Radial Seal MR17 is double-acting rod seal and are used in hydraulic rotary transmission systems.
It seals the pressure lines from each other and are suitable for high hydraulic pressures in the case of pivoting motions.
It consists of rubber part that firmly carry fabric blocs on both side providing lubrications on sliding surfaces. These fabric bloks contacting surfaces of housing prevent the seal from extruding into the sealing gap and circumference deformation. Has high and secure static sealing.
