The paper considers a design of a radial hydrostatic compensator for deformations in a machine-tool technological system. The paper also presents its mathematical model and a method for computing its static properties. We show that this design is capable of ensuring a stable negative compliance value in the low and moderate load ranges. We established that the form the characteristic curves take is largely dependent on the tuning coefficient for the friction loss in the input throttle, which has an optimum value in terms of load property stability. We provide an example of computing compensator parameters and determine that it is capable of performing its functions in a machine tool with real-world characteristics
