The JRDA rotary seal can be used as a sealing element for rotating machine parts. It is mainly used in rotary feed units for separation of oil or other fluids at different pressures and can be subjected to pressure on both sides. Since the seal requires only a small installation space, the external dimensions of rotary feed units can be kept to a minimum.For application of JRDA outside sealing in rotary feed units with minimal installation space and low friction,such as construction machinery,automotive equipment,etc.
Petroleum-based hydraulic oil, flame retardant hydraulic fluid, bio-oil, water, air, etc.
