Domestic THK AQ12mm Linear motion guide

First. Product Characteristics

    Linear rolling guide composition by slippery course, slider,steel boll,return to implement, note oil cup, seal etc.

  When linear guide work. The shot scroll between the slippery course which using high quality alloy steel and the slider, through the high hardness processing and dense forming grinding machining and into the groove of rolling, through the slider to implement make both ends reflux of infinite circular motion, make the slider easily to do high precision linear motion along the slippery course . Compared with the traditional sliding guide, rolling guide of the friction coefficient can reduce to 1/50 of the original , due to start the friction decrease greatly, relatively less invalid, so movement occurs easily achieve μm class feeding and positioning. Plus there is a bind unite between the slider and guideway , making the beam design linear guide-orbit can assume certain torque, and bear the up and down and so on various direction load.

 Return to the device equipped with dust-proof sealed cover both ends, can effectively prevent the dust, denitration end into the slider internal. Linear guide lubrication, through the note oil cup infuse lubricant to complete.

1.Work precision

    Linear guide movement by the scroll to realize, not only the sliding friction coefficient reduced to 1/50 of guide rail, dynamic and static friction resistance gap also become small, realize smooth movement, reduce impact and vibration, not easy to generate creep phenomenon, the UM level can achieve feeding and positioning accuracy, be beneficial to improving the response speed and sensitivity  of CNC coefficient.

2.Slash drive rate

   Due to the friction is very small when the linear guide is motion, only request small power, can the movement, the obvious greatly machine power wastage, and because of friction heat rarely, is suitable for high-speed, frequent start-up and reversing the motion component.

3.Lubrication simple structure

    Linear guide on the slide block with the note oil cup, which can be directly to note oil injection grease, can also link for tubing for automatic injection machine lubrication, make its abrasion drop to less, the long time keeping pure held.

4.Dustproof, sealing ability

  Linear guide dustproof performance is good, slide block with sealed cover both ends, bottom can choose seal negative, meanwhile slippery course screw holes with dustproof, prevent the dust cover screw holes of accumulation, thereby ensuring life and performance of products. 

5.Easy installation, easy swap

Due to the use of sophisticated processing technology, slippery course linear degree is high, the installation of screw holes in slippery course error less, convenient installation, linear guide interchangeable, respectively replace the slider or the slider even linear guide, can make to achieve high precision machines.

6. Carrying capacity and rigidity is strong

    Linear guide adopted gothic four-point contact design, reasonable ratio of arc groove, not only the contact stress of small, load capacity and rigidity of relative v-shaped plane ball contacts also greatly enhanced. Because of the copper ball by symmetrical four beam system, may simultaneously carried by around each direction load, and almost no offset phenomena occur, so rigid stronger can maintain precision
