Hydraulic Nut Series

-YAXNOVA is producing the hydraulic nut for many years, also we have large production capacity and many experience, the reference of foreign products of relevant technology combined with manufacturer of developing researching production requirements into series products.
-The product is suitable for the bolt and nut must often; super bolt be preloaded.
-Large workpieces lock. 
-Also we can do hydraulic over surplus connection disassembling tools.    

Model: YAX-YM

Hydraulic nuts HYDNUT are used to press parts with a tapered bore onto a tapered seat. They are mainly used if the drive-up forces required cannot be applied using other accessories, e.g. shaft nuts or pressure screws.

Hydraulic nuts are used mainly for the assembly of rolling bearings with a tapered bore. The rolling bearings can be seated directly on a tapered shaft, on an adapter sleeve or on a withdrawal sleeve. If the bearing is fitted using a withdrawal sleeve or an adapter sleeve, the hydraulic nut can also be used for removal.

A hydraulic nut is also suitable for the assembly and loosening of press-fit parts such as ship propellers, rudder blades, shaft couplings and toothed gears.

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

-YAX-HMV Series hydraulic nut is mainly used for seamless connection of fitting, its working principle is to use oil in shaft ultra produce a thrust and bushings produce a tension, the shaft and bushings stress evenly together.

-Have axial and radial note oil in two ways.

-The pressure evenly among pressure ring.

-Standard working pressure 0-150Mpa.
