SL-HYDNUT Hydraulic Nut For Dismantling Bearings

Sometimes mounting bearings in tapered housings can be a difficult and time-consuming process. However, with SOLY hydraulic nuts, mounting is very simple. Their use, especially for larger bearings, saves the need for heavy and time-consuming assembly work using shaft or socket nuts, impact spanners etc.
Removing bearings with tapered bores from the retaining or withdrawal sleeves is often a difficult and time-consuming task. However, with the help of the SOLY hydraulic nut, this task can often be carried out easily. To do this, the hydraulic nut is screwed onto the sleeve and supported on the block or bearing. After connecting the oil pump, oil is pumped into the hydraulic nut, which moves the ring piston until the bearing comes loose.

SL-HN Hydraulic Nuts for Upper Loads

Hydraulic nuts for upper loads can be set to a precise preload with an accuracy of up to 3% earth; they can be supplied with a stroke indicator that allows the amount of tension to be observed, measured and controlled during operation.

SL-HN series top load hydraulic nuts are especially suitable for tightening in narrow spaces and heavy duty vibrating machinery, and can be assembled with several bolts at the same time. The torque-free design avoids friction, bolt twisting and other factors affecting bolt preload, and the tightened bolt is subjected to pure tensile force.

SL-HMVC Fractional Thread Hydraulic Nuts

Bearing assembly and disassembly uses hydraulic nuts – inch threads.Its working principle is through a high-pressure oil pump will be injected into the nut of hydraulic oil, push the piston to produce axial tensile force, the use of the material’s own elasticity will be thread locking, so as to achieve the effect of pre-tightening and anti-loosening.

Merry Christmas and Happy New Year from the SOLY team!
