Abstract Flux motion in anisotropic type-II superconductors near Hc 2 is studied in the framework of the time-dependent Ginzburg-Landau (TDGL) theory for the case that the average flux densityB is oriented in an arbitrary direction relative to the principal axes of the sample. The linearized TDGL equation for a uniformly translating order parameter is solved and expressions for all elements of the flux-flow resistivity tensor ϱij (including the off-diagonal Hall elements) are obtained. The diagonal elements ϱii show the angular scaling property that ϱii(B) = ϱii(B/Hc 2(θ, ø)), whereas the Hall elements ϱij (i ≠ j) have additional angular dependences that are not contained in Hc2. For the case that the normal state Hall elements ϱ ij (n) ∝B k with i ≠ j ≠ k, the ratios ϱij/ϱ ij (n) are functions of B/Hc2 (θ, φ) only.
