A high pressure water/abrasive jet cutting nozzle has a pair of centering rings that act through body-mounted balls to position a nozzle element-holding collet. The interior surfaces of the centering rings are eccentric with respect to the longitudinal axis of the nozzle assembly so that rotation of a centering ring will cause the nozzle element collet to shift transversely. By rotating one or the other, or both, centering rings the axis of the nozzle element can be adjusted relative to the nozzle jet-forming element so as to align the nozzle element with the water jet.
