Customer OEM Manufacturer Hydraulic Screw Nut

Hydraulic Nut Series

Customer OEM Manufacturer Hydraulic Screw Nut

The hydraulic nut has proved to save considerable effort when mounting or dismounting rolling bearings with tapered bores. It comprises two main components: a steel ring with a groove in one side face and internal thread (a) and an annular piston which rests in the groove (b). The seal (c) between the two parts consists of two O-rings. When oil is pumped into the pressure chamber (d), the piston is pressed out with a force which normally is sufficient for mounting and dismounting rolling bearings. The outer ring is provided with an unthreaded hole (g) to hold a dial indicator (h). The measuring tip of the indicator will rest against the shoulder of the piston indicating the axial travel of the same. (NB! The drive-up distance can be used to determine correct mounting; please further see MP512). For the attachment of the oil leads, there are two threaded holes, one in the side face of the steel ring (e) and the other in its cylindrical outside surface (f). The hole which is not in use is plugged with a ball plug, this being supplied with the nut. All hydraulic nuts are equipped with nipple 729832 A for quick connection to the oil supply. A spare set of O-rings, a maintenance set and a round section bar for tightening the nut are all included as standard.

Model: YAX-HMVC

    Features

    Hydraulic nut for mounting or dismounting of bearings, with inch thread.  
    Facilitates easy and quick application of the high drive-up forces required for mounting bearings on tapered seatings.
    The hydraulic nut can also be used for dismounting bearings mounted on either adapter or withdrawal sleeves.    
    Quick connection coupling can be fitted on the face or side of the nut A spare set of piston seals and maintenance kit is included.    
    Supplied with a quick connection coupling to fit the hydraulic pumps. 
    Equipped with eyebolts, two tommy bars and four mating holes on their front face.

    Maintenance

    • When the nut is not in use, it should be protected against rust and any oil supply leads should be plugged to prevent entry of dirt.

    How to apply the nut

    • To enable easy mounting especially for larger nuts, it is important that the nut is properly centred on the mating thread before screwed on. For bigger nuts a proper support has to be created under the nut. One way of doing this is to use a special mounting tool similar to that shown on the picture. When the bearing is mounted on a sleeve, make sure that the sleeve is straight, i.e. the thread is aligned over the slotted part of the sleeve. It is recommended to always use a thread lubricant before applying the nut on the mating thread. When the nut is to be applied, a suitable length of round section bar is provided with the nut to be used as a handle. This is inserted in one of the four unthreaded holes in the outside cylindrical surface, or in one of the two holes on the side surface.
