Linear bearing is the self-lubricating characteristic of a linear motion system. The difference between linear metal bearing and linear metal bearing is that the linear metal bearing is rolling friction, and the bearing and cylindrical shaft are point contact, which is suitable for low load and high-speed motion; while the linear plastic bearing is sliding friction, and the bearing and cylindrical shaft are surface contact, so this is suitable for high load medium and low-speed motion. We want to make the linear bearing work better, then we must maintain it! Next, the guide screw manufacturer will explain the main maintenance items of the linear bearing in detail for you:

　　我們必須注意維護(hù)時(shí)的線(xiàn)性軸承維護(hù)不同的軸承是不一樣的:金屬直線(xiàn)軸承維護(hù):潤(rùn)滑和摩擦,線(xiàn)性軸承內(nèi)部注入防腐油,如果使用油脂潤(rùn)滑,一個(gè)用煤油或有機(jī)溶液去除防腐油,空氣干燥,然后添加潤(rùn)滑脂。(建議使用粘度標(biāo)記為N0.2的鋰皂潤(rùn)滑脂)潤(rùn)滑時(shí)不需要去除防銹油，根據(jù)溫度變化可選擇粘度等級(jí)為ISO vg15-100的潤(rùn)滑油。由于密封圈會(huì)刮油，油潤(rùn)滑不適合有密封圈的無(wú)孔軸承。塑料直線(xiàn)軸承的保養(yǎng):由于塑料直線(xiàn)軸承的滑動(dòng)膜是由自潤(rùn)滑塑料制成，所以在使用過(guò)程中不需要額外的供油和保養(yǎng);而且由于塑料直線(xiàn)軸承帶有切屑槽，所以即使軸承或軸上擠滿(mǎn)了灰塵也不需要保養(yǎng)，灰塵在運(yùn)動(dòng)過(guò)程中會(huì)自動(dòng)從切屑槽中移出;只有當(dāng)滑動(dòng)膜磨損時(shí)，才能直接更換內(nèi)滑動(dòng)膜。易于維護(hù)。

　　We must pay attention to the maintenance of linear bearings. The maintenance of different bearings is different: maintenance of metal linear bearings: lubrication and friction. Anti corrosion oil is injected into the linear bearings. If grease lubrication is used, the first one is to remove the anti-corrosion oil with kerosene or organic solution, air drying, and then adding grease. (it is recommended to use lithium soap grease with viscosity marked N0.2) when lubricating, rust proof oil does not need to be removed, and lubricating oil with viscosity grade of ISO vg15-100 can be selected according to temperature change. Because the sealing ring will scrape oil, oil lubrication is not suitable for the bearings with sealing ring. Maintenance of plastic linear bearing: since the sliding film of plastic linear bearing is made of self-lubricating plastic, no additional oil supply and maintenance are required in the use process; moreover, since the plastic linear bearing has chip groove, even if the bearing or shaft is full of dust, no maintenance is required, and the dust will be automatically removed from the chip groove during the movement process; Only when the sliding film is worn, can the inner sliding film be replaced directly. Easy to maintain.
