Advantages and characteristics of Yintai linear guide rail


1. High positioning accuracy


When using a linear guide as a linear guide, due to the rolling friction mode of the linear guide, not only does the friction coefficient decrease to 1/50 of the sliding guide, but the difference between the dynamic friction force and the static friction force also becomes very small. Therefore, when the bed is running, there will be no slipping phenomenon, and the positioning accuracy can reach μ m level.


2. Low wear can maintain accuracy for a long time


Traditional sliding guidance inevitably leads to poor platform motion accuracy due to grease reflux, and insufficient lubrication during motion causes wear on the contact surface of the running track, seriously affecting accuracy. The wear of rolling guidance is very small, so the machine can maintain accuracy for a long time.


3. Suitable for high-speed motion and significantly reduces the required driving horsepower of the machine


Due to the very low friction force during the movement of the Yintai guide rail, only a small amount of power is needed to make the bed run, especially when the working mode of the bed is frequent back and forth operation, which can significantly reduce the power loss of the machine. And due to its low heat generated by friction, it can be suitable for high-speed operation.


4. Can withstand loads in all directions simultaneously


Due to the special constraint structure design of linear guides, they can simultaneously withstand loads in the up, down, left, and right directions, unlike sliding guides that can withstand lighter lateral loads in the direction of parallel contact surfaces, which can easily cause poor operating accuracy of the machine.


5. Easy assembly and interchangeability


When assembling, as long as the assembly surface of the guide rail on the milling or grinding table is milled or ground, and the guide rail and slider are fixed to the machine with specific torque according to the recommended steps, the high-precision during processing can be reproduced. Traditional sliding guidance requires scratching the running track, which is both laborious and time-consuming, and once the machine accuracy is poor, it must be scratched again. Linear guides have interchangeability, allowing for the replacement of sliders, guides, or even linear guide groups separately, allowing the machine to regain high-precision guidance.


6. Simple lubrication structure


If the lubrication of the sliding guide is insufficient, it will cause direct friction and wear of the metal on the contact surface of the bed. However, it is not easy to lubricate the sliding guide sufficiently, and it is necessary to drill holes at appropriate positions on the bed to supply oil. The linear guide rail is equipped with an oil nozzle on the slider, which can be directly filled with grease with an oil gun or connected to the oil supply pipe with a dedicated oil pipe joint for automatic lubrication of the oil supply machine.


Selection criteria


Precautions for using PMI rail MSA25LE-N linear rail:


（1） Pick up: 1. The slider and slide rail may fall down due to their own weight after tilting, please be careful.


2. Knocking or dropping the slide rail may not show any visible damage, but it may cause functional loss. Please be careful and cautious.


3. Please do not disassemble the slider by yourself, as it may cause foreign objects to enter or have adverse effects on assembly accuracy.


（2） Lubrication: 1. Please wipe the rust proof oil first before sealing it with lubricating oil (grease) for use.


2. Do not mix lubricating oils (greases) of different properties for use.


3. When using lubricating oil for lubrication, it may vary depending on the installation method. Please contact PMI first.


（3） Usage: 1. The ambient temperature should not exceed 80 ° C, and the instantaneous temperature should not exceed 100 ° C.


2. When disassembling or replacing the slider from the slide rail, please use a fake rail to assist in installation. Do not remove the slider from the slide rail unless necessary.


3. For use in special environments such as frequent vibration, high dust, high and low temperatures, please contact PMI.


（4） Storage: When storing linear slides, make sure to apply anti rust oil and seal them in the designated envelope. Place them horizontally and avoid high, low, and highly humid environments.
