The guide rail can bear the fixed device or equipment guiding the movement and reduce its friction. In general, guide rails can be used in straight-line reciprocating motion occasions, such as guiding, fixing mechanical parts, special equipment, instruments and so on. The rolling guide rail has higher rated load than the linear bearing, and can bear a certain torque, which can realize high-precision linear motion under high load. Common guide rails are mainly divided into linear guide rails and roller guide rails. Compared with linear guide rail, roller guide rail is stable and can adapt to harsh environment.

具體區(qū)別如下：

The specific differences are as follows:

1、滾輪導(dǎo)軌的磨損較小，可以大大提高導(dǎo)軌和設(shè)備的使用壽命由于在相互運(yùn)動(dòng)的金屬材料之間如果不及時(shí)供給潤(rùn)滑油脂，就會(huì)產(chǎn)生更嚴(yán)重的磨耗問題，從而影響使用。所以潤(rùn)滑效果同樣是考量導(dǎo)軌系統(tǒng)好壞的因素之一。與直線導(dǎo)軌相比，滾輪導(dǎo)軌的接觸部分較小，而且是滾動(dòng)摩擦。因此只需要少量的潤(rùn)滑油就可以滿足使用要求。通常情況下滾動(dòng)導(dǎo)軌的潤(rùn)滑油補(bǔ)給周期為1個(gè)月，運(yùn)行長(zhǎng)度約100km。

1. The wear of the roller guide rail is small, which can greatly improve the service life of the guide rail and equipment. If the lubricating grease is not supplied in time between the moving metal materials, there will be more serious wear problems, which will affect the use. Therefore, the lubrication effect is also one of the factors to consider the quality of the guide rail system. Compared with the linear guide rail, the contact part of the roller guide rail is smaller, and it is rolling friction. Only a small amount of lubricating oil can meet the requirements. Generally, the lubricating oil supply cycle of rolling guide rail is 1 month, and the operation length is about 100km

2、滾輪導(dǎo)軌適用于高速運(yùn)動(dòng)，因?yàn)闈L輪導(dǎo)軌與直線導(dǎo)軌相比不容易產(chǎn)生摩擦熱，所以熱形變量很小，與直線導(dǎo)軌使用速度相差10倍以上。

2. The roller guide rail is suitable for high-speed movement. Because the roller guide rail is not easy to generate friction heat compared with the linear guide rail, the thermal shape variable is very small, which is more than 10 times different from the service speed of the linear guide rail.

3、滾輪導(dǎo)軌相比直線導(dǎo)軌要高。

3. The roller guide rail is higher than the linear guide rail.

4、滾輪導(dǎo)軌比直線導(dǎo)軌運(yùn)行要平穩(wěn)。

4. The roller guide rail runs more smoothly than the linear guide rail.

5、滾輪導(dǎo)軌可適應(yīng)惡劣環(huán)境。

5. Roller guide rail can adapt to harsh environment.

導(dǎo)軌的發(fā)展也就是直線運(yùn)動(dòng)系統(tǒng)的發(fā)展過程，工業(yè)導(dǎo)軌出現(xiàn)的是滑動(dòng)導(dǎo)向。但因?yàn)槠淠Σ磷枇^大、運(yùn)動(dòng)存在間隙、壽命低、潤(rùn)滑油使用量大等等原因很快就被淘汰掉。進(jìn)而衍生出滾輪導(dǎo)軌系統(tǒng)，它具有平穩(wěn)的運(yùn)動(dòng)系統(tǒng)，而且還能適應(yīng)惡劣環(huán)境。

The development of guide rail is also the development process of linear motion system. The first appearance of industrial guide rail is sliding guidance. However, it was quickly eliminated because of its large friction resistance, movement clearance, low service life, large amount of lubricating oil and so on. Then the roller guide rail system is derived, which has a stable motion system and can adapt to the harsh environment.
