en.Wedoany.com Reported - Bosch Rexroth has introduced custom ball screw and planetary roller screw assemblies tailored for industrial sectors such as automated guided vehicles, medical equipment, and semiconductor manufacturing, meeting specific space, thermal, and safety requirements. This solution combines standard mechanical components with specialized engineering modifications to provide reliable linear motion technology for highly specific industrial applications.
In high-precision machine tool applications, Bosch Rexroth maintains dimensional stability through temperature-controlled screws. These components utilize deep holes and rotating bushings, directly integrated into existing cooling circuits, ensuring process stability and workpiece accuracy by actively managing thermal expansion during continuous operation. For sheet metal forming operations, servo presses use preloaded end bearings to reduce engineering overhead and mechanical assembly time.
In robotics, space constraints dictate compact drive integration. For end-of-arm tools such as robotic welding guns, custom nuts with external teeth are used for pinion drives, enabling direct integration into mechanical systems to accommodate specific motion trajectories and extremely limited installation spaces without external gear components.
Specialized screw drives operating in highly regulated or sensitive environments require unique mechanical modifications. For medical imaging equipment, such as computed tomography (CT) scanners and X-ray tubes, mechanical safety is managed by integrating stop nuts. These auxiliary nuts provide redundant mechanical retention, preventing free fall of components and ensuring patient safety in the event of primary thread failure or emergency situations.
In semiconductor manufacturing, linear motion components must operate under harsh environmental conditions such as high temperatures and deep vacuum. This adaptability is achieved through the use of special structural materials, custom surface coatings, and advanced ball deflection systems designed for high dynamic cycles. Optical manufacturing applications employ matte silver or matte black chrome plating on screw shafts to eliminate stray light reflections that could interfere with sensitive optical measurement sensors.
In intralogistics applications, to facilitate automatic adjustment of fork spacing based on different pallet sizes, the mechanical drive uses a single continuous screw shaft machined with both right-hand and left-hand threads. This dual-thread design enables synchronized, opposing linear motion from a single rotary input motor.
The engineering workflow for these custom modifications is supported by the Linear Motion Technology Selector digital selection platform. This software tool generates precise computer-aided design models and technical documentation based on input parameters, accelerating the selection and design process for modified standard components.
