The Bosch Rexroth ROTARY LINEAR BUSH KBROR-20-DD (R066322000) is a sophisticated motion control component designed for applications requiring both linear and rotary motion. This product integrates a deep groove ball bearing with a linear bushing to deliver precise guidance under high load ratings, making it suitable for grip, swivel, and winding functions. The ROTARY LINEAR BUSH KBROR-20-DD is engineered for high-speed operations with minimal friction and can handle dynamic loads with its robust design. This linear bushing is available for various shaft diameters ranging from small to large sizes, ensuring versatility across different applications. It comes equipped with two seals that provide maintenance-free operation and protection against contaminants. The sealed shields are segmental for shaft diameters up to 50 mm, while the steel sleeve caters to shafts up to 80 mm. For larger shafts up to 125 mm, external seals are provided. In addition to its primary function, the ROTARY LINEAR BUSH KBROR-20-DD features an integrated wiper seal system for enhanced durability and performance in environments where cleanliness is paramount. The series offers combined linear and rotary motion capabilities, making it an ideal choice for complex movements within machinery. The outer diameter of the component is precisely manufactured to ensure compatibility with corresponding equipment, while the permissible ambient temperature range extends from -30°C to +80°C. This wide temperature tolerance allows the bushing to operate effectively in diverse working conditions. The dynamic load capacity of this Bosch Rexroth product is indicative of its ability to withstand operational stresses over time, while the static load rating confirms its stability under constant loads. Overall, the ROTARY LINEAR BUSH KBROR-20-DD represents a reliable and efficient solution for advanced motion control requirements in various linear applications with additional rotary motion needs.
