The Bosch Rexroth TORQUE RESIST.BUSH KBDR4-FM-8DD (R072620800) is a high-precision linear bushing designed for applications requiring self-supporting, torsionally stiff guides with a single shaft. This miniature flanged version is specifically engineered to transfer torque efficiently, thanks to its four ball guide grooves. The bushing is suitable for use with matching shaft profiles that have machined ball guide grooves, tailored to customer specifications. Constructed with a hardened and ground outer sleeve, the KBDR4-FM-8DD ensures durability and consistent performance. It incorporates a POM ball retainer and balls made of rolling bearing steel, which contribute to its smooth operation and reliability. The integrated wiper seals offer protection against contamination, extending the life of the bushing. This particular model is relubricatable, allowing for easy maintenance and prolonged service life under varying operating conditions. It has been designed to withstand a wide range of ambient temperatures from -20°C to +80°C, accommodating different environmental requirements. Additionally, the KBDR4-FM-8DD boasts impressive load capacities—both dynamic and static—with minimal values provided due to potential variations in loading directions. The static torsional moment load capacity (Mt) and dynamic torsional moment load capacity (Mt) underline the bushing's capability to handle significant loads during operation. Furthermore, it can achieve a maximum permissible linear speed (vmax), ensuring efficient motion control in fast-paced applications. With its lightweight design at just 0.08 kg, this linear bushing offers an optimal balance between strength and ease of integration into various systems. The Bosch Rexroth TORQUE RESIST.BUSH KBDR4-FM-8DD represents an advanced solution for precise linear motion requirements in compact spaces where torque resistance is critical.
