A kind of combined high-pressure slip ring sealing,combined tapered-slip-ring sealing was developed.Two O-shaped rubber rings were used to elevate the extrusion of slip rings,and a metal ring was used between them so that the left one can press the right one through the metal ring by internal pressure of seal cage to increase the pressure on the right of the slip ring.A set of elastic components were installed on the left of the slip rings.

These elastic components were pressed before installation,which can provide a sealing drive by their restoring force when there is no inner pressure so as to ensure the sealing being at good condition when it is started up,The combimed sealing has wear-self compensation function and the function of automatically adjusting the compression ratio of the section diameter of O-shaped seal ring in accordance with the pressure in seal cage.Therefore,it can be applied in bad seal environment even serious wear.

The numerical simulation indicates that kind of combined sealing has a sufficient sealing performance under high pressure,and the safety factor of the sealing is reasonable.

Slip ring combined sealing is a slip ring sealing structure that installing between O-Shaped ring and sliding surface.Nowadays, exsited functions of slip ring combined sealing are realizing  through eslatic resilience makes slip ring stick on sliding surface tightly after O-shaped ring storing strain capacity, O-shaped ring is static seal,slip ring is dynamic seal.

This seal struture avoids the disadvantages of friction of elastic assembly launch and slow motion clawl,eliminate the bad influence of O-shaped ring snap-off,twist-off and friction heat,which its low resistence,long service span,apply to seal surface and line,high speed etc.

LPT038 Series Slip Ring

with Through Bore 38.1mm


This unit can be used in any electromechanical system that requires unrestrained, intermittent, or continuous rotation while transferring power or data.

The LPT038 provides an economical, readily available solution when a compact through-bore configuration is required. This unit provides a 38.1mm through-bore for routing hydraulic or pneumatic lines and a compact 86mm outside diameter for minimal space applications. The 15 amps per circuit are available in 6, 12, 18 and 24 ring configurations in 4 housing lengths. Similar in design to our very popular LPT038 series, this design features long life, fiber brush contact technology for ultimate performance in many challenging applications. Fiber brushes do not require lubrication and produce virtually no wear debris, for maintenance free, life time operation.
