The Bosch Rexroth ROTARY LINEAR BUSH KBRON-30-DD (R066703000) is a sophisticated component designed for advanced linear motion systems requiring both linear and rotary motion capabilities. This rotary motion linear bushing integrates a needle bearing, which allows for precise guiding under high load ratings while maintaining high speed and low friction performance. The shaft diameter 'd' is tailored to fit specific applications, and the inclusion of two seals ensures durability and longevity in various operating conditions. The ROTARY LINEAR BUSH KBRON-30-DD is particularly suitable for grip and swivel functions, as well as winding applications where combined linear and rotary movements are essential. Its construction features standard linear bushing closed with steel intermediate rings that enhance stability and strength. Additionally, retaining rings such as the SeegerOrbis GmbH Series provide secure locking mechanisms to maintain the integrity of the assembly under dynamic conditions. This product boasts an impressive dynamic load capacity, with minimal values indicated due to varying orientations and directions of loading in different applications. The static load rating also reflects its ability to withstand substantial loads without compromising functionality. The permissible ambient temperature range for this bushing ensures reliable operation across different environments. Designed with a focus on precision and efficiency, the ROTARY LINEAR BUSH KBRON-30-DD is part of a product group that specializes in combined linear and rotary motion rotation. Its format N with needle bearing underscores its ability to cater to complex motion requirements while maintaining a compact form factor. This bushing's weight has been optimized to contribute positively to the overall system without sacrificing performance, making it an excellent choice for sophisticated linear motion systems.

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.
