The Bosch Rexroth ROTARY LINEAR BUSH KBRORD-20-DD (R066422000) is a high-performance component designed for precision linear motion with additional rotary motion capabilities. This linear bushing integrates a deep groove ball bearing with shields, ensuring high load ratings and smooth operation at high speeds with low friction. It is specifically engineered to cater to applications that require precise guiding under heavy loads, such as grip and swivel functions or winding tasks. The ROTARY LINEAR BUSH KBRORD-20-DD supports shaft diameters ranging from 3 to 50 mm and comes with two seals for enhanced performance and longevity. It is pre-lubricated and maintenance-free due to the sealed shields, which also protect against contaminants. The pressed-on deep groove ball bearing design allows for segmental linear bushings suitable for various shaft diameters, while the steel sleeve covers larger shaft diameters from 12 to 50 mm. This product also includes external seals standard on linear bushings for shaft diameters from 3 to 50 mm, as well as integrated wiper seals on select sizes (12, 16, 20, 25, and 30 mm) to preserve internal components' integrity. The dynamic load capacity C is specified by Bosch Rexroth as minimal values due to the varying orientation and direction of loading in different applications. The ROTARY LINEAR BUSH KBRORD-20-DD can operate within a permissible ambient temperature range of -30°C to +80°C. Its outer diameter D measures at an optimal size for compatibility with various setups. With its robust construction and meticulous design, this linear guide type ensures reliability in diverse operational contexts while maintaining its efficiency over time. The weight of this component is noted at .5 kg, indicating a solid yet manageable piece of equipment suitable for a wide array of industrial applications.
