The Bosch Rexroth ROTARY LINEAR BUSH KBRON-40-DD (R066704000) is a state-of-the-art linear bushing designed to accommodate both linear and rotary motion. This product features a needle bearing for precise guiding under high load ratings, making it ideal for applications that require both high speed and low friction. The ROTARY LINEAR BUSH KBRON-40-DD is particularly suitable for grip and swivel functions, as well as winding applications, where its standard linear bushing closed design ensures reliable operation. Constructed with steel intermediate rings and equipped with retaining rings from SeegerOrbis GmbH, this linear bushing ensures durability and stability in operation. Its dual-seal design enhances the protection against contaminants, further extending the life of the bushing in challenging environments. The dynamic load capacity and static load rating are minimal values due to variable loading orientations and directions; however, they signify the robustness of this component. The outer diameter of the ROTARY LINEAR BUSH KBRON-40-DD is designed to meet specific application requirements while maintaining compatibility with various shaft diameters. It operates efficiently within a permissible ambient temperature range, ensuring consistent performance across different working conditions. Weighing in at just . kg, this product doesn't add significant mass to machinery, contributing to overall equipment efficiency. The ROTARY LINEAR BUSH KBRON-40-DD represents an optimal solution for designers seeking a combined linear and rotary motion rotation component that delivers precision, durability, and reliability in their mechanical systems.

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.
