The Bosch Rexroth ROTARY LINEAR BUSH KBRON-25-DD (R066702500) is a state-of-the-art rotary motion linear bushing designed for high-precision applications requiring both linear and rotary motion. It integrates a needle bearing, which ensures precise guiding under high load ratings while maintaining high speed and low friction performance. This makes it suitable for grip and swivel functions, as well as winding applications where accurate and smooth movement is critical. The ROTARY LINEAR BUSH KBRON-25-DD is characterized by its robust construction, featuring steel intermediate rings and retaining rings from SeegerOrbis GmbH that contribute to the unit's durability and reliability. The use of two seals in its design ensures that the internal mechanisms are protected from contaminants, thereby extending the service life of the bushing. This product boasts an impressive dynamic load capacity, although it's important to note that the indicated minimal values account for varying orientations and loading directions which may not always be clearly defined. The same consideration applies to its static load capacity. The permissible ambient temperature range for optimal operation is specified, ensuring that the bushing performs consistently within those thermal conditions. Designed with a closed standard linear bushing format, this model maintains compatibility with various linear guides while offering the additional functionality of rotary motion. The outer diameter and shaft diameter are engineered to meet stringent requirements for seamless integration into existing systems or new installations. In summary, the ROTARY LINEAR BUSH KBRON-25-DD by Bosch Rexroth is a versatile component ideal for sophisticated linear applications that also require rotational capabilities, such as automated production lines or specialized machinery where precision and reliability are paramount. Its design reflects a commitment to quality and performance in demanding industrial environments.

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.

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.
