The Bosch Rexroth TORQUE RESIST.BUSH KBDR2-25-WV-2000 (R069632588) is a high-quality, torque-resistant linear bushing designed for self-supporting, torsionally stiff guides with only one shaft. This model features a precision steel shaft with two ball guide grooves that effectively transfer torque. The ball retainer and outer sleeve are constructed from durable materials such as PA or POM, ensuring longevity and consistent performance. The KBDR2-25-WV-2000 is equipped with hardened steel bearing plates and balls made of rolling bearing steel, which provide smooth motion and high load capacities. The bushing comes with an adjusting screw that is pre-set to zero clearance, allowing for precise adjustments according to customer specifications. Additionally, it incorporates a robust steel lock nut for secure mounting. This model boasts impressive specifications, including a dynamic load capacity C that ensures minimal values due to variable loading directions cannot always be clearly defined. It can operate within a permissible ambient temperature range of -20°C to +80°C, accommodating various working environments. The outer diameter D of the bushing allows for compatibility with different setups while maintaining maximum permissible linear speeds and accelerations. With a weight of 0.5 kg/m, the KBDR2-25-WV-2000 offers an optimal balance between strength and mass, making it suitable for applications requiring precise linear motion under torsional loads. Its closed format ensures protection from external contaminants and enhances the overall system reliability. The dynamic torsional moment load capacity Mt highlights the bushing's ability to handle twisting forces during operation. As part of Bosch Rexroth's Torque Series Productgroup ID Size N, this linear bushing represents a reliable solution for various mechanical applications where controlled linear movement combined with torque resistance is essential.

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 .
