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.

通常在運轉中會出現不良的情況。尤其是一些導軌間隙比較大，導軌就會向側邊擺動，這樣滑塊之間就會形成不良的噪音，因而，技術人員必須要對直線導軌軸承的“毛病信號”保持高度警惕，更好能夠利用聽覺辨識得出來。跟著直線導軌市場的需求量不斷添加，其需求量也在不斷上升，在運轉過程中需要避免直線導軌發生毛病，然而，需要定時對直線導軌進行避免銹蝕的作業，并涂以礦物油后再進行操作。

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，專用伸縮防塵罩

1、 Special telescopic dust cover

在使用環境惡劣的場所，有些型號備有專用軟式伸縮防塵罩和專用防塵蓋。詳細內容和密封墊片標記的有關說明，請參照各種產品的相應任選配件（防塵）項目。

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，直線運動系統的專用密封墊片

2、 Special sealing gasket for linear motion system

為提高防塵能力，在各直線導軌系統中備有高耐磨損性的特殊合成橡膠制造的密封墊片，以及（層疊式接觸刮板等）和清潔環等配件。

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.
