The Bosch Rexroth ROTARY LINEAR BUSH KBRON-8 (R066500800) is a state-of-the-art rotary motion linear bushing designed for high precision and durability in linear applications that also require additional rotary motion. This product integrates a needle bearing for precise guiding even under high load ratings, ensuring both high speed and low friction operation. Its innovative design makes it particularly suitable for grip and swivel functions, as well as for winding applications. Constructed with standard closed linear bushing and steel intermediate rings, the KBRON-8 ensures reliable performance and longevity. The inclusion of retaining rings, specifically the retaining ring SB from SeegerOrbis GmbH, further enhances the integrity of the assembly. This product is part of the Combined linear and rotary motion rotation series within Bosch Rexroth's product offerings. The ROTARY LINEAR BUSH KBRON-8 operates efficiently within a wide range of temperatures, from a minimum to maximum permissible ambient temperature, maintaining its dynamic functionality across diverse environments. It boasts an impressive static load rating C and dynamic load capacity C, although it's important to note that these capacities are minimal values due to the potential variability in orientation and direction of loading. Designed without seals for unencumbered movement, this linear bushing with needle bearing is ideal for scenarios where both linear guidance and rotational movement are required. With its outer diameter D tailored to fit seamlessly into corresponding assemblies and its lightweight design, this component offers an optimal solution for engineers looking to enhance their systems with a reliable bushing that can handle combined motions effectively.

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.
