The Bosch Rexroth RADIAL LINEAR BUSH KBR-50 (R067805000) is an advanced linear motion component designed for high precision and heavy load applications. This radial linear bushing operates without seals, enabling it to handle very heavy loads with ease. Its design includes a radial ball redirection system that allows for multiple rows of balls, resulting in extremely high load ratings and making it suitable for circumstances where other linear guides may fail due to warping from imprecise substructures. The KBR-50 bushing features a hardened and machined steel sleeve, a ball retainer made of reinforced polyamide (PA), and rolling bearing steel balls, all contributing to its very high rigidity and extra smooth running capabilities. It has been designed with the option to be fully sealed or to operate without wiper seals, with separate wiper seals available if needed. The component is also relubricatable, ensuring long-term maintenance possibilities. With a dynamic load capacity C of up to 24.5 kN and static load rating C0 of 38 kN, the KBR-50 is capable of handling significant forces in its main loading direction. It accommodates shaft diameters d ranging from 5 mm up to 50 mm. The product's design includes two retaining rings that contribute to its stability and performance. The friction coefficient for this model is minimized at max. 0.02 when lubricated with oil, which facilitates smoother operation under various conditions. The bushing can endure a maximum acceleration of 50 m/s² and operate within an ambient temperature range from -20°C up to +80°C. Weighing approximately 1 kg, the Bosch Rexroth RADIAL LINEAR BUSH KBR-50 offers a breakaway force specific to its design parameters and achieves maximum permissible linear speed vmax relevant to its size category. With such specifications, it ensures reliable performance in demanding industrial applications requiring precise linear movement under substantial loads.
