Technical Data for Rexroth Strut Profiles: Material Properties and Geometric Tolerances, Study notes of Material Engineering

University of LeedsMaterial Engineering

Technical data for rexroth strut profiles, including material properties such as minimum tensile strength, 0.2% proof stress, modulus of elasticity, brinell hardness, and longitudinal expansion coefficients. It also includes information on anodizing process, layer thickness, and layer hardness. Additionally, it outlines geometric tolerances for longitudinal straightness, longitudinal torsional, and profile deflection. Essential for engineers and technicians involved in the design, manufacturing, and application of rexroth strut profiles.
