The Bosch Rexroth TORQUE RESIST.BUSH KBDR2-50-WV-600 (R069635080) is a state-of-the-art torqueresistant linear bushing designed for self-supporting, torsionally stiff guides with a single shaft. This product is tailored to facilitate precise linear movements while transferring torque, making it an ideal component for various mechanical and automation applications. The bushing features precision steel shafts with two ball guide grooves, ensuring robust and reliable torque transmission. Constructed with a focus on durability and performance, the KBDR2-50-WV-600 incorporates a ball retainer and outer sleeve made from high-strength PA or POM materials. The bearing plates are crafted from hardened steel, providing excellent resistance to wear and tear. Rolling bearing steel balls ensure smooth operation and longevity. To guarantee zero clearance and optimal functionality, this model comes equipped with a hardened steel adjusting screw and is securely fastened with a steel lock nut. This particular model does not include seals, which allows for customization based on specific application requirements. It has been engineered for easy integration into various systems, boasting simple installation due to its standard length as per the provided table. The dynamic load capacity C and static load capacity C0 are minimal values specified by Bosch Rexroth to account for varying loading directions that cannot always be clearly defined. The KBDR2-50-WV-600 operates efficiently within a permissible ambient temperature range of -30°C to +80°C, accommodating diverse working environments. It can handle maximum accelerations (amax) effectively without compromising performance or safety. With an outer diameter D of 50 mm and a weight of 0.31 kg/m, this linear bushing maintains a balance between size and mass to support dynamic load capacities while enabling high torsional moment load capabilities. Overall, the Bosch Rexroth TORQUE RESIST.BUSH KBDR2-50-WV-600 is designed to meet the demands of high-performance linear motion applications where precision torque transmission is crucial. Its robust construction paired with fine-tuned adjustability makes it an invaluable component in the realm of mechanical engineering and automation systems.

Reduced load capacity with short stroke
In case of short stroke, the service life of the shaft is less than that of the torque-resistant Linear Bushing. The dynamic load ratings C in the tables must therefore be multiplied by the factor fs .
