The Bosch Rexroth ROTARY LINEAR BUSH KBROR-12-DD (R066321200) is a state-of-the-art rotary motion linear bushing that incorporates a deep groove ball bearing design, optimized for high load ratings and precise guiding. This component is engineered to facilitate both linear and rotary motions, making it ideal for grip, swivel, and winding applications where high speed and low friction are essential. The KBROR-12-DD is designed with integrated wiper seals for shaft diameters of 3, 4, 5, 6, and 8mm to ensure maintenance-free operation and longevity of the bushing. Additionally, the product features segmental linear bushings suitable for shaft diameters ranging from 12 to 50mm and a steel sleeve for shafts from 12 to 30mm. External seals are provided for shaft diameters from 3 to 50mm to protect against contaminants. The pressed-on deep groove ball bearing is standard across linear bushing models designed for shaft diameters of 3, 4, 5, 6, and 8mm. The ROTARY LINEAR BUSH KBROR-12-DD boasts an impressive dynamic load capacity (C), although it's noted that these capacities are minimal values due to the variability in orientation and direction of loading. The static load rating (C0) similarly indicates minimal values under static conditions. This product operates efficiently within a permissible ambient temperature range of -20°C to +80°C. With an outer diameter (D) tailored for compatibility with various applications and a weight of just .45kg, this linear guide type offers exceptional performance in a compact form factor. In summary, the Bosch Rexroth ROTARY LINEAR BUSH KBROR-12-DD (R066321200) represents a versatile solution combining high-quality materials with advanced engineering to provide reliable linear and rotary motion in demanding industrial applications.
