　　丝杠支座组件的构成：在滚珠丝杠上，藏着一个默默发力的“幕后英雄"- 丝杠支座组件。你可能在操作各类精密仪器、自动化生产线时，从未特别留意过它。但少了它，设备运转就像汽车掉了轮子，立马“趴窝”。想知道这个看似不起眼的小家伙，是如何扛起滚珠丝杠稳定运行的大旗吗?

　　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、何为丝杠支座组件：与滚珠丝杠配套使用的专用轴承组件。丝杠支座组件是工业自动化设备中用于支撑、固定滚珠丝杠，并保障其稳定运转的配套零部件组合，是滚珠丝杠传动系统的核心辅件之一，广泛应用于机床、机械手、直线模组、自动化生产线等设备。

　　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、丝杠支座组件的构成：1、支座壳体组件的基础承载结构，是整个支座的 “骨架”。材质可选用铸铁（高刚性）、铝合金（轻量化），也可定制不锈钢（耐腐蚀），用于与设备机架、工作台等结构固定，同时容纳内部轴承等零件。2、精密轴承核心功能部件，决定支座的承载能力和运转精度。常见类型有角接触球轴承、深沟球轴承：角接触球轴承：可承受径向 + 双向轴向载荷，适配固定端（FK 系列） 支座；深沟球轴承：仅承受径向载荷，适配支撑端（FF 系列） 支座。3、轴承定位与锁紧件包括锁紧螺母、止动垫圈、轴承端盖，作用是固定轴承在壳体内的位置，防止轴承在丝杠高速旋转时发生轴向窜动，保障传动稳定性。4、密封防尘部件属于选配部件，包含油封、防尘圈、密封端盖。主要用于粉尘、潮湿、油污等恶劣工况，避免外界杂质侵入轴承内部，同时防止轴承润滑脂流失，延长组件使用寿命。

　　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、适配固定端（FK 系列） 支座的角接触球轴承：可同时承受径向载荷和双向轴向载荷，能抵消丝杠传动时产生的轴向推力，避免丝杠窜动，保障定位精度，适合高负载、高精度的传动场景（如数控机床、精密机械手）。2、适配支撑端（FF 系列） 支座的深沟球轴承：仅承受径向载荷，不限制丝杠的微量轴向伸缩（适配温度变化导致的丝杠热胀冷缩），适合对轴向限位要求低的辅助支撑场景。

　　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.
