Linear guides can perform reciprocating linear motion in a given direction. If determined by their conflicting nature, they can be divided into sliding conflicting guides, rolling conflicting guides, elastic conflicting guides, and so on.

通常在运转中会出现不良的情况。尤其是一些导轨间隙比较大，导轨就会向侧边摆动，这样滑块之间就会形成不良的噪音，因而，技术人员必须要对直线导轨轴承的“毛病信号”保持高度警惕，更好能够利用听觉辨识得出来。跟着直线导轨市场的需求量不断添加，其需求量也在不断上升，在运转过程中需要避免直线导轨发生毛病，然而，需要定时对直线导轨进行避免锈蚀的作业，并涂以矿物油后再进行操作。

Usually, adverse situations occur during operation. Especially when the clearance between some guide rails is relatively large, the guide rails will swing to the side, causing poor noise between the sliders. Therefore, technical personnel must be highly vigilant about the "fault signal" of the linear guide bearing, and it is best to use auditory recognition to identify it. With the increasing demand in the linear guide rail market, its demand is also constantly increasing. During operation, it is necessary to avoid problems with the linear guide rail. However, it is necessary to regularly carry out rust prevention operations on the linear guide rail and apply mineral oil before proceeding with the operation.

一，专用伸缩防尘罩

1、 Special telescopic dust cover

在使用环境恶劣的场所，有些型号备有专用软式伸缩防尘罩和专用防尘盖。详细内容和密封垫片标记的有关说明，请参照各种产品的相应任选配件（防尘）项目。

In harsh environments, some models are equipped with specialized flexible telescopic dust covers and specialized dust covers. For detailed information and instructions on sealing gasket markings, please refer to the corresponding optional accessories (dust proof) items for various products.

二，直线运动系统的专用密封垫片

2、 Special sealing gasket for linear motion system

为提高防尘能力，在各直线导轨系统中备有高耐磨损性的特殊合成橡胶制造的密封垫片，以及（层叠式接触刮板等）和清洁环等配件。

To improve dust resistance, special synthetic rubber sealing gaskets with high wear resistance, as well as accessories such as laminated contact scrapers and cleaning rings, are provided in each linear guide rail system.
