The Bosch Rexroth COMPACT LIN. BUSH. KBC-12-DD (R065821240) is a high-performance compact linear bushing designed for smooth and precise linear motion applications. This product features a shaft diameter of d, ensuring compatibility with standard-sized components. It comes equipped with two seals to protect against contaminants and is characterized by its standard radial clearance and non-lubricated design, making it suitable for various environments where minimal maintenance is desired. The COMPACT LIN. BUSH. KBC-12-DD boasts small outer dimensions coupled with a highly compact construction, allowing for integration into space-constrained applications without sacrificing performance. Its dynamic load rating is enhanced by hardened segmental load-bearing plates that provide ball conformity in the running track, facilitating high travel speeds and a long service life. Notably, the linear bushing offers integrated wiper seals to prevent dirt ingress, which can be crucial in maintaining smooth operation over time. The product's pockets serve as lubricant reservoirs that can extend lubrication intervals or even allow for lifetime lubrication, depending on the application's demands. Installation of this linear bushing is straightforward due to its simple press-fit mounting; no additional retention mechanisms are required. The integrated metal retainer is approximately 0.5mm larger than the outer diameter of the shaft diameters ranging from 3 to 50 mm, ensuring a secure fit within the housing bore. The COMPACT LIN. BUSH. KBC-12-DD supports a maximum dynamic load capacity (Cmax), operates efficiently within an ambient temperature range of -30°C to +80°C, and can handle maximum accelerations (amax). Its friction coefficient ranges from 0.01 to 0.25 depending on conditions such as load and lubrication status. With a weight of only 0.02 kg and normal radial clearance without grease, this Bosch Rexroth compact linear bushing represents an efficient solution for general requirements in linear motion systems—combining durability with ease of use in various applications requiring precise guidance and movement.
