滚珠丝杠包括坚持架式或循环滚珠元件，以完成线性运动。它们的工作效率降低了90%，寿命可预测，即便在长时间运用中也能产生更少的热量。它们是100%占空比应用和高速应用的理想选择。取舍是滚珠丝杠执行器。假如用于垂直应用，则需求制动。循环球也会产生很多可听的噪音。滚珠丝杠执行器能够预加载，以提供所需的运用响应。为了减少磨损，延长螺杆的运用寿命，必需坚持螺杆的平稳。

　　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.

　　滚珠丝杆的润滑可选润滑脂或润滑油方式，而润滑方法大致分为手动润滑与自动强迫润滑两种，可依照系统的运转速度，运用环境等需求做适宜的选择有的环境可以运用钼系等固体材料作为润滑剂。详情可以咨询广东索科润滑油技术部。

　　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.

　　经过油润滑，应用条件足以构成弹性流体动力学（EHD）润滑膜也是关重要的。该薄膜将承载滚珠与滚道分开，防止金属与金属接触。肯定润滑膜能否有三个主要条件：润滑剂的粘度，螺杆的速度以及滚珠和滚道之间的压力。由于速度对EHD润滑的影响，低速应用通常需求润滑脂，在边境润滑（主要是金属与金属的接触）或混合润滑（金属与金属的接触和组合）的条件下提供更好的润滑支持。

　　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).

　　丝杆所运用的润滑剂，其粘度30~40cst(40℃）滑油运用ISO等级32~100，润滑脂的给脂频率根据运用条件与环境而有所不同，普通情形建议每运100KM的距离补充润滑脂一次。

　　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.
