DESCRIPTION
“Radial Seal MR19 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 a rubber part with fabric reinforcement on the sliding surface, which thanks to two edges forms an oil groove and two plastic anti-extrusion rings.
High and secure static sealing, also high and low temperature resistance in case of suitable compound selection, low friction
and stick-slip free operations
