滾珠絲杠包括堅持架式或循環(huán)滾珠元件，以完成線性運動。它們的工作效率降低了90%，壽命可預測，即便在長時間運用中也能產(chǎn)生更少的熱量。它們是100%占空比應用和高速應用的理想選擇。取舍是滾珠絲杠執(zhí)行器。假如用于垂直應用，則需求制動。循環(huán)球也會產(chǎn)生很多可聽的噪音。滾珠絲杠執(zhí)行器能夠預加載，以提供所需的運用響應。為了減少磨損，延長螺桿的運用壽命，必需堅持螺桿的平穩(wěn)。

　　The ball screw consists of a stick or recirculating ball element for linear motion. Their efficiency is reduced by 90%, their life is predictable, and they can generate less heat even in long-term use. They are ideal for 100% duty cycle applications and high-speed applications. The trade-off is the ball screw actuator. If used for vertical applications, braking is required. The recirculating ball also produces a lot of audible noise. Ball screw actuators can be preloaded to provide the required operational response. In order to reduce the wear and prolong the service life of the screw, it is necessary to adhere to the stability of the screw.

　　滾珠絲桿的潤滑可選潤滑脂或潤滑油方式，而潤滑方法大致分為手動潤滑與自動強迫潤滑兩種，可依照系統(tǒng)的運轉(zhuǎn)速度，運用環(huán)境等需求做適宜的選擇有的環(huán)境可以運用鉬系等固體材料作為潤滑劑。詳情可以咨詢廣東索科潤滑油技術(shù)部。

　　The ball screw can be lubricated by grease or oil, and the lubrication method can be roughly divided into manual lubrication and automatic forced lubrication. According to the operating speed of the system, the application environment and other requirements, the appropriate choice can be made. In some environments, molybdenum system and other solid materials can be used as lubricating agent. For details, please consult Guangdong Soko lubricating oil technology department.

　　經(jīng)過油潤滑，應用條件足以構(gòu)成彈性流體動力學（EHD）潤滑膜也是關(guān)重要的。該薄膜將承載滾珠與滾道分開，防止金屬與金屬接觸。肯定潤滑膜能否有三個主要條件：潤滑劑的粘度，螺桿的速度以及滾珠和滾道之間的壓力。由于速度對EHD潤滑的影響，低速應用通常需求潤滑脂，在邊境潤滑（主要是金屬與金屬的接觸）或混合潤滑（金屬與金屬的接觸和組合）的條件下提供更好的潤滑支持。

　　After oil lubrication, the application conditions are enough to form EHD lubricating film. The film separates the bearing ball from the raceway to prevent metal to metal contact. There are three main conditions to confirm the lubrication film: the viscosity of lubricant, the speed of screw and the pressure between ball and raceway. Due to the influence of speed on EHD lubrication, low-speed applications usually require grease to provide better lubrication support under the conditions of boundary lubrication (mainly metal to metal contact) or mixed lubrication (metal to metal contact and combination).

　　絲桿所運用的潤滑劑，其粘度30~40cst(40℃）滑油運用ISO等級32~100，潤滑脂的給脂頻率根據(jù)運用條件與環(huán)境而有所不同，普通情形建議每運100KM的距離補充潤滑脂一次。

　　The lubricant used for the screw rod has a viscosity of 30-40 CST (40 ℃) and an ISO grade of 32-100. The grease feeding frequency varies according to the application conditions and environment. In general, it is recommended to supplement the grease once every 100 km.
