The invention belongs to the field of production of an automobile hub bearing unit, and particularly relates to a measurement system and method for spin riveting pressure of a non-drive hub bearing unit. The measurement system comprises an outer ring, an outer-column steel ball, an inner-column steel ball, a flange plate, an outer retainer, an inner retainer, a bolt and strain gauges. The system is reasonable in structural design, the measurement method is simple and convenient, a value of axial pressure remaining on the hub bearing unit after the spin riveting process of the hub bearing unit is accurately measured, an axial pre-tightening effect in a bearing loading state is determined, the problem of breakage of a flange shaft due to loosening and slipping of an inner ring is solved, and travelling safety is guaranteed. Besides, with the adoption of the measurement method, argumentation for reasonability of structural design of a spin riveting structure can be performed, and reasonable technological paramet
