PRD-B040ESIB-32

The Kollmorgen PRD-B040ESIB-32 precision ball screw from the CD Servostar CD Drives series is engineered to deliver high-speed linear motion with exceptional rigidity and reliability. Featuring a 40 mm shaft diameter and a 32 mm lead, this ball screw provides significant linear travel per revolution, reducing cycle times in demanding industrial automation tasks. The integrated ESI (Internal Circulation) ball nut ensures continuous ball return, minimizing wear and maintaining smooth operation over extended service life. A robust flange-type nut mounting secures the unit against misalignment under transverse loads while allowing direct coupling to servo motors. Crafted by Kollmorgen, this unit balances performance and durability for precision motion control applications.

Detailed specifications reflect the module’s versatility and precision. The Accuracy Grade of C5 guarantees positional deviations below 0.005 mm per 300 mm, while the Ball Nut Type is precisely defined as ESI (Internal Circulation) to promote uniform load distribution and low noise. The Dynamic Load Rating and Static Load Rating are provided in the manufacturer catalogue to guide selection for specific load conditions. Shaft dimensions include a Shaft Diameter of 40 mm and a customizable Shaft Length per application requirements. The Material is hardened and ground Alloy Steel, ensuring dimensional integrity over time. Maximum assembly lengths reach up to a Maximum Stroke of 3000 mm, and End Machining Options allow tailored shaft ends and mounting features. The configuration also incorporates Light Preload to minimize axial play without excessive friction, and a Flange Nut Mounting design to maintain rigid support.

Operational features emphasize efficiency and precision. Mechanical efficiency approaches 90 %, reducing required drive torque and lowering energy consumption across repeated cycles. The ball screw achieves a typical repeatability of ±0.001 in, enabling high-definition positioning control in semiconductor, medical, or packaging machinery. Continuous internal circulation of balls minimizes localized stress, extends bearing life, and maintains consistent friction levels. The combination of high lead and optimized preload delivers swift response to acceleration commands while preserving smooth motion under varying load conditions.

System integration is streamlined through compatibility with standard servo drives and direct coupling to precision motors, eliminating the need for intermediary couplings or elaborate alignment procedures. Customizable shaft lengths and end machining options facilitate integration into bespoke machine designs and retrofit applications. The PRD-B040ESIB-32 is ideally suited for industrial automation, CNC machining centers, semiconductor handling systems, and high-speed pick-and-place equipment. Its robust construction and precise motion characteristics make it an integral component in advanced manufacturing environments where accuracy, reliability, and performance are paramount.
