The Bosch Rexroth SUPER LINEAR BUSH (R067121240) is a high-quality linear motion component designed for precision and durability. This model features an open design with a self-aligning capability, which compensates for shaft deflection and misalignment, ensuring smooth travel even on fully supported shafts where other guides may falter due to substructure inaccuracies. It boasts a shaft diameter of 12 mm and is equipped with two seals that provide protection against contaminants while maintaining low friction. The SUPER LINEAR BUSH utilizes steel bearing plates with finely machined ball guide grooves and optimized chamfers, enabling exceptionally smooth motion and an extended service life. The bushing can handle high travel speeds up to 5 m/s and is capable of enduring maximum accelerations without compromise to performance. Its construction includes a ball retainer and outer sleeve made from durable PA or POM materials, while the balls themselves are crafted from high-grade rolling bearing steel. This model has been engineered to function efficiently within a temperature range of -30°C to +80°C. It features an outer diameter (D) of 22 mm, with dynamic load capacities that are applicable primarily in the main direction of loading. The SUPER LINEAR BUSH does not require initial lubrication thanks to its integrated wiper seals which also serve as external seals when necessary. With its low friction coefficient ranging from 0.01 to 0.25 depending on conditions, this linear bushing ensures minimal resistance during operation. The static load rating (C0) stands at 510 N, indicating its robustness under stationary loads. Weighing in at just 0.04 kg, it offers an optimal balance between weight and performance. In summary, the Bosch Rexroth SUPER LINEAR BUSH (R067121240) is a versatile and reliable solution for linear motion applications requiring precision alignment and smooth operation across various environmental conditions and loading scenarios.
