The stabilizer piston, part 550 425 38, is the moving member of a hydraulic stabilizer cylinder, the part that pushes out and holds a Sandvik rig steady against the reaction of drilling. Its job is to stay where it is put under load, which means the seals around it must hold pressure with no creep, and the piston surface they ride on has to be smooth and free from scoring to keep doing that.

A stabilizer that slowly sinks while the rig is working, or has to be re-extended during a hole, points to leakage past the piston or its seals, and a scored piston surface is a frequent cause that new seals alone will not cure. Checking the surface for scratches and corrosion pits before the seals are changed saves repeating the job. Because the piston is matched to its cylinder bore, replacing it by part number keeps the diameter and stroke that the stabilizer was designed around. Stalroc quotes this Sandvik reference by part number and exports worldwide to mining, quarrying, and drilling contractors.
