Customers often ask that the guide rail slider they bought can not be installed on the linear guide rail. This problem is very key. If we do not solve this problem, similar problems will occur in the use process in the future. Then how can we solve this problem and what are the reasons for this problem? Let's have a brief understanding today.

導軌滑塊上面有強化型螺栓蓋，這種螺栓蓋的作用就是可以吸收加工誤差。利用0型環的彈性吸收螺栓孔徑因加工所產生的些微誤差，實現緊密的卡合效果。還有耐震動及耐磨型。利用0型環的吸振特性，避免螺栓蓋因線性滑軌受震動而產生脫落現象。還可以提升防磨性，通過提升與滑軌螺栓孔干涉量，并采用與滑軌螺栓孔全密封性設計，以實現高防塵性能。另外導軌滑塊還可以提升壽命。通過強化型螺栓蓋組裝后與滑軌上面平整性，可以避免刮油片毀損，進而提升線性滑軌的使用壽命。

There is a reinforced bolt cover on the guide rail slider. The function of this bolt cover is to absorb processing errors. The elasticity of the 0-ring is used to absorb some slight errors caused by the machining of the bolt hole diameter, so as to achieve a tight clamping effect. There are also vibration resistant and wear-resistant types. The vibration absorption characteristics of the 0-ring are used to avoid the falling off of the bolt cover due to the vibration of the linear slide rail. It can also improve the anti-wear performance. By increasing the interference with the slide rail bolt hole and adopting the full sealing design with the slide rail bolt hole, it can achieve high dust-proof performance. In addition, the guide rail slider can also improve the service life. Through the flatness of the reinforced bolt cover and the slide rail after assembly, the damage of the oil scraper can be avoided, and then the service life of the linear slide rail can be improved.

導軌滑塊裝不進滑軌上面還與它本身的預壓力也有關系，預壓大的一般需要調輕預壓以后才能裝進滑軌，另外導軌滑塊的鋼珠大小不一樣，同樣也會影響到裝不進去的問題。

The failure of the guide rail slider to fit into the slide rail is also related to its own preload. Those with large preload generally need to adjust the preload slightly before they can be installed into the slide rail. In addition, the steel ball size of the guide rail slider is different, which will also affect the problem of failure to fit.

就是每個不一樣也會出現這個問題，也就是說你能用A生產的滑塊去裝B生產的滑軌，因為它們自己本身的結構設計就不一樣。總之影響這個問題的有很多方面，我們可以根據平時自己使用過程中發現的方法來解決這些問題。

This problem occurs even if each brand is different, that is, you can use the slider produced by a to install the slide rail produced by B, because their own structural design is different. In short, there are many aspects that affect this problem. We can solve these problems according to the methods found in our daily use.
