滾珠絲杠·支撐裝置技術窗口想發揮絲杠的性能，選對支撐座是關鍵Ball Screw-Support Unit

　　To fully utilize the performance of the ball screw and support device, selecting the right support seat is crucial. Ball Screw Support Unit

　　絲杠支座組件的構成：在滾珠絲杠上，藏著一個默默發力的“幕后英雄"- 絲杠支座組件。你可能在操作各類精密儀器、自動化生產線時，從未非常留意過它。但少了它，設備運轉就像汽車掉了輪子，立馬“趴窩”。想知道這個看似不起眼的小家伙，是如何扛起滾珠絲杠穩定運行的大旗嗎?

　　The composition of the screw support component: On the ball screw, there is a silent "behind the scenes hero" - the screw support component. You may have never paid special attention to it when operating various precision instruments and automated production lines. But without it, the equipment runs like a car loses its wheels and immediately "collapses". Do you want to know how this seemingly inconspicuous little guy carries the banner of stable operation of the ball screw?

　　一、何為絲杠支座組件：與滾珠絲杠配套使用的專用軸承組件。絲杠支座組件是工業自動化設備中用于支撐、固定滾珠絲杠，并保障其穩定運轉的配套零部件組合，是滾珠絲杠傳動系統的核心輔件之一，廣泛應用于機床、機械手、直線模組、自動化生產線等設備。

　　1、 What is a screw support component: a specialized bearing component used in conjunction with ball screws. Screw support components are a set of supporting parts used in industrial automation equipment to support and fix ball screws, and ensure their stable operation. They are one of the core accessories of ball screw transmission systems and are widely used in machine tools, robotic arms, linear modules, automated production lines, and other equipment.

　　二、絲杠支座組件的構成：1、支座殼體組件的基礎承載結構，是整個支座的 “骨架”。材質可選用鑄鐵（高剛性）、鋁合金（輕量化），也可定制不銹鋼（耐腐蝕），用于與設備機架、工作臺等結構固定，同時容納內部軸承等零件。2、精密軸承核心功能部件，決定支座的承載能力和運轉精度。常見類型有角接觸球軸承、深溝球軸承：角接觸球軸承：可承受徑向 + 雙向軸向載荷，適配固定端（FK 系列） 支座；深溝球軸承：僅承受徑向載荷，適配支撐端（FF 系列） 支座。3、軸承定位與鎖緊件包括鎖緊螺母、止動墊圈、軸承端蓋，作用是固定軸承在殼體內的位置，防止軸承在絲杠高速旋轉時發生軸向竄動，保障傳動穩定性。4、密封防塵部件屬于選配部件，包含油封、防塵圈、密封端蓋。主要用于粉塵、潮濕、油污等惡劣工況，避免外界雜質侵入軸承內部，同時防止軸承潤滑脂流失，延長組件使用壽命。

　　2、 The composition of the screw support component: 1. The basic load-bearing structure of the support shell component is the "skeleton" of the entire support. The material can be cast iron (high rigidity), aluminum alloy (lightweight), or customized stainless steel (corrosion-resistant), used for fixing with equipment frames, workbenches, and other structures, while accommodating internal bearings and other parts. 2. The core functional components of precision bearings determine the bearing capacity and operational accuracy of the support. Common types include angular contact ball bearings and deep groove ball bearings. Angular contact ball bearings can withstand radial and bi-directional axial loads and are compatible with fixed end (FK series) supports; Deep groove ball bearings: only capable of bearing radial loads, compatible with support end (FF series) supports. 3. The bearing positioning and locking components include locking nuts, stop washers, and bearing end caps, which are used to fix the position of the bearing inside the housing, prevent axial displacement of the bearing during high-speed rotation of the screw, and ensure transmission stability. 4. Sealed dust-proof components are optional parts, including oil seals, dust-proof rings, and sealed end caps. Mainly used in harsh working conditions such as dust, moisture, oil stains, etc., to prevent external impurities from entering the bearing interior, while preventing the loss of bearing lubricating grease and extending the service life of components.

　　1、適配固定端（FK 系列） 支座的角接觸球軸承：可同時承受徑向載荷和雙向軸向載荷，能抵消絲杠傳動時產生的軸向推力，避免絲杠竄動，保障定位精度，適合高負載、高精度的傳動場景（如數控機床、精密機械手）。2、適配支撐端（FF 系列） 支座的深溝球軸承：僅承受徑向載荷，不限制絲杠的微量軸向伸縮（適配溫度變化導致的絲杠熱脹冷縮），適合對軸向限位要求低的輔助支撐場景。

　　1. Angular contact ball bearings compatible with fixed end (FK series) supports: can withstand both radial and bidirectional axial loads simultaneously, can counteract the axial thrust generated during screw transmission, avoid screw movement, ensure positioning accuracy, and are suitable for high load, high-precision transmission scenarios (such as CNC machine tools and precision robotic arms). 2. Deep groove ball bearings adapted to support end (FF series) supports: only bear radial loads, without restricting the slight axial expansion and contraction of the screw (adapted to thermal expansion and contraction of the screw caused by temperature changes), suitable for auxiliary support scenarios with low axial limit requirements.
