The Bosch Rexroth TORQUE RESIST.BUSH KBDRC2-25-WV-500 (R072032580) is a state-of-the-art torqueresistant linear bushing designed for self-supporting, torsionally stiff guides with a single shaft. This product features a precision steel shaft with machined ball guide grooves and is configured without seals. The inclusion of hardened steel bearing plates, balls made from rolling bearing steel, and a hardened steel adjusting screw ensures high durability and reliability. The lock nut is crafted from steel, while the ball retainer and outer sleeve are constructed from either PA or POM materials. This linear bushing is part of the compact series within the product group ID Size N. It boasts a dynamic load capacity (C) that represents minimal values due to the variable nature of loading directions. The static load rating (C0) and dynamic torsional moment load capacity (Mt) reflect its robustness in various applications. With an outer diameter (D), this model can operate within an ambient temperature range of -30°C to +80°C, accommodating different environmental conditions. The maximum permissible linear speed (vmax) and acceleration (amax) ensure smooth motion control in fast-paced applications. The closed format of this linear bushing contributes to its streamlined design, making it suitable for compact spaces where efficiency and precision are paramount. Weighing in at 0.3 kg/m, the TORQUE RESIST.BUSH KBDRC2-25-WV-500 provides an optimal balance between weight and performance capabilities. Its design facilitates ease of use for selfsupporting guides that require precise motion control with zero clearance adjustment capabilities via the included adjusting screw. This Bosch Rexroth component is ideal for use in various applications where high torsional resistance is necessary along with reliable linear motion guidance.

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 .
