8I84T400400.010-1
The B & R Automation 8I84T400400.010-1 precision component is a specialized member of the 8I7 ACOPOS Inverters series, designed for high-performance industrial automation assemblies. Constructed from durable Tool Steel, this part spans a total Length of 400 mm with a nominal Diameter of 4.00 mm and maintains a stringent Tolerance of +0/-0.010 mm for precise fit-ups. Weighing approx. 0.4 kg, it strikes an optimal balance between mechanical strength and overall system mass. The component’s Polished Surface Finish reduces friction and enhances fluid lubrication retention in dynamic environments. To support accurate integration, both ends are Ground and chamfered, ensuring smooth edge transitions and simplified mounting. The robust design complements a Medium Corrosion Resistance rating, making it suitable for a range of operating environments.
Performance characteristics of the 8I84T400400.010-1 emphasize exceptional geometric accuracy and endurance under cyclic loads. A Straightness of 0.01 mm over full length and Concentricity of 0.005 mm guarantee minimal runout and low vibration in high-velocity linear and rotary motion systems. The high surface hardness (HRC 60-62) provides superior wear resistance against abrasive contact, while the polished finish prolongs service life by minimizing surface fatigue. Operational stability is sustained across a broad Temperature Range of -40°C to +180°C, ensuring dimensional integrity in both extreme cold storage and elevated thermal conditions. The combination of precise mechanical tolerances and surface treatments supports smooth actuation, reduced maintenance intervals, and consistent performance in continuous-duty applications.
Engineered for reliability and seamless integration, this component benefits from the inherent strength of tool steel construction and robust corrosion-resistant properties. The precise end finishing and tight tolerances facilitate direct installation into guideways, bearing systems, and rotary assemblies without requiring additional machining. Its mechanical resilience and fine surface polish make it ideally suited for actuators, precision shafts, support rods, and motion guides within machine tools, robotics, and automated production lines. The 8I84T400400.010-1 excels in high-stress applications where durability, alignment accuracy, and minimal downtime are critical. When deployed within B & R’s ACOPOS inverter ecosystem, it contributes to optimized machine responsiveness and long-term operational stability.
