The Bosch Rexroth SUPER LINEAR BUSH KBB-O-30-DD (R067323040) is a high-performance linear bushing designed for applications requiring smooth and precise linear motion. This model features steel bearing plates with precisely machined ball guide grooves and optimized ball lead-in chamfers, ensuring remarkably smooth travel and an extended service life. The KBB-O-30-DD does not have a self-alignment feature, making it suitable for transferring lower tipping forces along the axial direction. This open linear bushing is intended for use on fully supported shafts, especially in scenarios where other linear guides may warp due to imprecise substructures. It boasts a high travel speed capability and comes equipped with longitudinal seals to protect against contaminants. The integrated wiper seals can be either external or omitted based on the application's requirements. The ball retainer and outer sleeve of the KBB-O-30-DD are constructed from durable PA or POM materials, while the balls themselves are made from rolling bearing steel. This bushing does not require initial lubrication, which simplifies installation and maintenance. It has multiple rows of balls that contribute to its dynamic load capacity and has been tested to achieve total travel ranging from 10^4 m to 10^5 m without failure. With a static load rating C0 and dynamic load capacity C, this linear bushing is capable of handling significant loads in its main direction of loading. It operates effectively within an ambient temperature range of -20°C to +80°C. The KBB-O-30-DD is also characterized by its low friction coefficient, which varies depending on the load but remains within specified values even under low loads. Weighing in at 0.3 kg, this Bosch Rexroth linear bushing offers a reliable solution for designers and engineers seeking a cost-effective yet high-quality component for their linear motion systems.
