The Bosch Rexroth COMPACT LIN. BUSH. KBC-40-DD-NR (R065824030) is a high-performance compact linear bushing designed for smooth and precise linear motion in various applications. This product features a corrosion-resistant construction, making it suitable for use in challenging environments such as those found in the medical, chemistry, and food industries. The bushing is equipped with two seals to protect against contaminants and is not pre-lubricated, allowing for flexibility in maintenance protocols. With a shaft diameter of 40mm, this model offers small outer dimensions and a highly compact design that accommodates space-constrained applications without sacrificing dynamic load capacity or service life. The bushing's load-bearing plates are hardened and feature ball conformity in the running track to ensure high dynamic load ratings and durability. Moreover, the integrated wiper seals enhance protection against dirt ingress, contributing to the linear bushing's reliability. Designed with simplicity in mind, the KBC-40-DD-NR can be easily mounted by pressing onto the shaft—no additional retention is required. It has many pockets that act as lubricant reservoirs for extended lubrication intervals or even lifetime lubrication, depending on usage conditions. These pockets also serve to collect any dirt that may enter the system to prevent jamming. The product supports high travel speeds up to m/s while maintaining low friction coefficients between 0.01 and 0.25 under various loads with a maximum dynamic load capacity of Cmax and a minimum dynamic load capacity of Cmin based on total travel distances of 100 km or more. It can operate within an ambient temperature range from -30°C to +80°C. The COMPACT LIN. BUSH. KBC-40-DD-NR weighs approximately kg and provides normal radial clearance without grease applied from factory settings—a testament to its design for low-maintenance operation while ensuring secure fitment within housing bores due to integrated metal holding rings that are slightly larger than the outer diameter of compatible shaft diameters ranging from mm to mm.
