The Bosch Rexroth RADIAL LINEAR BUSH KBR-80-VD (R067828045) is a high-precision, fully sealed radial linear bushing designed for the movement of very heavy loads with exceptional smoothness and rigidity. This bushing features a radial ball redirection system that accommodates numerous rows of balls, resulting in extremely high load ratings. Its heavy-duty construction allows for degrees of freedom in the circumferential direction, making it ideal for applications vulnerable to warping caused by imprecise substructures. The KBR-80-VD is equipped with a hardened and machined steel sleeve and a ball retainer constructed from reinforced polyamide (PA), ensuring durability and longevity. The balls are made from rolling bearing steel, which contributes to the bushing's high performance. With two retaining rings included, this linear guide maintains its structural integrity under significant loads. This model offers extra smooth running due to its design and can be utilized either fully sealed or without wiper seals, according to specific application requirements. Separate wiper seals are available as an option. Additionally, the bushing is relubricatable, which extends its service life and maintains efficiency over time. The KBR-80-VD has been engineered with specific attention to friction force and coefficient, ensuring minimal resistance during operation. It can withstand a wide range of ambient temperatures from -30°C up to 80°C while maintaining a max acceleration of amax and maximum permissible linear speed vmax. With an outer diameter D specification and various shaft radial clearances options such as hbore K and hbore JS, this linear bushing can be adapted to fit different shaft configurations. The static load rating C0 and dynamic load capacity C indicate the bush's ability to handle static and dynamic stresses respectively. Overall, the Bosch Rexroth RADIAL LINEAR BUSH KBR-80-VD is a robust solution for industries requiring precise linear motion under substantial load conditions while maintaining high rigidity and smooth operation.
