The Bosch Rexroth SUPER LINEAR BUSH KBB-O-12-DD (R067321240) is a high-quality linear bushing designed for applications that require smooth, precise motion and high travel speeds. This particular model is part of the Super LB B series, which is characterized by its open design and lack of self-alignment features, making it suitable for fully supported shafts where other linear guides may not perform optimally due to substructure inaccuracies. The KBB-O-12-DD is engineered with steel bearing plates that have meticulously machined ball guide grooves and optimized ball lead-in chamfers, ensuring exceptionally smooth travel and a long service life. It is designed to transfer lower tipping forces along the axial direction due to the absence of a self-alignment feature. The bushing can accommodate high travel speeds up to a maximum permissible linear speed (vmax), and it's capable of enduring max accelerations (amax) without compromising performance. Equipped with longitudinal seals, this model includes integrated wiper seals that help maintain cleanliness within the bushing by preventing the ingress of contaminants. The ball retainer and outer sleeve are constructed from durable materials such as PA or POM, while the balls themselves are made from rolling bearing steel. Notably, this linear bushing does not require initial lubrication. With a dynamic load capacity (C) that applies primarily in the main loading direction, the KBB-O-12-DD can handle significant loads while maintaining low friction coefficients when lubricated with oil. It operates effectively within an ambient temperature range of -20°C to +80°C. The product also features a static load rating (C0) and specific friction force values under various conditions. Weighing in at just 0.1 kg, this compact linear bushing provides an efficient solution for linear motion requirements across various applications while maintaining Bosch Rexroth's commitment to quality and durability.
