The article develops the design of the mechanism taking into account the requirements for operation in conditions of extreme pressures, temperatures, lack of energy consumption and maintenance. The magnetic system is a composition of permanent magnets with alternating polarity made of rare earth metal alloys with cobalt SmCo5. Based on the fact that the magnetization of magnets made of rare earth metal alloys can be assumed to be homogeneous, anisotropic and independent of the magnitude of the demagnetizing field, the Ampere hypothesis was adopted to calculate the magnetostatic forces of the mechanism. The theoretical calculation of the tangential force of the interaction of magnets made it possible to calculate the optimal dimensions of the magnetic system and obtain the greatest pulling force with the minimum overall dimensions of the mechanism. Experimental analysis of the simulation results of tangential magnetostatic forces of the mechanism with magnets made of SmCo5 alloy showed that the discrepancy between the calculated and experimental values of the force did not exceed 12 %.
