The Bosch Rexroth ROTARY LINEAR BUSH KBRON-20 (R066502000) is a state-of-the-art linear bushing designed to facilitate precise guiding under high load ratings, combining both linear and rotary motion capabilities. This particular model is notable for its integration of needle bearings, which contribute to its high-speed performance and low friction characteristics, making it an ideal choice for applications that require both linear movement and additional rotary motion such as grip and swivel functions or winding applications. The ROTARY LINEAR BUSH KBRON-20 is engineered without a seal, featuring a standard closed linear bushing that ensures durability and reliability in operation. The steel intermediate rings enhance the structural integrity of the bushing, while the retaining rings provided by SeegerOrbis GmbH secure the components in place. This product is part of Bosch Rexroth's series that combines linear and rotary motion, reflecting their commitment to versatile and efficient motion solutions. With a dynamic load capacity that represents minimal values due to variable loading orientations and directions, this linear bushing can withstand significant forces. It operates effectively within a permissible ambient temperature range, ensuring consistent performance across different working conditions. The outer diameter of the bushing is designed to meet specific application requirements while maintaining compatibility with various shaft diameters. Additionally, the ROTARY LINEAR BUSH KBRON-20's static load rating underscores its ability to handle static forces without compromising functionality. Its format with needle bearing enhances its dynamic load capacity, further contributing to its overall efficiency. Weighing in at just . , this product exemplifies Bosch Rexroth's dedication to producing lightweight yet robust components for industrial use. In summary, the ROTARY LINEAR BUSH KBRON-20 (R066502000) from Bosch Rexroth is a versatile component suitable for high-speed, low-friction linear applications requiring additional rotary movements. Its robust design and dynamic load handling make it an exceptional choice for demanding mechanical tasks.

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.
