The Bosch Rexroth ROTARY LINEAR BUSH KBRON-20-DD (R066702000) is a high-precision component designed for advanced linear motion systems that require an additional rotary motion capability. This product is a rotary motion linear bushing that incorporates needle bearings, offering precise guiding under high load ratings while maintaining low friction for efficient operation. It is particularly suitable for applications with grip and swivel functions, as well as for winding applications where both linear and rotational movements are necessary. With a shaft diameter of 20 mm, the ROTARY LINEAR BUSH KBRON-20-DD ensures stability and accuracy in operation. It comes equipped with two seals to provide protection against contaminants, thereby extending the service life of the bushing. The use of steel intermediate rings and retaining rings, such as those from SeegerOrbis GmbH Series, further enhances the durability and reliability of this bushing. The dynamic load capacity C indicates minimal values due to the variable orientation and direction of loading in different applications. Similarly, the static load rating C reflects minimal values to account for these varying conditions. The outer diameter D is designed to fit standard housing sizes, while the permissible ambient temperature range allows for operation in various environmental conditions without compromising performance. This product falls under the product group ID for combined linear and rotary motion rotation and represents an optimal solution for sophisticated engineering applications that demand both types of movement. Its design facilitates high speed operations with minimal frictional resistance, making it an excellent choice for dynamic systems. The ROTARY LINEAR BUSH KBRON-20-DD's features make it a versatile component suitable for a wide array of industrial applications where precision and robustness are paramount.

Life expectancy calculation

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.
