The Bosch Rexroth RADIAL LINEAR BUSH KBR-40-VD (R067824045) is a high-precision, fully sealed radial linear bushing designed to move very heavy loads with exceptional smoothness and accuracy. This robust component features radial ball redirection, which allows for multiple rows of balls, leading to extremely high load ratings and making it an ideal choice for applications that require heavy-duty guidance with degrees of freedom in the circumferential direction. Its design combats warping that can occur in other linear guides due to imprecise substructures. The KBR-40-VD boasts very high rigidity and extra smooth running characteristics. It is relubricatable, enhancing its longevity and performance in various operating conditions. The bushing is constructed with a hardened and machined steel sleeve, a ball retainer made of reinforced PA, and balls crafted from rolling bearing steel – all contributing to its durability and reliability. This model comes equipped with two retaining rings and has the option for separate wiper seals if needed. It supports a dynamic load capacity C that applies for the main direction of loading, ensuring consistent operation under significant weight. The outer diameter D is meticulously crafted to accommodate the required shaft dimensions, while the shaft radial clearance hbore K and hbore JS are designed to reduce service life due to high preload. With a friction coefficient as low as 0.01 under certain conditions, the RADIAL LINEAR BUSH KBR-40-VD ensures minimal resistance during operation. It can withstand a maximum acceleration amax and operates efficiently within a permissible ambient temperature range of -30°C to +80°C. Overall, this linear guide type bushing is suited for applications demanding high load capacity and precision movement without compromising on smoothness or rigidity. Its design parameters make it adaptable for various industrial requirements where precision linear movement is critical.
