PRD-B040ESIB-32 by Kollmorgen

The Kollmorgen PRD-B040ESIB-32 is a high-performance Precision Ball Screw designed for demanding industrial automation applications within the CD Servostar CD Drives series. This component features a shaft diameter of 40 mm and a 32 mm lead, providing substantial linear travel per revolution for rapid actuation. Crafted from alloy steel (hardened and ground), it delivers superior rigidity under load and long-term dimensional stability. The unit adheres to the C5 accuracy grade, ensuring positional deviations remain under 0.005 mm per 300 mm. Equipped with a light preload, the design minimizes axial play without introducing excessive friction, making it ideal for precision positioning.

Performance characteristics are optimized through a specialized ESI (Internal Circulation) ball nut that ensures continuous return of rolling elements, reducing wear and extending service life. The flange-type nut mounting provides rigid support and prevents misalignment under transverse forces, while customizable end machining options allow seamless integration into a variety of machine tool designs. With a maximum stroke typically up to 3000 mm and configurable shaft length to suit application requirements, this ball screw accommodates both short-travel and long-travel assemblies. Mechanical efficiency approaches 90 %, significantly lowering the required input torque and reducing energy consumption. Critical load capacities are specified via dynamic load rating and static load rating references in the manufacturer catalogue, enabling precise load selection and safety margin calculations.

Reliability is further enhanced by robust material selection and precision manufacturing, delivering consistent performance in industrial environments. Integration into servo drive systems is straightforward, enabling direct coupling to motors for streamlined mechanical assemblies. Typical repeatability of ±0.001 in supports high-definition positioning control in applications such as pick-and-place modules, CNC machinery, and automated inspection stations. Configurable sizing and customizable end treatments make the PRD-B040ESIB-32 exceptionally versatile across automation platforms. Backed by Kollmorgen’s quality standards, this ball screw balances ease of installation with the precision and durability required for advanced motion control systems.
