WZMUU



Self-aligning ability
The combination of DF (45- ° 45) ° from the arc groove, when installed, is due to the elastic deformation of the steel ball and the transfer of the contact point. Even if the installation surface is somewhat deviated, it can be absorbed by the inside of the rail slider. Produce the effect of self-aligning ability and get high precision and stable smooth movement.
Due to strict control of manufacturing accuracy, the size of the linear guide can be maintained within a certain level, and the slider has a retainer design to prevent the steel ball from falling off. Therefore, some series of precision are interchangeable. Customers can order the guide or The slider can also store the guide rail and the slider separately to reduce the storage space.
High rigidity in all directions
The use of four-row arc grooves, combined with a four-row steel ball and other 45-degree contact angle, allows the steel ball to reach an ideal two-point contact structure and can withstand the load from the up and down and left and right directions; it can be preloaded when necessary rigidity.Buy THK linear guide THK RSR12WZMUU


Working Principle
It can be understood as a rolling guide, which is an infinite rolling cycle between the steel ball and the slider, so that the load platform can easily move along the guide rail with high precision and linearity, and reduce the friction coefficient to the usual traditional sliding guide One fiftieth, can easily achieve high positioning accuracy. The design of the final unit between the slider and the guide rail allows the linear guide rail to withstand the load in all directions such as up, down, left and right. The patented recirculation system and simplified structure design make HIWIN's linear guide rail have smoother and lower noise movement.
 THK Linear bearings are mainly used in automated machinery, such as machine tools, bending machines, laser welding machines imported from Germany, etc. Of course, linear bearings and linear shafts are used together. Linear guides are mainly used in mechanical structures with high precision requirements. The moving elements and fixed elements of the linear guides do not use intermediate media, but rolling steel balls.
Use attention
Linear guides are precision parts, so they need to be used with great care. Even if high-performance linear guides are used, if they are not used properly, they will not achieve the expected performance results, and the linear guides are easily damaged. Therefore, the following items should be noted when using linear guides:
Prevent corrosion
When you take the linear guide directly by hand, you must fully wash off the sweat on your hands and apply high-quality mineral oil before operating. In particular, pay attention to anti-rust in the rainy season and summer.Click hear for THK linear guide THK RSR12WZMUU

Keep the environment clean
Keep the linear guide rail and its surrounding environment clean. Even tiny dust that is invisible to the naked eye can increase the wear, vibration and noise of the guide rail.
Install carefully
Linear guide rails must be carefully used during installation, do not allow strong punching, do not allow hammers to directly hit the guide rails, and do not allow pressure to be transmitted through the rolling elements.
The installation tool should be suitable
Use appropriate and accurate installation tools for linear guides. Use special tools as much as possible, and try to avoid using things such as cloth and short fibers.
