Working principle of hydraulic locknuts
Hydraulic locknuts ensure the stability of the threaded connection by providing a uniform and powerful thrust through the hydraulic system. The principle of operation is that the pressure ring is hydraulically actuated so that it presses against the bushing and the plunger is pressed in by the adjusting screw, thus clamping the workpiece. The amount of clamping force is directly indicated by a pressure measuring rod.

Applications of hydraulic locknuts
Hydraulic locknuts have a wide range of applications in many fields and scenarios, including the following:
Metallurgy and metal processing industry:
Hydraulic locknuts are widely used in the metallurgical copper and aluminium metal industry and the paper industry. For example, hydraulic locknuts are used on slitting machines to lock the circular blades and sleeves to ensure the accuracy of the slit strip. The traditional hammering method is not only labour-intensive, but also the locking force is not uniform, while the hydraulic lock nut provides uniform and strong thrust through hydraulic propulsion, which is easy to operate and has significant effect.
Mechanical equipment:
Hydraulic locknuts are used in mechanical equipment to fasten shaving discs. Conventional hexagonal nuts tend to deform machine arbors and affect accuracy. Hydraulic locknuts are hydraulically driven to clamp the shaving discs uniformly, ensuring the accuracy and stability of the machine.
Bearing mounting and dismounting:
Hydraulic locknuts are also used for the mounting and dismounting of spherical roller bearings with tapered bore. The bearing clearance is adjusted by means of hydraulic advancement, which is suitable for large tapered hole spherical roller bearings with attached tightening and unloading sleeves.
Other application scenarios:
Hydraulic locknuts are suitable for a variety of vibration, fast rotation, high force equipment and narrow space. Its features include light weight, high precision, and can be used with hand pumps, pneumatic hydraulic pumps and electric hydraulic pumps. The standard working pressure is 150MPa, special requirements can reach 250MPa .
