The Bosch Rexroth ROTARY LINEAR BUSH KBRON-80-DD (R066708000) is a state-of-the-art rotary motion linear bushing designed to provide precise guiding at high load ratings. It is specifically engineered for linear applications that require additional rotary motion, making it an ideal component for grip and swivel functions as well as winding applications. The KBRON-80-DD features needle bearings for high speed and low friction operation, ensuring smooth and efficient performance. With a shaft diameter of 80 mm and equipped with two seals, this standard linear bushing closed type ensures durability and longevity in various operating conditions. The steel intermediate rings enhance the structural integrity of the bushing, while the retaining rings from SeegerOrbis GmbH offer secure locking mechanisms to maintain consistent performance. This product is capable of handling dynamic load capacities with minimal values due to its robust construction, although the exact orientation and direction of loading may influence these values. The static load rating also reflects minimal values for similar reasons. The KBRON-80-DD operates effectively within a wide range of permissible ambient temperatures, ensuring reliability across diverse environments. The outer diameter of the bushing allows for seamless integration into existing systems without requiring significant modifications. Additionally, its weight has been optimized to contribute to overall system efficiency without compromising on strength or functionality. Overall, the Bosch Rexroth ROTARY LINEAR BUSH KBRON-80-DD is a versatile and reliable component suitable for demanding applications that necessitate both linear movement and rotational capability. Its design reflects Bosch Rexroth's commitment to precision engineering and quality manufacturing in motion control technologies.

Recommended installation tolerances
Shaft: dh6 Housing bore DK6 or DK7 Another tolerance zone can be chosen in special instances. See recommended installation for axial retention of the needle bearing in the housing. Installing the needle bearing in the housing without additional axial securing is sufficient for numerous applications. Needle bearing with backlash on standard Linear Bushing.General mounting instructions
Initial lubrication
Linear bushings do not come with initial lubrication. Grease the Linear Bushings before use. Service life data is based on initial lubrication and relubricated Linear Bushings.
