The Bosch Rexroth ROTARY LINEAR BUSH KBRORD-8-DD (R066420800) is an advanced mechanical component designed for precise guiding under high load ratings. It is specifically engineered to provide both linear and rotary motion, making it suitable for applications that require grip, swivel functions, or winding processes. This product features a deep groove ball bearing with shields and incorporates two seals to ensure maintenance-free operation and longevity. The ROTARY LINEAR BUSH KBRORD-8-DD is prelubricated and comes with pressed-on deep groove ball bearing segmental linear bushings, accommodating shaft diameters from 3 to 50 mm. It also includes a steel sleeve for shaft diameters of 12 to 50 mm. For enhanced protection against contaminants, external seals are standard for shaft diameters of 12 to 50 mm, while integrated wiper seals are included for shafts measuring 5, 8, 10, 12, and 16 mm. This product boasts a dynamic load capacity (C) that ensures high-speed performance with minimal friction. Its design caters to the need for reliable linear guidance in various industrial applications while providing the additional capability of rotary motion. The outer diameter (D) of the bushing is optimized for compatibility with corresponding machinery components. The ROTARY LINEAR BUSH KBRORD-8-DD has a permissible ambient temperature range from -30°C to +80°C, allowing it to operate effectively in diverse environmental conditions. With its robust construction and versatile design, this Bosch Rexroth linear bushing stands out as a critical component in the realm of motion control solutions.
