The SKF hydraulic nut of the HMVA series is a mounting tool that threads onto the shaft and allows oil to be injected under pressure to expand the bearing inner ring. It is used in installation and removal tasks where mechanical methods are not enough, especially on large bearings or with interference fits. MR Accesorios Industriales sells this line for workshops, plants and heavy maintenance in Argentina.

The HMVA series designation is read as a hydraulic tool code: the letters identify the family and the number that follows indicates the shaft diameter range for which it was designed. For example, in model HMVA 42/200, 42 is the nut size code and 200 is the measurement that appears after the slash. It is not a bearing or a component that remains mounted on the machine: it is a mounting accessory that is removed once the operation is finished. That is why it does not carry sealing, clearance or cage suffixes like other products.

In Argentine industry, this nut is used in the assembly and disassembly of bearings in mining, cement, steel, mill, press and paper machine equipment. Also in maintenance workshops that receive large bearings and need to mount them without blows or heaters. By injecting oil under pressure between the fitting surfaces, effort is reduced and damage to the ring or shaft is avoided. It is commonly seen in scheduled bearing replacement tasks in gearboxes and large-diameter rolls.

To choose the correct hydraulic nut, take into account the shaft diameter and thread type, the expansion range you need and the working pressure of your hydraulic pump. Cleaning the threads and contact surfaces is key: any burr or dirt can damage the nut or the bearing. Before using it, verify that the oil is suitable and that the system has no leaks. Always follow the manufacturer's instructions for maximum pressure and the mounting procedure.

Hydraulic nuts from different brands can be interchanged if the shaft diameter, thread pitch and working range match. It is not enough for the code to be similar: the technical specifications must be compared. In the case of SKF, the HMVA series is a reference within its hydraulic tool line, and MR Accesorios Industriales sells it.
