For bearing mounting jobs that call for oil injection rather than force, the SKF HMVA hydraulic nut threads onto the shaft and pushes oil between the fitting surfaces to expand the inner ring. It is a tool, not a component that stays on the machine, so it comes off as soon as the bearing is seated. MR Industrial Accessories supplies this line to workshops and plants across the United States and Latin America.

Reading the HMVA code is straightforward once you know the pattern: HMVA identifies the hydraulic nut family, and the figures that follow describe the size. In HMVA 42/200, for instance, 42 is the nut size code and 200 is the value after the slash. Because it is a mounting accessory rather than a bearing, you will not find clearance, cage or seal suffixes attached to it.

These nuts show up wherever large bearings are fitted with an interference fit and mechanical methods fall short: mining, cement, steel, paper and rolling mill equipment, gearboxes and large-diameter rolls. Maintenance shops that receive oversized bearings also rely on them to seat rings without hammer blows or heating. Injecting oil under pressure between the mating surfaces lowers the effort required and keeps the ring and shaft from being damaged.

Sizing the right nut starts with the shaft diameter and thread type, followed by the expansion range you need and the working pressure your hydraulic pump delivers. Clean threads and contact surfaces matter, since a burr or grit can harm the nut or the bearing. Check that the oil is appropriate and that the system holds pressure without leaks, and follow the manufacturer's limits and procedure for maximum pressure and mounting.

Nuts from different makers can be swapped when shaft diameter, thread pitch and working range line up, but a similar code alone is not enough; compare the technical data. The SKF HMVA series is one reference among hydraulic tools, and MR Industrial Accessories supplies it. Share your application details and we will help you identify a matching equivalent.
